Current SCORM implementation
Lesson-Server communication based on AICC API (appendix B) mechanism
This allows each vendor to specify browser server communication
Requires parent/navigation frame to host API
Some AICC calls have been slightly modified
AICC data like "Paths" has been entirely removed. Some capabilities were not supported by any LMSs, but in the future they may be missed.
Course Structure File uses IMS 1.1 directly
Less structural information than AICC
More per-file information
Specification suggests creating an archive in zip format for transfer of the course - this is very useful.
