Open/Open Licensing
• “..all work products under the scope of the Sakai initiative for which a member is counting matching contribution and any Mellon Sakai funding” will be open source software and documentation licensed for both education and commercial use without licensing fees.
Sakai Community Support
• Developer and adopter support – Sakai Educational Partner’s Program (more below) • Commercial support – No exclusive deals – talk with everyone – Open-open licensing – open source, open for commercialization – For fee services will probably include… • Installation/integration, On-going support, Training
Sakai Educational Partner’s Program
Fee: $10k per year, 3 years
• Access to SEPP staff – Community development manager – SEPP developers, documentation writers • Knowledgebase • Developer training for the TPP • Exchange for partner-developed tools • Strategy and implementation workshops • Early access to pre-release code
SEPP Support
• Developers to provide technical support for partners and liaison with the Sakai Core development team, • Support tools of immediate and specific interest to partners, such as a shared knowledgebase, • Technical documentation and specifications, • Administrative Support person to aid SEPP staff members and partners.
SAKAI Partners
“institutions of higher education, both large and small … participating in the Sakai Project in ways that suit their local needs and timing. These may include: – contributing to funding the project to ensure an open source option for higher education, – participating in the discussion of strategic directions for the Sakai Project – developing educational tools based on Sakai’s Tool Portability Profile, and/or – adopting Sakai Project software at their institution.”
SEPP Objectives
(1of 3) The objectives of the Educational Partner’s Program are to: • actively develop a large, self-sustaining community of institutions that share the Sakai Project’s open source vision • carry on a discussion of strategic directions for the Sakai Project as it emerges and evolves, • provide a Sakai Project roadmap describing the timing and features for Sakai software releases,
SEPP Objectives
(2 of 3) • provide in depth developer and adopter training, • develop a leveraged support infrastructure of a common (or locally implemented) knowledgebase, and helpdesk • mobilize distributed resources for development and support of Sakai tools, • provide a marketplace for the sharing and exchange of Sakai-based tools/components, • facilitate purposeful interaction with the Sakai Core development team,
SEPP Objectives
(3 of 3) • coordinate activities with other organizations, such as IMS or country-level agencies, • build on the experiences of the JA-SIG, CHEF, and OKI training and conferences, • facilitate Sakai community sharing of best practices in development, implementation, and support.
SEPP Meetings
• The initial SEPP meetings are planned for June and September of 2004. • The semi-annual SEPP meetings will have a technical track for training software developers and implementers and an administrative track for Sakai strategy and user support. • Partners may send two developers to each meeting for formal training in the Sakai Tool Portability Profile by the lead technical staff of the Sakai Project.
What Can Be Done Now - Look At:
• www.sakaiproject.org
• uPortal (www.ja-sig.org) • JSR 168 • Chef (www.chefproject.org) • OKI (web.mit.edu/oki) • J2EE/EJB/JBoss – Tools won’t be built this way, won’t even see EJB’s – Services
should
be built this way • Clustering, scaling, caching, cache coherency – rely on entity beans • Avalon, Spring, Pico – Inversion of Control models – Levels 1,2, 3 – Loader models
What should we be doing here at UVa?
• Start a regular series of discussions • Become familiar with the various pieces and technologies in the Sakai project • Get plugged into the Sakai project • Start planning how to take advantage of Sakai – Assess existing Toolkit functionality versus Sakai, e.g., what to keep, what to replace – Start designing the ToolkitNG based on Sakai – Envision and design the larger MyUVa that includes ToolkitNG

Tool Portability Profile
• The Open Knowledge Initiative’s (OKI) OSIDs OKI Service Interface Definitions • The JSR-168 portlet specification –
Built into Michigan’s CHEF and
–
JA-SIG’s uPortal
• User interface abstraction for localization
uPortal JSR 168 Portal CHEF Provides the place for the tools to run, the services, and communication between them.
CHEF JSR 168 Portlet Container uPortal talks to portlets, aka tools, across the JSR 168 interface, aggregates their content, and presents their content to users. Tools use the services (storage, notification, workflow, …) made available to them by the framework.

JSR-168 Instant Tutorial
• JSR-168 leverages the Servlet API – anything Servlet references, JSR168 just adopted • The concepts of actions and context are there (basic MVC with some separation of logic and presentation)(enough C that you can do M&V separately) • Great support for JSP as rendering language, or the portlet could choose to call Velocity or XSLT to do the rendering.
• The API is very rich and solves many of the complicated problems of living inside of a portal. • WSRP and JSR-168 are well aligned (i.e. remote and local portlets will play well together) • There is a Jakarta project to develop JSR-168 middleware (Pluto) • Pluto does not implement a portal – it can be used by many portals, that’s the portlet container concept, and one of the main points of 168 • So, we really like JSR 168
Some Standards
• OKI – services interfaces • JSR 168 – portals, portlet containers • SCORM – looking for someone to build portlet, service – interchange format - zipformat, manifest, etc; runtime environment - pop-up frame set, database-persistent scratch space – island? Out of band agreements need to be codified for integration into Sakai • LOM – Looking at it, like IMS standards • IMS – where applicable, like QTI for assessment – Increasingly coordinated with OKI efforts – what/how – Emerging effort for common architectures • XML/XSLT - sure, as part of, say, QTI spec, or for display rendering • RDF – of increasing interest to Chef team – stay tuned
Chef Project
• Encompasses CT.NG, WT.NG, NeesGrid, NMI, other users of Chef • Is the core software development effort – Providing framework for tools that go to make up the other offerings, eg, CTNG, WT.NG, DissertationTool (
cTools
) • We are currently running Chef 1.2 for CT.NG
• Chef 2.0 is foundation for Sakai

The OKI Initiative
• The Open Knowledge Initiative™ is a collaboration among leading universities and specification and standards organizations to support innovative learning technology in higher education.
• The result of this collaboration is an open and extensible architecture that specifies how the components of an educational software environment communicate with each other and with other enterprise systems. O.K.I. provides a modular development platform for building both traditional and innovative applications while leveraging existing and future infrastructure technologies.
• O.K.I. is designed for broad adoption in the higher education domain. It provides a stable, scalable base that supports the flexibility needed by higher education and commercial developers of educational software.

OKI - What Can be Done Now?
• • Enterprise systems developers/managers should familiarize themselves with Version1.0rc6.1 of the O.K.I. OSIDs http://sourceforge.net/projects/okiproject • All the JavaDoc, Developer Docs, Reference Docs, Solutions Guides as well as reference code and other developer aids can be found there.
OKI - What Can be Done Now?
• Begin developing implementations of appropriate OSIDs to integrate with campus systems • The O.K.I team and others actively scan and respond to issues that are raised on the SourgeForge OKI project forums. Developers should be encouraged to post questions/issues/gripes/etc.
OKI - What Can be Done Now?
• In many cases there will be opportunities for institutional collaboration, especially where common technologies are in use: – LDAP/Kerberos etc. for AuthN – PeopleSoft for Student Information Data – CorporateTime/Meeting Maker/etc.
– AFS for campus file systems – Etc…
Sakai Educational Partners Program
• Initially the SEPP can provide developer training opportunities as well as help in coordinating common OSID implementation efforts across member institutions.
