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 believe it would be hard to have the SD document reference an ontology that isn't a standard. This is already the reason it's difficult to talk about serializing quads in things like SPARQL as I don't believe any of the formats are properly standardized (TriG, TriX, N-Quads). I'd be happy to see linking happen *to* the SD terms, but I'm doubtful that the SD document could link to external terms.

That being said, if you'd like to make an official comment on this topic, please do send a message to public-rdf-dawg-comments@w3.org, and the working group will address it formally.

thanks,
