Sakai 3What and why and when and

how?March 2009

Michael Korcuska

Why Sakai 3?

Technology and Developer Experience

Functionality & User Experience

Community Practices and Culture

Why Sakai 3 Now?

The time to repair the roof is when the sun is shining.

John F. Kennedy

USER PERSPECTIVEWhy Sakai 3?

6

Sakai 3 for Users

• Changing expectations• Google docs/apps, Social

Networking, Web 2.0• Success of project sites =

Sakai beyond courses

• New technologies• Standards-based, open

source projects• JCR (Jackrabbit)• Open Social (Shindig)

• Client-side programming• JavaScript/AJAX

7

Content Tagging & Management

Sakai 3 Themes

Content Authoring

Academic Networking Breaking the Site Boundary

Academic Workflows, not (just) Tools The unSakai

8

Content Authoring

• Content Basics:• Simple page creation (wiki-

like)• WYSIWG Editing• Template-based authoring• Versioning

• Interactive Widgets

9

Tagging & Management

• Everything is content• Classic “resources”• Discussion post, user profile, test questions• Taggable, searchable, linkable, portable

• Unified content repository• Content not tied to site• Everything in one storage area

• BUT: Sakai is not a full Content Management System

10

Sakai 2

Site A Site B

Users find things by remembering what site they added it to

?

11

Tags: System, Organizational & User

Search

Sakai 3

Smart Folders

12

Benefits

• Web 2.0 “search” interaction supported• Tagging & content search

• Smart Folders retain hierarchical structure if desired• Folders for each site, each user and more

• Portfolio and other “cross-site” needs• Tags allow simple aggregation of diverse content• Organizational & User tag systems support

multiple portfolio requirements

13

Academic Networking

• Academic Networking• People are important, but “friends” aren’t enough• Content-based – Who is reading the same articles?• Activity based – Who has taken the same classes?

Content People

14

Sakai 2: Users & Sites

Site A Site B

Group A1

User 1User 2User 3User 4User 5...User N

Group B1

User 1User 2User 3User 4User 5...User N

Users and groups exist within the context of a site.

Sakai 3 Groups & Sites

• Groups & Sites managed separately• Member of a group – People with something in

common• Access to a site– Collection of content & functionality• Support for hierarchy

Kernel

• Workflows built across services• Encourages presentation &

service separation

• Services need to respond to more customers• UX oversight is more

complicated

18

Academic Workflow

• Beyond Tool Silos• Academic work flows often cross tool boundaries

• Anything can be graded!• Anything can be discussed!

• This is beginning to appear in Sakai 2• Examples: Open Syllabus, Assignments 2• But it is too difficult and more needs to be done

• Example: Instructor puts into syllabus an assignment to create a discussion post that will be graded.• 4 tools for both instructors and students!

The unSakai

• Multiple Configurations• Sakai as CMS• Sakai as Collaboration System• Sakai as Portfolio System

• Sakai Integrations• Google Applications• Social Networks (Open Social, Facebook)

Documented data feeds allow Sakai to appear anywhere

unSakai Economics

• We want to position Sakai for a transition to the “we don’t need no stinking LMS”

• We don’t care about “owning” the enterprise• We aren’t afraid of eroding license fees

because other applications take over “core LMS” features

SAKAI 3 DEMO

http://3akai.sakaifoundation.org

SAKAI 3 TECHNOLOGYWhy Sakai 3?

27

Sakai 3 Technology Goals

• Scalability• Remove bottlenecks from Sakai 2• Improve cluster support

• Developer Productivity• Faster builds• UX & back-end development separated

• Code Quality & Maintenance• Reliance on other open source efforts• Increase unit testing

• Easier to install/build• To improve initial experience for new developers

28

JCR as Content Store

• Standards-based• JSR 170• Ships with Apache Jackrabbit, but can be changed

• Everything as content• Discussion post, User profile information, etc.• Components put Content into JCR Content store• Sakai Kernel creates relational indices in DB• Component doesn’t need to do anything• Automatic tracking of most events by kernel

The Point

• Don’t write our own code• Criteria:• Functionality• License-compatible open source• Open standard• Approachable community

30

JSON

• Sakai Kernel supports JSON microformat• Components use REST calls to interact with Kernel• Again, standards based• JAX-RS currently in Kernel (JSR 311)

• Benefits• Back-end services stay Java-based• UX programmers more often skilled in JavaScript

• Easier UX developers can work on Sakai• Tools like GWT can be used for Java-based UI• Components can be written using other languages

Sakai 2.5

Sakai 2.8?

New Adoptions: 2 or 3?

• It Depends!• Of Course

• On what?• Your production timeline• Your appetite for running “.0” software• Your functional needs

Adopting 2 or 3?

2.6 or 2.7• Sakai 2 works well today• 3 doesn’t exist yet

• The best path to 3 will be through 2• Bb/WebCT migration to 3

is undefined• Bb/WebCT migration to 2

is well known• Many will be migrating

from Sakai 2 to 3

Straight to 3• You don’t have a

CMS or you are using something like SharePoint

• Your production timeline is 2012 or later

Adopting 2 or 3?

• Maybe the wrong question• Adopt both!• Hybrid mode• Sakai 2 for courses, Sakai 3 for project

collaboration• Gradually move users to Sakai 3

COMMUNITY PRACTICES

Community Practices

• Functional Leadership• Design First• Minimize Technology Frameworks• Quality Focused• Unit (and other) Tests
