I think here we want to point to a GraphContainer, i.e. a GRAPH in a SPARQL endpoint.

I'm now not sure if sd:NamedGraph is a Graph (in the RDF Abstract Graph sense) or a GraphContainer (in the INSERT INTO GRAPH sense).

This is the source of the problem that I try to treat in the URLs I just sent you.

is a slightly "from scratch" perspective on the problem of "getting at" a named graph hidden behind a SPARQL service.


http://www.w3.org/2011/prov/wiki/Using_named_graphs_to_model_Accounts
wrestles with the different meanings of "named graph" - one of which is the RDF 1.1 WG's GraphContainer (that currently doesn't have a standard way to identify)
