Agenda approved. There are no minutes from the last meeting.
General LETSI News
PPWG is preparing Operating Procedures for SEC approval. Individual and organizational memberships are planned.
A full-day LETSI meeting is scheduled for March 13 in Seoul. LETSI will also participate in the Open Forum on the next day. The SC36 SCORM Study Group will meet on the 16th. LETSI's liaison with SC36 will be discussed on the 21st.
Notes from the AICC meeting last week in San Jose
Over 50 people participated. A briefing about LETSI was included in the first day's program. LETSI sees the AICC as a mature community of practice with advanced technical needs.
Microsoft has developed a simulation development platform based on Flight Simulator. They are interested in defining standard interfaces between learning systems and simulations/games.
The ADL is working with the AICC on the Content Services Architecture, which is looking at web service definitions for learning systems. The group is also exploring requirements for content delivery and catalog services, but the eventual scope of the effort is not yet defined.
BBN's web services definition for the ECMAScript API could be added as an annex to the spec in its 5-year review at IEEE. This should be brought up at the IEEE LTSC meeting in April.
CTC presented the use of "state transition diagrams" as a way of programming complex graphics. There is an XML language being developed at W3C. This could be used as a general-purpose solution to sequencing. Further exploration is planned. Also LETSI will eventually be surveying various approaches to sequencing as we better understand requirements for SCORM (Kiyoshi, IAI, BPM, SCORM templates, web service orchestration, ...). Perhaps a workshop would be useful in the future.
AICC/ADL/LETSI Joint Content Aggregation Workshop
About 20 people attended the workshop on the day after the AICC meeting, including AICC members and folks from, ADL, Adobe, Moodle, SkillSoft, .... Several submitted position papers were presented and discussed. DITA and S1000D were discussed as alternatives, as well as MPEG and IMS Content Packaging.
The AICC expressed interest in adopting an XML approach, but are very concerned with backwards compatibility and extensibility. Also want integration with CSA, PETS, and offline CMI.
The notes from the Workshop as well as the position papers will be posted on the TRWG wiki. We will go forward with requirements gathering and exploring technical alternatives. Additional meetings might be useful, e.g. and ADL/DoD Content Aggregation Workshop.
Framework Document
Discussion: How do we gather requirements and explore technical alternatives in parallel? How do we decompose the functional requirements from SCORM 2.0 and the future-state learning environment? How broad a net do we want to cast?
Clark will prepare a white paper discussing functionality definitions and architectural alternatives at a higher level, which we'll discuss at the next meeting.
We should explore the requirements worked out in the IEEE RAMLET group.
