About Sakai
4
Sakai History Courseware Management System Started in 2004 Michigan, Indiana, Stanford, MIT (and Berkeley) Mellon Foundation Grant 2.6 release in QA
5
Why Start Sakai? 5 Schools with Homegrown CMS Inefficient to build 5 systems Wanted to maintain control Experts in teaching and learning Desire to work together and share knowledge
6
Why Sakai? Stanford wrote about 20% of the original code in Sakai. What we have received in return is five times what we have put in, a tremendous return on investment. The value of community source is very real to us. Lois Brooks Director of Academic Computing Stanford University Lois Brooks Director of Academic Computing Stanford University Coursework, Stanford University

Defining Sakai: Product Scope COURSE MANAGEMENT — all the tools of a modern course management system. RESEARCH & COLLABORATION — project sites for research and work group collaboration. SAKAIBRARY — Library-led component to add citations directly into Sakai. PORTFOLIOS — Open Source Portfolio (OSP) is a core part of Sakai. Course Management Portfolios Sakaibrary Research & Collaboration
8
Defining Sakai: Community COMPOSITION — educational institutions & commercial enterprises working in partnership with standards bodies & other open- source initiatives. GOALS — work collaboratively to develop innovative software applications designed to enhance teaching, learning, research & collaboration in education. VALUES — knowledge sharing, information transparency, meritocracy. Educational Institutions Commercial Affiliates Open Source Standards Bodies Standards Bodies

Increasing Global Diversity In 2006, 81% were in North America
14
Defining Sakai: Foundation MISSION — manage & protect intellectual property; provide basic infrastructure & small staff; help coordinate design, development, testing & distribution of software; champion open source & open standards. GOVERNANCE — ten board members elected by member reps to serve three-year terms; Executive Director manages day-to-day operations. PARTNERS — over 100 member organizations contribute $10K per year ($5K for smaller institutions). BUDGET — funds 4-6 staffers, admin services, computing infrastructure, project coordination, conferences, Sakai Fellows Program, advocacy & outreach activities.
15
Why Sakai? UCT decided to move to open source in 2004, migrating from WebCT & a home-grown system. Open source offers the advantages of flexibility & avoids the risks of vendor lock-in & escalating license costs. We were attracted to Sakai by the size & expertise of the community around it. Stephen Marquard, Learning Technologies Coordinator, University of Cape Town
16
Why Sakai 3? 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
17
Sakai 3 Themes Content Authoring and Management Academic Networking Breaking the Site Boundary Academic Workflows, not (just) Tools Sakai, Thick or ThinSakai Everywhere
18
Content Content Basics: Simple page creation (wiki- like) WYSIWG Editing Template-based authoring Versioning Interactive Widgets Everything is content Searchable, linkable, portable Unified content repository
19
Sakai 2 Site A Site B Finding something requires knowing which site it belongs to. ? ?
20
Tags: System, Organizational & User Search + Smart Folders Sakai 3
21
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?
22
Sakai 2: Users & Sites Site A Site B Group A1 User 1 User 2 User 3 User 4 User 5. User N Group B1 User 1 User 2 User 3 User 4 User 5. User N Users and groups exist within the context of a site.
23
Groups & Sites (call them spaces?) Separated Member of a group – People with something in common Access to a space – Collection of content & functionality Support for hierarchy Sakai 3 Groups & Sites Space A Space B Space C Group 2 Group 3 Group 1 Group 1.1 Space AA Space AB Group 1.2
24
Kernel Tool Sakai 2 Architecture Kernel Service Facilitates independent tool development Resists intuitive workflows Contributes to inconsistent user experience Kernel
25
Sakai 3 Architecture Kernel Workflow Kernel Service Kernel Workflows built across services Encourages presentation & service separation Services need to respond to more customers UX oversight is more complicated
26
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 But 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!

Sakai, Thick or Thin Multiple Configurations Sakai as CMS Sakai as Collaboration System Sakai as Portfolio System Sakai Integrations Google Applications Social Networks (Open Social, Facebook)
31
Sakai Everywhere
32
http://3akai.sakaifoundation.org Sakai 3 Demo
34
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
35
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
36
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
37
Sakai 3 Participation K2 Working Group http://groups.google.com/group/sakai-kernel UX Design Work UX list http://groups.google.com/group/3akai How would you like to be involved? Development Java & JavaScript Design Conceptual, interaction and visual
38
When Q1 2009: Sakai 2.6 Q3 2009: Sakai 2.6.# A maintenance release for fall production 2010 Q1: Sakai 2.7 (New assignments tool and gradebook?) Later: First versions of Sakai 3 Not functionally equivalent to 2.7 Suitable for new adoptions “Hybrid” version for existing Sakai schools 2011 Sakai 3 as full replacement Maintenance releases for Sakai 2.7 through 2013 No version 2.8
