Hi,
The data model (level A) has been normalized (http://cvs.openacs.org/cvs/*checkout*/openacs-4/packages/imsld/www/doc/ch04s01.html), and some errors found in the spec where fixed.
Please let us know any comment or suggestion (specially identifying which tables can be modeled using acs_objects or items).
We will now focus on the API, and let the normalization/optimization of the data molels of levels B and C for later, after we support level A.
Regards,
Jose Pablo
