Re: Contexts (spinoff from copy and wrap rdf statements)

Re: Contexts (spinoff from copy and wrap rdf statementI would consider the set of statements in a document (or graph) to be a property/value of the document (or possibly a "part", but I think that's an unnecessarily complicated viewpoint).  Now you can talk about that property/value, define a truth-value property for it, etc.

    If you let a resource refer to itself, you can just say
        resource has
            graph = "...",
            document = "..."
    (however you want to say it in RDFS)
    so the graph would have a reference to itself and the document,
    and ditto for the document.  

    Having such a "cross-reference" doesn't cause any problems, does it? 

    Probably not. 

    Aren't the graph and document "isomorphic", i.e., logically equivalent, or
    are you talking about a different kind of document here?

    Hmm - that's the crunch I suppose. A HTML document can be a resource and have a URL that can be used as its URI. But do we consider an RDF document in the same circumstances a closed box, or a bunch of 'free' statements..? Similarly, if the HTML doc (let's make that XHTML+XLink) made RDF-friendly statements ("myMetaDataHere: me.rdf") how available to the referrer should those statements (and anything else they refer to), be? 

    I guess this is back into the "dark triples" idea.

    If statements are directly asserted by this then they lose their provenence, if they are quoted/reified then that brings up the question of unquoting/unreification mechanisms.
    Hmm... 

    Cheers,
