Transcript

  • 1. Sakai UpdateMichael Korcuska<br />March 17, 2009. Nagoya, Japan<br />
  • 2. About Sakai<br />
  • 3. Sakai History<br />Courseware Management System<br />Started in 2004 <br />Michigan, Indiana, Stanford, MIT (and Berkeley)<br />Mellon Foundation Grant<br />2.6 release in QA<br />
  • 4. Why Start Sakai?<br />5 Schools with Homegrown CMS<br />Inefficient to build 5 systems<br />Wanted to maintain control<br />Experts in teaching and learning<br />Desire to work together and share knowledge<br />
  • 5. Why Sakai?<br />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.<br />Lois Brooks<br />Director of Academic Computing <br />Stanford University<br />Coursework, Stanford University<br />
  • 6. Course Management<br />Research & Collaboration<br />Sakaibrary<br />Portfolios<br />Defining Sakai: Product Scope<br />COURSE MANAGEMENT — all the tools of a modern course management system.<br />RESEARCH & COLLABORATION — project sites for research and work group collaboration.<br />SAKAIBRARY — Library-led component to add citations directly into Sakai.<br />PORTFOLIOS — Open Source Portfolio (OSP) is a core part of Sakai.<br />
  • 7. Defining Sakai: Community<br />COMPOSITION — educational institutions & commercial enterprises working in partnership with standards bodies & other open-source initiatives.<br />GOALS — work collaboratively to develop innovative software applications designed to enhance teaching, learning, research & collaboration in education.<br />VALUES — knowledge sharing, information transparency, meritocracy.<br />Educational Institutions<br />Standards <br />Bodies<br />Open Source<br />Commercial Affiliates<br />
  • 8. Sakai on the ground<br />200+ PRODUCTION/PILOT DEPLOYMENTS: From 200 to 200,000 users<br />
  • 9. Sakai on the ground<br />5 of top 10 Universities run Sakai<br />Stanford<br />Berkeley<br />Cambridge<br />Columbia<br />Oxford<br />#11 also runs Sakai (Yale)<br />
  • 10. Sakai on the ground<br />CTOOLS, University of Michigan<br />First production Sakai deployment, 2004<br />
  • 11. Defining Sakai: Code<br />OPEN LICENSING — Sakai’s software is made available under the terms of the ECL, a variant of the Apache license. The ECL encourages a wide range of use, including commercial use. <br />NO FEES OR ROYALTIES — Sakai is free to acquire, use, copy, modify, merge, publish, redistribute & sublicense for any purpose provided our copyright notice & disclaimer are included.<br />NO “COPYLEFT” RESTRICTIONS — unlike GPL redistributed derivative works are neither required to adopt the Sakai license nor publish the source code as open-source.<br />EDUCATIONAL COMMUNITY LICENSE (ECL)<br />
  • 12. Increasing Global Diversity<br />In 2006, 81% were in North America<br />
  • 13. Defining Sakai: Foundation<br />MISSION — manage & protect intellectual property; provide basic infrastructure & small staff; help coordinate design, development, testing & distribution of software; champion open source & open standards.<br />GOVERNANCE — ten board members elected by member reps to serve three-year terms; Executive Director manages day-to-day operations.<br />PARTNERS — over 100 member organizations contribute $10K per year ($5K for smaller institutions).<br />BUDGET — funds 4-6 staffers, admin services, computing infrastructure, project coordination, conferences, Sakai Fellows Program, advocacy & outreach activities.<br />
  • 14. Why Sakai?<br />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.<br />Stephen Marquard, Learning Technologies Coordinator, <br />University of Cape Town <br />
  • 15. Why Sakai 3?<br />Changing expectations<br />Google docs/apps, Social Networking, Web 2.0<br />Success of project sites = Sakai beyond courses<br />New technologies<br />Standards-based, open source projects<br />JCR (Jackrabbit)<br />Open Social (Shindig)<br />Client-side programming<br />JavaScript/AJAX<br />
  • 16. Sakai 3 Themes<br />Content Authoring and Management<br />Academic Networking<br />Breaking the Site Boundary<br />Academic Workflows, not (just) Tools<br />Sakai, Thick or Thin<br />Sakai Everywhere<br />
  • 17. Content<br />Content Basics:<br />Simple page creation (wiki-like)<br />WYSIWG Editing<br />Template-based authoring<br />Versioning<br />Interactive Widgets<br />Everything is content<br />Searchable, linkable, portable<br />Unified content repository<br />
  • 18. Sakai2<br />Site B<br />Site A<br />?<br />Finding something requires knowing which site it belongs to.<br />
  • 19. Sakai3<br />Tags: System, Organizational & User<br />Search + Smart Folders<br />
  • 20. Academic Networking<br />Content<br />People<br />Academic Networking<br />People are important, but “friends” aren’t enough<br />Content-based – Who is reading the same articles?<br />Activity based – Who has taken the same classes?<br />
  • 21. Sakai 2: Users & Sites<br />Site A<br />Site B<br />User 1<br />User 2<br />User 3<br />User 4<br />User 5<br />.<br />.<br />.<br />User N<br />User 1<br />User 2<br />User 3<br />User 4<br />User 5<br />.<br />.<br />.<br />User N<br />Group B1<br />Group A1<br />Users and groups exist within the context of a site.<br />
