Project Tsugi • Tool Hosting Container (i.e. Like a B2) – PHP now, Java planned • Based on IMS Specifications – LTI 1.x / LTI 2.x / IMS Settings / Common Cartridge / Caliper / CASA / Roster / Gradebook / .... • Tools can run on a campus hosting platform or commercial provider or cloud • Tools are "installed" into hosting containers

- 9. "Large Midwestern University" Sakai ....... Looks pretty cool.... But...
- 10. Sakai • Where is the user data?? • What happens when there are 50 apps? • What if the app is free and hosted by a professor? • What happens if we stop paying the license?
- 12. LTI 1.x versus LTI 2.x and Beyond • LTI 1.x – Three pages of spec and some "hello world" code • LTI 2.x – Several specs – multiple interactions – We will need to share common implementations across instructions • And what about Caliper, Casa, xAPI, etc. ??

- 24. PHP Tsugi Next Steps • Architecture Review / Critique • Internationalization – need help • Outreach to the Moodle community • IMS LTI 2.0 Support • xAPI support • IMS Caliper Support • IMS Casa Support Tsugi is in 24x7 production and I can support a few experimenters on my servers.
- 25. Java Tsugi Dreams Sakai Sakai Tool Sakai Blackboard B2 Tool B2 I am not in a rush to do the Java port. I want to stay agile and use PHP as an architecture proof of concept. The Java port will be simple and fast with PHP in hand.
- 27. Thinking Big... • I hope to bring TSUGI to Apereo Incubation before next conference • I would like to build a tool ecology to benefit all teachers regardless of LMS • I want us to own our data and cloud choices • I want to see Blackboard, Moodle, Canvas, and D2L schools joining Apereo
