ABSTRACT

We are living in a digital world which is governed by computers

New technologies are emerging every day because of several research and

development projects But management of the project development is a

challenging and complex task To make this management easier we propose

our project lsquoProject Collaboration Toolrsquo

Collaboration makes the management more complicated when

there are more than one person involved in the project development It is

difficult for all the members of a team to work in a single geographical location

Even if the developers (collaborators) are working on a project at the same

place merging the individual components is difficult

When two or more developers collaborate on a project there may

be the necessity to replicate data Although replication increases reliability

duplication of work is required to update every replicated copy To overcome

these difficulties we propose the ldquoProject Collaboration Toolrdquo which aims at

helping the developers to collaborate easily and to make the project

development efficient

Although there are several collaboration tools available they do

not provide the notification facility where each member of a project is intimated

when a new class method or interface is created during the development

process The notification can be one among desktop notification email

notification or SMS notification This facility will help to avoid the duplication

of work so that lot of time will be conserved

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

47 FUTURE ENHANCEMENTS

The following enhancements are proposed to be included in the

lsquoCollaborationrsquo application in the future

471Meeting module

When a meeting is to be scheduled the notification should be posted to all

the members who should attend the meeting and a slot has to be allotted in their

calendars

472Social Networking Integration

The application could be integrated with available social networking

sites like Facebook Twitter etc so that every notification is posted directly in

the social networking account

473Exporting of reports

Reports must be able to be stored in some form like pdf so that they are

available for producing to the clients

474Knowledge transfer request

A concept can be learnt by a member from some other member by fixing

an appointment so that effective knowledge transfer takes place

475Instant Messaging (Chat)

Chatting module has to be implemented so that the members can discuss

about their project online

476Migration support

Migration of user support has to be provided for the lsquoCollaborationrsquo

application

477Task progress

Task progress can be monitored by the team leaders The progress of each

task will be updated by the performer of that task at regular intervals (for

example at the End of the day)

ABSTRACT

We are living in a digital world which is governed by computers

New technologies are emerging every day because of several research and

development projects But management of the project development is a

challenging and complex task To make this management easier we propose

our project lsquoProject Collaboration Toolrsquo

Collaboration makes the management more complicated when

there are more than one person involved in the project development It is

difficult for all the members of a team to work in a single geographical location

Even if the developers (collaborators) are working on a project at the same

place merging the individual components is difficult

When two or more developers collaborate on a project there may

be the necessity to replicate data Although replication increases reliability

duplication of work is required to update every replicated copy To overcome

these difficulties we propose the ldquoProject Collaboration Toolrdquo which aims at

helping the developers to collaborate easily and to make the project

development efficient

Although there are several collaboration tools available they do

not provide the notification facility where each member of a project is intimated

when a new class method or interface is created during the development

process The notification can be one among desktop notification email

notification or SMS notification This facility will help to avoid the duplication

of work so that lot of time will be conserved

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

ABSTRACT

We are living in a digital world which is governed by computers

New technologies are emerging every day because of several research and

development projects But management of the project development is a

challenging and complex task To make this management easier we propose

our project lsquoProject Collaboration Toolrsquo

Collaboration makes the management more complicated when

there are more than one person involved in the project development It is

difficult for all the members of a team to work in a single geographical location

Even if the developers (collaborators) are working on a project at the same

place merging the individual components is difficult

When two or more developers collaborate on a project there may

be the necessity to replicate data Although replication increases reliability

duplication of work is required to update every replicated copy To overcome

these difficulties we propose the ldquoProject Collaboration Toolrdquo which aims at

helping the developers to collaborate easily and to make the project

development efficient

Although there are several collaboration tools available they do

not provide the notification facility where each member of a project is intimated

when a new class method or interface is created during the development

process The notification can be one among desktop notification email

notification or SMS notification This facility will help to avoid the duplication

of work so that lot of time will be conserved

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

When a meeting is to be scheduled the notification should be posted to all

the members who should attend the meeting and a slot has to be allotted in their

calendars

472Social Networking Integration

The application could be integrated with available social networking

sites like Facebook Twitter etc so that every notification is posted directly in

the social networking account

473Exporting of reports

Reports must be able to be stored in some form like pdf so that they are

available for producing to the clients

474Knowledge transfer request

A concept can be learnt by a member from some other member by fixing

an appointment so that effective knowledge transfer takes place

475Instant Messaging (Chat)

Chatting module has to be implemented so that the members can discuss

about their project online

ABSTRACT

We are living in a digital world which is governed by computers

New technologies are emerging every day because of several research and

development projects But management of the project development is a

challenging and complex task To make this management easier we propose

our project lsquoProject Collaboration Toolrsquo

Collaboration makes the management more complicated when

there are more than one person involved in the project development It is

difficult for all the members of a team to work in a single geographical location

Even if the developers (collaborators) are working on a project at the same

place merging the individual components is difficult

When two or more developers collaborate on a project there may

be the necessity to replicate data Although replication increases reliability

duplication of work is required to update every replicated copy To overcome

these difficulties we propose the ldquoProject Collaboration Toolrdquo which aims at

helping the developers to collaborate easily and to make the project

development efficient

Although there are several collaboration tools available they do

not provide the notification facility where each member of a project is intimated

when a new class method or interface is created during the development

process The notification can be one among desktop notification email

notification or SMS notification This facility will help to avoid the duplication

of work so that lot of time will be conserved

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

2

CHAPTER 2

LITERATURE SURVEY

The following are few of the existing systems for which we have

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

2

CHAPTER 2

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

2

CHAPTER 2

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

47 FUTURE ENHANCEMENTS

The following enhancements are proposed to be included in the

lsquoCollaborationrsquo application in the future

471Meeting module

When a meeting is to be scheduled the notification should be posted to all

the members who should attend the meeting and a slot has to be allotted in their

calendars

472Social Networking Integration

The application could be integrated with available social networking

sites like Facebook Twitter etc so that every notification is posted directly in

the social networking account

473Exporting of reports

Reports must be able to be stored in some form like pdf so that they are

available for producing to the clients

474Knowledge transfer request

A concept can be learnt by a member from some other member by fixing

an appointment so that effective knowledge transfer takes place

475Instant Messaging (Chat)

Chatting module has to be implemented so that the members can discuss

about their project online

476Migration support

Migration of user support has to be provided for the lsquoCollaborationrsquo

application

477Task progress

Task progress can be monitored by the team leaders The progress of each

task will be updated by the performer of that task at regular intervals (for

example at the End of the day)

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

2

CHAPTER 2

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

47 FUTURE ENHANCEMENTS

The following enhancements are proposed to be included in the

lsquoCollaborationrsquo application in the future

471Meeting module

When a meeting is to be scheduled the notification should be posted to all

the members who should attend the meeting and a slot has to be allotted in their

calendars

472Social Networking Integration

The application could be integrated with available social networking

sites like Facebook Twitter etc so that every notification is posted directly in

the social networking account

473Exporting of reports

Reports must be able to be stored in some form like pdf so that they are

available for producing to the clients

474Knowledge transfer request

A concept can be learnt by a member from some other member by fixing

an appointment so that effective knowledge transfer takes place

475Instant Messaging (Chat)

Chatting module has to be implemented so that the members can discuss

about their project online

476Migration support

Migration of user support has to be provided for the lsquoCollaborationrsquo

application

477Task progress

Task progress can be monitored by the team leaders The progress of each

task will be updated by the performer of that task at regular intervals (for

example at the End of the day)

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

CHAPTER 1

INTRODUCTION

We are living in a digital world which is governed by computers The

role of computers is indispensable since they play a vital role in the fields of

education business and media and so on New technologies are emerging

everyday because of several research and development projects New software

is being invented in order to meet the requirements of the modern world But

management of the project development is a challenging and complex task

Collaboration makes the management more complicated when there is

more than one person involved in the project development It is difficult for all

the members of a team to work in a single geographical location Even if the

developers are working on a project at the same place merging the individual

components is a difficult task

When two or more developers collaborate on a project there may be a

necessity to replicate code This improves the reliability of the code as it is

available in more than one location However there is a serious problem of

inconsistency if the replicated copies are not updated correctly

Hence we proposed and implemented a tool that allows easy online

collaboration of the project development process This tool has been

implemented (using the famous LAMP architecture) as a plug-in for an open

source private cloud software called Own Cloud

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

8

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation

47 FUTURE ENHANCEMENTS

The following enhancements are proposed to be included in the

lsquoCollaborationrsquo application in the future

471Meeting module

When a meeting is to be scheduled the notification should be posted to all

the members who should attend the meeting and a slot has to be allotted in their

calendars

472Social Networking Integration

The application could be integrated with available social networking

sites like Facebook Twitter etc so that every notification is posted directly in

the social networking account

473Exporting of reports

Reports must be able to be stored in some form like pdf so that they are

available for producing to the clients

474Knowledge transfer request

A concept can be learnt by a member from some other member by fixing

an appointment so that effective knowledge transfer takes place

475Instant Messaging (Chat)

Chatting module has to be implemented so that the members can discuss

about their project online

476Migration support

Migration of user support has to be provided for the lsquoCollaborationrsquo

application

477Task progress

Task progress can be monitored by the team leaders The progress of each

task will be updated by the performer of that task at regular intervals (for

example at the End of the day)

PROJECT DESCRIPTION

In order to avoid the disadvantages in the existing systems we propose

our project ldquoPROJECT COLLABORATION TOOLrdquo consists of various

features as listed below This project has a wide range of features like Progress

management Scheduling Task management live conversation notification amp

messaging knowledge management report generation burn down reports

version control system file content management and timeline view

41 PROJECT SCOPE

The scope of this project is to provide a user friendly environment for the

project developers who want to collaborate the development with their

(geographically distributed) team Our proposed project will help the project

collaboration process much simpler Our project will help several organizations

team developers and college students for easily develop and collaborate with

each other from different locations This project will help the individuals who

find the integration of individual modules difficult

This project will be useful for team members team leaders individual

developers organizations etc for easily collaborating and managing the project

The goal of this project is to support the project collaboration and it does not

aim at providing a platform for coding However this project can be used for

sharing and distributing the code to the members involved in developing the

project

42 TECHNICAL FEASIBILITY

Since our project is implemented as a web project using LAMP (Linux

Apache MySQL PHP) all the resources are available at free of cost and hence it

was technically feasible for us to implement this project

43 TIME FEASIBILITY

As our team had previous working experience in the Linux platform we

were able to analyse design develop and test our project within the given time

period

44 LAMP ARCHITECTURE

LAMP stands for Linux Apache MySQL and PHP Each of these terms

is explained as follows

441 Linux

It is an open source operating system (in fact Linux is a kernel)

developed by Linus Trovalds There are many flavours of Linux available today

like Ubuntu Fedora CentOS RedHat etc All these operating systems are

available free of cost OwnCloud server is designed to be configurable on Linux

platform Hence the Linux operating system had been chosen for the

development of this project

442 Apache

Apache is an open source server software which is used for serving the

clients which request the web pages This is one of the most famous servers

used commonly with Linux Since ownCloud supports Apache server it is used

as the server for the project

443 MySQL

Though other database management systems are supported by ownCloud

including PostgreSQL MySQL had been chosen as DBMS as it is convenient

and easy to integrate with PHP

9

444 PHP

Hypertext Preprocessor (PHP) is a HTML-embedded scripting language

commonly used for server side scripting Since ownCloud is developed using

PHP and all the ownCloud applications can created in PHP the development

language chosen for this project is PHP

45 FEATURES

451 Features of ownCloud

4511 Data access synchronization amp sharing

OwnCloud allows storing of files folders contacts photo galleries

calendars and more on the userrsquos server The data can be accessed from mobile

devices or desktops whenever they are needed

It helps to keep your files contacts pictures and calendars synchronized

among all the devices Moreover since is supports version control

collaboration is much easier

OwnCloud provides features for sharing the data with others and giving

them access to latest photo galleries calendars music or anything else Sharing

can be public or private

4512 Restoring deleted files

Just as any other cloud storage system ownCloud also provides support for

undeleting or restoring the deleted files

4513 Integration with Google Drive amp DropBox

OwnCloud also provides external storage support which means that the

storage space on the server could either be the own storage or cloud storage

obtained from Google Drive DropBox and a few other vendors

10

4514 Security

The actual key encrypted with username acts as key for file encryption

Encryption algorithms used are

o Version 5 ndash Crypt Blowfish

o Version 6 ndash AES 128 bit

SSL certificate can be configured to run ownCloud so that it can be

opened with https protocol

SQL Injection is avoided since every query being executed is a prepared

statement

Cross Site Scripting (XSS) attack is avoided through the Content Security

Policy (CSP) which is recommended by W3C

o Eg Inline JavaScript is blocked

The following steps were used to configure SSL certificate for ownCloud

1 Install the openssl software that is used to generate the private and the

public keys through terminal For installation run this command in

terminal while the system is connected to the Internet

$ sudo apt-get install openssl

2 Enable the ssl and rewrite module in apache2 Use the following

commands

$sudo su -

a2enmod ssl

a2enmod rewrite

3 Create a ssl directory inside etcapache2

mkdir -p etcapache2ssl

4 To create a self-signed certificate enter the following command in the

terminal and fill the information that is being asked

11

$ openssl req -new -x509 -days 365 -nodes -out

etcapache2sslowncloudpem -keyout etcapache2sslowncloudkey

5 Edit the lsquoowncloudconfrsquo file

6 Restart the apache server and now ownCloud will open in https protocol

Since the signature is self-signed a warning message will appear and it

can be simply ignored

4515 File View in Browser

ownCloud provides a fascinating feature of opening the following file

types in the browser itself so that almost everything can be done under the same

browser window

PDF

Images

VCF cards

Audio

Video

Text Document (odt only)

Spreadsheet (ods only)

Plain Text documents (txt)

452 Features of lsquoCollaborationrsquo application

4521 Project Timeline

The project timeline aims at displaying the progress of the project It can be

used by the project leaders for monitoring the project progress and helps them to

track and take necessary actions in order to complete the project before the

deadline The progress of the project will be displayed in form of a timeline

view The progress is calculated using the formula

Progress =

12

4522 Task Management

A set of tasks will be allocated to the employeesrsquo along with their priorities

Before assigning a task to a particular member the team leader has the option to

view the skillsets experience and expertise of that particular member The team

leader can also view the number of tasks assigned so far to that member in

order to assign tasks to a member who is free

A task can have one of the following states

Unassigned ndash Task has been created but not assigned to anyone yet

In Progress ndash Task has been assigned to a member and currently is in

progress

Held ndash Task is awaiting for some resources

Cancelled ndash The purpose of the task is no more and hence the task has

been cancelled

Completed ndash The task has been completed by the team member and is

awaiting for verification by the team lead

Verified ndash The completed task has been verified and accepted by the team

leader

13

Fig 1 Task status diagram

When a task is newly created by the administrator (Team leader) the task

initially goes to the Unassigned state Once it has been assigned to a team

member the task then goes to the In Progress (Assigned) state If the team

member is waiting for some resource to complete the task assigned to himher

heshe may hold the task so that it goes to the Held state Later when the

resource becomes available the team member can resume the task to bring it

back to the In Progress state

Once the task has been finished it is put into the Completed state The

team leader then verifies whether the completed task is according to hisher

specification and can either accept or reject inorder to put the task in Verified

or In Progress states respectively The task may be cancelled by the team

leader when it is in unassigned in progress or held states Once a task has been

cancelled or verified no more changes are allowed on that particular task

14

4523 Dashboard

The list of all activities taking place in the projects is posted on the

dashboard of the users The users can view amp comment on the posts so that a

thread is maintained for each post

The dashboard page is made dynamic so that more and more posts get

loaded when the users scroll down to the bottom of the page This dynamic

loading is done with the help of the lsquoonscrollrsquo event of JavaScript where it calls

a PHP function though AJAX to fetch more posts from the MySQL database

The list of activities posted on the dashboard include

1 Project Creation

2 Project Update

3 Task Creation

4 Task Update (Status change)

5 FileFolder sharing

6 User removal

7 Custom posts

4524 Report Generation

Reports play a vital role for monitoring and tracking the project Reports are

helpful for understanding whether the project is progressing as expected and for

taking necessary actions if the project progress is less Contribution report helps

in knowing the number of tasks performed by every member This number of

tasks performed by a member can be directly used as a parameter for paying the

members on the basis of lsquopay per taskrsquo or for rewarding the members who have

carried out more number of tasks Graphical report in form of bar graph will be

generated for the contributions of individual developers

15

Knowing the number of tasks in each state is important as it gives an

overall view about the tasks in a project Report is available to view the number

of tasks in each state in form of pie chart This also tells whether there are

pending tasks (tasks in lsquoIn Progressrsquo or lsquoHeldrsquo state) in the given project so that

the team leader can know how many more tasks needs to be completed to

complete the project For the generation of the graphical reports the ltdivgt tag

of HTML amp Canvas of HTML5 was used

4525 File Content Management

All the files are stored in the data directory of the server and hence unless

and otherwise the password is breached the data will not be revealed to the

users other than the owner amp the ownCloud administrator If the security has to

be still improved the user can enable the lsquoEncryptionrsquo application so that their

files and folders are stored in encrypted format in the ownCloud server

For synchronizing files with the desktop server it is recommended to use

the ownCloud Client for Windows Mac OS X and Linux The ownCloud

Desktop Client helps to connect to the private ownCloud Server Folders can be

created in the local directory and can be synchronized with the ownCloud

server thorugh ownCloud client applications

ownCloud keeps a copy of your deleted files in case you need them again

To make sure that the user doesnrsquot run out of memory the deleted files app

manages the size of the deleted files for the user The app takes care to never

use more that 50 of your currently available free space If the deleted files

exceed this limit ownCloud automatically deletes the oldest versions until it

meets the memory usage limit again

16

4526 Version Control System

Multiple versions of each file will be maintained so that any versions of any

file can be used anytime This feature is inbuilt in ownCloud ownCloud

supports simple version control for files Versioning is enabled by default and

creates backups of files which are accessible via the history tab This tab also

links to the history page where you can roll back a file to any previous version

The versioning app expires and hence removes the old versions

automatically to make sure that the usersrsquo do not run out of space Following

pattern is used for creating versions

bull For the first 10 seconds ownCloud keeps one version every 2 seconds

bull For the first hour ownCloud keeps one version every minute

bull For the first 24 hours ownCloud keeps one version every hour

bull For the first 30 days ownCloud keeps one version every day

bull After the first 30 days ownCloud keeps one version every week

The versions are adjusted along this pattern every time a new version gets

created Beside that the version app takes care to never use more that 50 of the

usersrsquo currently available free space If the stored versions exceed this limit

ownCloud delete the oldest versions until it meets the memory usage limit

again

4527 Online Collaborative Document Editing

With ownCloud documents can be creatededited collaboratively Online

Collaborative Document Editing means a single document can be viewed and

edited by more than a person at the same time which saves the time taken for

17

merging the contents of one file into correct location of the other file This

feature will be very helpful for preparing the documentation of the projects

4528 Tasks view

The list of available tasks can be seen in the tasks view Tasks can be

filtered according to their status according to the project to which they belong

to and also according to the person who assigned it The tasks view is available

to both the team leaders as well as the team members The team leaders will use

the tasks view to identify the tasks whose deadlines are approaching and can

remind the corresponding team member about the deadline The team members

will use the tasks view to see the list of tasks that they have to complete

4529 Notification

If a particular announcement is to be made for individual member set of

members or to a group of roles it can be made through notifications The

notification will be posted on the intended membersrsquo dashboard with a subject

45210 Skill set

The users have the option to update their skill set by adding their own skills

along with their experience and expertise in that particular skill This is the

feature which is not available in most of the collaboration software available

today

45211 Email notifications

Automatic email will be sent to the members when one of the following

events happens

1 A new project has been created

2 A rolemember has been added to a project

3 A task has been assigned to a member

4 A notification is posted in the dashboard

18

5 Every day with a morning overview of the list of tasks to be done on a

particular day

Every time the email is sent only if the user wishes to in order to avoid

flooding the email accounts of the users Since multithreading is not available

in PHP the OSrsquos lsquocronrsquo (schedule) job is taken to initiate a morning overview of

tasks every 24 hours

45212 SMS alerts

When the deadline of a task is approaching the task is still incomplete a

reminder SMS is sent to the registered mobile number of the team member so

that heshe can try to complete that task within the given deadline

The following method is used for sending SMS alerts

1 The SMS server which is written in Java for Android will be running on

an Android mobile

2 The ownCloud server amp SMS server will be connected to the same

network

3 The SMS server will listen to a port on its lsquolocalhostrsquo

4 The ownCloud server knows the IP address of the Android mobile and

the port in which the SMS server is listening to

5 Whenever an SMS is to be sent the ownCloud server writes the mobile

number amp data to be sent into that particular IP amp port

6 The data amp mobile number are fetched by the SMS server and the

content is texted to that particular mobile number

45213 Task scheduling in calendar

Every time a task is assigned to a member the task is noted in the calendar

application so that the user can be aware of the tasks that heshe is currently

working in through the calendar application itself which also provides the

timeline view of tasks

19

45214 Responding to external events

For responding to the events taking place outside the lsquoCollaborationrsquo

application (the event taking place in another application ndash external events)

ownCloud provides a method called Hook In the collaboration application two

external events have been handled

When the user is removed from ownCloud

The tasks that were in progress by that user are changed to

unassigned state and a notification about the user removal is posted on the

dashboard of members working in the projects that the removed member

was working in

Whenever a user is removed from ownCloud the following things

happen

1 The tasks assigned to himher are automatically changed to the

Unassigned state if it is in In Progress Held or Completed states

2 A notification is posted on the Dashboard of the members of the project

in which the removed member was working in

3 The member is removed from all roles in the projects in which heshe

was working in

4 The skills of the member are removed

5 All the notificationsposts created by the removed member are deleted

When a filefolder is shared from one member to another

member

A notification is posted on dashboard indicating the member who

shared the filefolder amp the location of the shared filefolder

20

45215 Local language support (Internationalization)

All the strings were translated into Tamil (local language) using Transifex

website amp multi-language support has been provided to the lsquoCollaborationrsquo app

just as the other ownCloud applications The steps followed for the translation

of strings are as follows

1 Every string visible to the user in the application is given after passing

to the translation function which is defined in ownCloud

2 A perl file built-in with ownCloud is run with the lsquoreadrsquo command line

option to generate the pot (Portable Object Template) file

3 The pot file corresponding to the lsquoCollaborationrsquo application is uploaded

into a repository of the lsquoTransifexrsquo website

4 The string translations are done at lsquoTransifexrsquo with the help of

translategooglecom and many other websites

5 The po (Portable Object) file has been downloaded from the lsquoTransifexrsquo

file and placed inside the lsquol10nrsquo directory of the lsquoCollaborationrsquo app

6 The perl file is run once again but with the lsquowritersquo command line option

to generate an associative array in PHP for translation
