Hello all,

I think it should be distinguished between the user roles regarding the 
resource, and the user roles regarding the represented object.
Thus, the three kind of applications or roles defined by the 
metadataworkinggroup (creator/changer/consumer) operate on the resource 
but may not match logically the role regarding the represented object.

For example, the word "creator" is somewhat ambiguous because it may 
refer to the role which creates materially the resource, or to the 
actual artist which conceives an idea. Both "creators" do not 
necessarily match. Have you thought about it?
