Re: PROV-ISSUE-520: Data Model Section 5.3.1 [prov-dm]

I agree as well. Is there really a difference between prov:Person and
foaf:Person?
I think it would be nice to add in the FAQ something like prov:Persons are
always responsable
for something, while foaf:Persons don't have to be.

Best,
Daniel.
