1. Sponsored by the Office of the Under Secretary of Defense for Personnel and Readiness (OUSD P&R) xAPI Specification Working Groups Andy Johnson Contractor with Problem Solutions, LLC in support of the ADL Initiative I/ITSEC Plugfest 3 December 2014 Orlando, FL

2. History 2 ‣ xAPI transitioned to ADL in 2012 as version.80 of what was called “TinCan” ‣ Did work following the BAA and it was updated to.90 ‣ At this point in time the working group was established, releasing.95 in October 2012 and 1.0 in April 2013 ‣ Version 1.0.1 was formalized and released in Oct 2013 (clarification and intended 1.0 changes only) ‣ Informal 1.0.2 and 1.0.3 (no breaking changes)

3. Open Source Benefits 3 ‣ Security and Quality – The more people who see the code, the more likely flaws will be caught and tested quickly ‣ Freedom and Customizability – With all of the code available, any custom updates can be made without vendor reliance ‣ Auditability – Visibility of code means that systems can be verified first-hand ‣ Costs – Licensing costs are low or free ‣ Support Options – Vibrant communities with forums, wikis, newsgroups, chat, etc.

4. Membership and Process 4 ‣ 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 500 “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.

5. Technical Writing Specification Group 5 ‣ Carefully wordsmiths the technical specification requirements to be as clear as possible ‣ Spec requirements feed into Conformance Testing (Part of this group’s responsibilities) ‣ Also adding best practices, some of which the group has agreed will become requirements in version 2.0 ‣ Striving to maintain backward compatibility ‣ Use GoToMeeting, but also have DCO for our.mil colleagues

6. Use Case and Implementation Group 6 ‣ Focuses on present and future implementation decisions of xAPI, targeting version 2.0. ‣ Use cases discussed and explored ‣ Sweeping changes in the name of industry best practices or universality are also discussed ‣ Anyone in this group can sign up to present or pitch a 2.0 change
