This went fairly smoothly, and resulted in the addition of several SCORM-specific database tables in addition to minor extensions to existing tables. All interactions and results are stored in the existing EDU 2.0 structures, which means it should be easy to integrate SCORM activities into the gradebook and assignment metaphor.
In the next phase I'll add support for student preferences and test out the integration with the gradebook. Things are getting close to a beta release!
This phase took 8 hours, bringing the total time to 37 hours.
