Re: PROV-ISSUE-532: Data Model Section [prov-dm]

Hi ,

I suggest the following response.

The Working Group has given careful consideration to roles in PROV. We 
allowing roles in all relations. A problem with such a permissive 
approach is that it is not
clear who is playing the role. For instance, if a role is added to 
delegation, which agent is
assuming that role: the delegate or the responsible?  For the example of 
delegation, the group
suggests using the attribute "prov:type" if a subtype of the relation 
needs to be specified,
e.g. contractual delegation.

For a history of the debates: see
For a group resolution on this matter: see:
For the final definition: see

Proposed changes: none.

Thoughts? Comments?
