Identifying a particular object

> should I use two URLs?

graphs can (should?) have URIs. a good chunk to section off and give a "named graph" URI is the graph returned in a GET. in a crawler/aggregation scenario, one can then use the graph-URI as a subject-URI in RDF statements, for provenance or logging purposes

zooming out, formal definitions on sets of named-graphs http://www.w3.org/TR/rdf11-datasets/ and zooming in, on what sub-graphs should contain, http://www.w3.org/Submission/CBD/ 

> two URLs: the object URL and also the URL of the RDF file

a "file" is outside the scope of RDF. maybe you're using an in-memory quad-store, or key-val db - http://openmirage.org/blog/introducing-irmin perhaps

since a POSIX-style filesystem is fairly ubiquitous (on an Android/iOS phone, there's one in your pocket), it might be useful to talk about scenarios for using them to store RDF, but how you do it is up to you
