Interface to content repository

OpenACS Content Repository (CR):
  • Distinction between content-item and content-revision
  • Updates are revisioned
  • Most attributes are stored in the revisions
  • Content-items and content-revisions are acs-objects
  • Content-items are named entries, unique per parent_id (e.g. folder)
  • Extend attributes via subtyping/subclassing 
  • Single XOTcl layer, accepting either item_ids or revision_ids
