In that case, let me reply :-)

I was not really expecting anything in particular: data, metadata, or 
both. The background of my question is that I am trying to use a quad 
store, but I do not know how it should behave in this respect. Has 
Virtuoso made a decision on the matter?

I can understand the option of returning a description of the graph, 
instead of its triples. In that way a named graph would behave like a 
data set, which is another collection of triples. I am sure the RDF WG 
is fully aware of the pros and cons of all options and I wish them much 
wisdom in finding a solution for the problem. For me things have become 
clearer. I did not know that the issue is still in debate.

Regards,
Frans
