If the modeling in the example section[1] works for the named graphs you're hoping to describe (the named graph pointed to by the sd:namedGraph property), then the new class will probably be what you're after.

I wonder if it would owl:equivalentClass the rdfg:Graph.
Ontology mapping is important or the main advantage of RDF over XML and
such is lost. I guess no W3C standard did that yet.

Anyway the RDFG has prior act. I wonder if we as a group of people
interested in Semantic Web could come up with etiquette for ontology
mapping.
