  1. Interoperability and APIOpen, standards based architecture Bruno Van Haetsdaele Chief Architect

  2. The following is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality. The development, release, and timing of any features or functionality described for Wimba’s products remains at the sole discretion of Wimba.

  3. What is interoperability? ISO/IEC 2382-01 definition: “The capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units.” What is interoperability ?

  4. What does it mean for Wimba and our users ?

  5. How to achieve interoperability ? Impact: • User experience • Flexibility • Lower costs • Innovation Enablers: • Protocols • File formats • Standards • APIs • Open source Obstacles: • Patents • Trade secrets • Coordination failures

  6. Outline Outline Outline Education Web 2.0 Rich Media Collaboration

  7. Kiwi: a platform for the suiteGreater interoperability inside the Wimba suite • Wimba Voice into Wimba Create documents • Post a Wimba Classroom archive in the Podcaster • Associate a Voice Board to each Live Classroom • Education • Share • Unified management

  8. Kiwi Platform architectureOpen and scalable Admin AR CM pronto assess classroom voice Users Courses Member. Messaging Services (XMPP) Media Services (iax/vnc) Pronto Services Assess Services Classroom Services Voice Services Database File System

  9. Rich Media CollaborationBuilt using proven standards and projects • XMPP • Asterisk / IAX / SIP • Xiph Speex, Theora • MP3 audio for Voice, Classroom • VNC

  10. Leveraging the XMPP standards • XMPP is gaining momentum: • XMPP IETF approved standard since 2004 • GoogleTalk native protocol • AOL is experimenting with XMPP • Apple iChat supports XMPP • Wimba is extending XMPP for Pronto and Classroom • XMPP Federation

  11. Education standards • IMS Standards • LTI: Learning Tools Interoperability • QTI: Question and Test Interoperability • Enterprise • Common Cartridge • IA: Information Analytics • Advanced Distributed Learning: SCORM • Schools Interoperability Framework Associations

  12. IMS Learning Tools InteroperabilityWhat is the user need ? • Instructors and students: • Easy navigation from the CMS to external applications • Single sign on • Deep integration in the course • System Administrators • Easy deployment and configuration • Robust integrations • Software developers • More time spent in innovations, less in proprietary integrations

  13. Are these needs met today ?Wimba CMS Integrations… • .NET Portal components • C and Java Powerlinks • Java Building Blocks • Java Sakai portlets • PHP Moodle modules • Wimba APIs

  14. IMS LTI defines: Tool Producer contract Tool Consumer contract Web Services communication XML configuration Common CSS As easy as Facebook or Google Apps Learning Tools Interoperability

  15. IMS Learning Tools InteroperabilityWhat is the impact ? • Faster time to market • Easier to upgrade integration functionality • Increased robustness across versions of tool / cms • Less effort in developing integrations, more in innovation • Integration API for other CMS and more…

  16. Collaboration Reporting APIs for Information analytics • Capture: • Usage / Adoption • Course Context usage • Instructor/Student interactions • Measure • Social network inside the course / school • Collaboration index • Student engagement • Improve • Student retention • Learning Outcome

  17. Web 2.0 APIs for 21st century teaching and learning ?
