Abstract

Archaeology is a scientific study of the past and archaeologists are dealing with fragile

material remains of the past human cultures. Vast numbers of archaeological projects that

have different objectives produce enormous assemblages of artefacts. Beyond the

dilemma of purely academic nature the most decisive challenge face by the field

archaeologists is handling and archiving the materials unearthed by them. Most of the

field projects frequently remain with unsatisfactorily managed archival materials

including artefact indexes, field drawings, field notebooks and film negatives. Digital

archival systems now available in the world provide archaeologists a wide opportunity to

follow a systematic procedure to get manage such information effectively. Contrary,

this is one of the less focused areas of the current practice of archaeology in Sri Lanka.

Application of digital archiving system provides a range of advantages. Some of

them are sharing, exchanging and archiving documents effectively, Saving money, time

and space, disaster recovery, productivity, communication and collaboration, Levels of

client satisfaction, accuracy and security, go green, long term preservation, easy and fast

access to resources, and information sharing. This paper intends to discuss a viable

procedure of creating a digitalized archival database for archaeological field projects with

special reference to the existing problems in the current recording and documentation

practices.

Towards an Effective Digital Archiving Systemfor Archaeological Field Projects

1.1 Objectives

This paper has developed on three objectives, i.e. 1).To propose a new digital database

system for field of archaeology 2). To identify the constraints and 3).to makes

alternatives to overcome the problems.

1.2 What digital archiving means?

Digital archiving is a controlled mechanism of handling and storing data using computer-

based programs. Computer software’s provide facilities to store vivid categories of

datasets including spatial data (maps etc.) real-time recordings (photographs, videos) and

written accounts. The growing hardware techniques offer a considerably large space to

store different types of data in different formats. The best approach for long-term

preservation of archaeological data in digital formats is for them to be systematically

collected, maintained, and made accessible to users operating in very different computing

environments (Brown 1998).

Digital archiving is about preserving information regardless of the object on

which that information is stored. The content, structure, and context of the information

must be preserved in order for digital records to be migrated from one medium and

format to the next. This is because diskettes and other magnetic media degrade and

software and hardware change rapidly: the physical media on which digital data are

stored are impermanent (ibid 1998).

1.3 Digital archiving system in Sri Lanka

Sri Lanka is still lag behind in the process of acquiring IT base technology to handle

archival materials. Especially this could be explicit in the field of archaeology. Perhaps

this is due to the budgetary constraints of increasing consideration large amount of funds

to get use of IT base technology. But the advantages provides by such may justify

responsibility of even a heavy investment upon the digital archaeological system.

1.4 Introduction - WINISIS Database Software

A database is a collection of information that is organized so that it can easily be

accessed, managed, and updated. In one view, databases can be classified according to


types of content: full-text, bibliographic, numeric, and images. In addition Databases can

organize according to their organizational approach. CDS/ISIS for Windows or WINISIS

is the introductory database software for the field of archaeology.

WINISIS database software, developed by UNESCO, is flexible, easy to use,

menu-driven and generalized information storage and retrieval software. The software is

designed specifically for creating and managing textual databases and has capability to

create any number of databases with completely different data elements. (Rajasekharan

and Nafala 2000?).

WINISIS can be used for developing searchable digital archives of full text

documents in doc, xls, ppt, html, pdf, audio, and video or picture format. A database

created with WINISIS can be modified into digital archive by adding a command line in

its print format so as to display a hyperlink in the database display screen. The hyperlink

can link up the record to the appropriate document in the digital document collection. A

mouse click on the link will result in automatic opening-up of that document. WINISIS

application can be used by anyone having a reasonable computer experience (Ibid

2000?).

1.5 Technical Process of WINISIS

To create a WINISIS database with any chosen fields, need to define the following

components.

1. Field Definition Table (FDT): this is defines the fields such as Title of project,

Supervisor of project etc. of the records in the database and their characteristics.

FDT determines the nature of data entry worksheet.


1.1 Screen Shot: Field Definition Table

2. Data Entry Worksheet(s): The worksheet is the screen layout used to create and/or

update the records of the database. This is one of the key parts of this database.

Anyone can create this data entry fields according to their requirements.

1.2 Screen Shot: Data Entry Worksheet


3. Print Format (PFT): The PFT is the format for display or printing of records.

1.3 Screen Shot: Print Format

4. Field Selection Table(s) (FST): FST defines fields that can be searched in the

database. Search is made possible by creating an inverted file of terms indexed

from the fields chosen for search.

1.4 Screen Shot: Field Selection Table


WINISIS database facilitates digital archiving systems according to archaeological

requirements. I have made an attempt to list some of the important attributes that could be

considered as data fields as follows;.

1. Title of Project 2. Short Description of Project

3. Type of Project 4. Location of Project

5. Creators 6. Dates

7. Evidence in Archive 8. Bibliographic References.

Title of project is most imperative to identifying and searching project details. These

titles are given the clue of projects. As an example: Ranchamadama excavation, Alawala

excavation etc.

In one hand, short description of project will help to catch the most relevant

information which is pertinent to the excavation .On the other hand archaeologist should

have been mentioned their types of project and this project type may be a Surface survey,

Excavation, Watching Brief, Survey or any other type of monument etc. Fourth important

element is Location of Project. This is consisting of Site address, Site name, and Site

reference number, Parish, County and Nation. Creators is the fifth element of work sheet

and Name of organization, Address, Director/supervisor, Project manager and Sponsor or

funding body should be mention here. This Information is most helpful for archaeologists

in terms of endorsing the responsibility. Sixth element is Dates. Especially Fieldwork

started date, Fieldwork finished date and archive completed date should mention within

the form. Evidence in Archive is the seventh element of the project form. Finally

bibliographic reference also can mentioned.

1.6 Searching the Archive

There are two types of searching systems i.e. 1. Expert search 2. Guided search .Let us

see how to retrieve full text documents from the archive.


1. Step: Open the Expert Search box from Search menu

1.5 Screen Shot: Expert Search box

2. Step: Open Search Window and searching

1.6 Screen Shot: Expert Searching Box


3. Step: Search result for the term

1.7 Screen Shot: Expert Searching results

Click on the Green Colour Hyperlink to open full text Document (i.e. Databases, CAD,

Geophysics, GIS, Images, Movies, Spreadsheets, Statistics, Texts, Virtual Reality).


Hyperlink to Source

4. Step: Full text Document opened (You can read the map here)

1.8 Screen Shot: Map opened (Somadeva (2007), Ranchamadama Excavation)

Finally this documents can converted in to web based application with GenisisWeb

software .As a result users can access to archive via the World Wide Web (WWW).

1.7 Advantages of Digital archiving

Easy to back-up files ; Sharing, exchanging and archiving documents effectively, Save

money, time and space, disaster recovery, productivity, communication and

collaboration, Levels of client satisfaction, accuracy and security, go green, long term

preservation, easy and fast access to resources, Information Sharing ,user-friendly

mechanism are the benefits of WINISIS database software.

1.8 Difficulties encountered in the usage of Digital archiving

Several crucial problems pertaining to establish of the Digital Archiving System are :

stored in always fire-proof, anti-magnetic facilities separate from the original data files;

versioning control ; need to upgrade of hardware or software; lack of skills manpower,


lack of resources, lack of financial support, of Lack of database systems, lack of

infrastructural facility and fear for new technology and Virus attack

1.9 Suggestions

To participate local, international workshops, training staff, conduct in house workshops

and educated top management of the organization are the suggestion to develop this kind

of archiving system in Sri Lanka

1.10 Conclusion

There no any systematic method to preserve most important archaeological data and

information for future generation in Sri Lanka. Therefore this WINISIS database software

system may be extremely useful for field archaeology .I recommend that archaeological

information held in digital archives be made available to the widest number of people

possible.
