You're right, I made the dangerous leap from named graphs to the idea of 
'where you can get a graph representation'

(2) Named Graphs. It is a special RDF dataset, where the label 'l' is a (HTTP?) URI with an additional behaviour: if that URI is poked (GET-d) then it results in the serialization of a Graph whose parsing yields an equivalent graph to 'G'. It is the right/good framework for, say, Linked Data, etc.


It's always seemed to me that if someone owns the web address from which 
you can get a graph, that's a kind of provenance assertion.  Now I'm not 
sure about the relationship between HTTP and provenance, if there is any.
