Re: Contexts (spinoff from copy and wrap rdf statement I still prefer to think of the resource being the information, and any particular document being a representation of the resource. For example, say <http://example.org/privacy> is the URI of a company's privacy policy, which might be available in multiple languages and formats and might vary over time. The actual bytes which you would receive (the representation) will vary, but the resource is constant. Put like that I would probably agree with with you. But I was really trying to get an idea of how best to deal with a particular kind of representation, the RDF document. Similarly, I would think of <http://somewhere/me.rdf> as being a dataset which can be expressed in terms of triples. Any RDF documents you get as a result of dereferencing the resource would be representations. But how are those representations to be interpreted? If the RDF document at http://example.org/c.rdf contained the triple: Sassi hasSpecies Cat and (elsewhere) I asserted http://example.org/c.rdf is true would I be saying simply Sassi hasSpecies Cat or http://example.org/c.rdf says "Sassi hasSpecies Cat" ? This is rather an artificial example, consider a more realistic example: http://example.org/c.rdf dc:Creator Sambuca What does that mean in terms including the triples found in c.rdf? Is it equivalent to the statements: { http://example.org/c.rdf dc:Creator Sambuca Sassi hasSpecies Cat } or { http://example.org/c.rdf contains S1 S1 subject Sassi S1 predicate hasSpecies S1 object Cat } If you needed to refer to an actual RDF/XML document that you downloaded at a specific time, you could use something like: _:a rdf:type eg:Representation; dc:source <http://somewhere/me.rdf>; dc:format "application/rdf+xml"; dc:language "en"; dcq:issued "2002-11-23t10:30:00z". This is certainly useful, but it doesn't deal with the issue above. Cheers, Danny.
