Hey,
the datamanager is great. Regarding cards I just wonder how it is related to the evaluation package.
Also SIUVADIM seems interesting though I was not able to see the UI. There is an ims-ent package that partially implemented the IMS Enterprise Specification. I think Rocael was the one who wrote that. It has an XML binding for the elements enterprise, group, user, membership. Maybe we can integrate your work by extending the ims-ent package. The only question is how to map subjects, classes.
Greetings,
Nima
