Sakai 3What and why and when and
how?March 2009

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 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
TIMELINES AND ADOPTION

Previews

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
