I am content with how the following statements address the relation between DM literal and RDFS Literal:


" A PROV-DM Literal represents a value whose interpretation is outside the scope of PROV-DM. "

"In particular, a PROV-DM Literal may be a URI-typed string (with datatype xsd:anyURI), or URI-denoted resource (with datatype rdf:Resource); in either case; such URI has no specific interpretation in the context of PROV-DM."




The language and datatyping grammar seems a bit excessive, but I have no objections.

Regards,
Tim
