Question:

• If a user has no right to create a collection (can not upload), can another user give him the right to upload within one collection?
• Does it make sense not to be able to create an Album?
• An admin role with all rights is missing? (could then do things which are not possible with normal rights, like delete pubished objects)
• What means 4?
• For collection/album is share = edit = publish ?
• Edit item = edit item metadata? if yes, then is missing edit profile, i.e. add/remove md in profile
