Document Model Feedback

Current Model: Master Data Model Documents

Cardinalities are missing

Subresource object should have a link to the version object not to the document object
- Link will be changed, so subresources can be defined for different versions of a document
Should ACL have a link to version instead of object?
- ACL has a link to object to cover different cases e.g. giving permissions for a complete folder (would not be possible if ACL has a link to version instead of object)
Meaning of relation?
- Relation is meant to describe the relation between two documents e.g. order and invoice
