[an RDF lurker writes...] That also seems broadly consistent with RDF's use of 'reification' to create representations of RDF triples/statements. Perhaps the main difference is that the RDF Model+Syntax spec only talks about the reification of RDF statements, and not about people/places/topics etc. One problem we have (for RDF anyway) when trying to articulate a broader notion of reification is then in deciding where we draw the representational line between 'computable/addressable' objects and those objects that need to be represented via a proxy / stand-in resource. People don't tend to have URIs; mailboxes do. Physical books don't; whatever-it-is-that-URIs-name do. And so on. If our crititeria for deciding when to call it 'reification' is related to our ability to use a URI name for the object directly, the distinction seems somewhat fragile and time-sensitive. Perhaps that's why RDF sticks with a more restrictive use of the term 'reification', only applying it to the reification of statements. Don't know if this helps, but thought I'd chime in with an RDFish perspective. cheers, Dan ------------------------ Yahoo! Groups Sponsor ---------------------~-~> eGroups is now Yahoo!
