3. xAPI – The People
3
‣ Authors – More than 30 authors to the spec,
approaching 100 contributors (via
discussion/support)
‣ Membership – 221 on the specification mailing
list, 55 registered on the weekly call
‣ Collaboration – Use Github, an online
collaboration site. Over 600 “issues” solved.
Anyone can register and then make a change.
The group then gets 3+ days to view it. If it gets
support by then and ADL approval, it becomes
part of the spec.
4. xAPI – The Specification
4
‣ xAPI hit version 1.0 in April 2013
‣ Stable and Interoperable
‣ As with SCORM, alphabet soup and gray area
‣ 1.0.3 this summer (I hope)
‣ A “tech spec for dummies” section
‣ No gray, no fuss, no muss
‣ Stars!
6. xAPI – The Conformance
6
• GitHub area
• Only test LRS (MUSTS)
• LRS ejects non-conformant content
• Testing requirement document
• Issues and classifications
• Software development to-date
– Two major test suite contributions
7. xAPI – The Roadmap
7
• Multiphase approach – 0 is SCORM, 1 is dual-track
(SCORM dominant still), 2 is SCORM optional, Phase
3= xAPI + any
• Suite of examples showing the Roadmap
• LMS to LRS synchronization, Server-side platform for
testing (modified SRTE), Dual-wrapper, library,
• Also LMS content call “Listener”
• At least one course for each Phase – real courses that
use the technology, at least 1 app, hopefully more
• Now until late summer
8. xAPI – The Profiles
8
• Profiles add definition to xAPI’s flexible nature
• CMI5 (Art) – inheritance from ADL
• SCORM Profile
• Need for both
• Intentional Synchronization
• First of many “ADL” COPs
9. xAPI – The Design
9
• Design “Cohorts”
• Free-to-participate group work to show off xAPI
• Pre-formed teams and interested individuals
• Build cool stuff like: Social Media Integration and
Expert Novice Analysis
• Currently in 3rd “Season”, led now by Craig
Wiggins, things like Augmented Reality, Ebooks,
Gameification, and Learning Analytics
10. xAPI – The Use Cases
10
• Do you hate the words “Out of scope” or “maybe
next version”?
• Do you have a use case that isn’t been met
because of some requirement?
• Do you have an xAPI use case that you haven’t
even looked into the technical requirements for
and can’t make that decision?
• Monthly meeting where anyone can be given the
floor to bring up issues or present use cases
