My rationale for this is that (b) is an intermediate construct that is used to explain the linkage between (a) and (c), but in general (as far as I'm aware) has no visibility exposed via Web architecture other than (c). Example. Suppose we have an RDF file describing zebras: (r1) http://example.com/zebras.rdf which contains statements referring to URIs (r2) http://example.com/zebras/#zebra1 (r3) http://example.com/zebras/#zebra2 Provenance information about (r1) would be an instance of (c) - noting that in this case it would relate to the state of multiple resources. Provenance information about the referents of (r2) and (r3) would be an instance of (a) - where they were born, who were their parents, etc. (I can imagine situations in which one explicitly constructs and identifies a notion of resource state (e.g the state of health of a zebra), but I'd see that as a special case constructed by an application, not part of the general Web model. But even in such a case, what would it mean to refer to the provenance of an animals state of health, as opposed to a record (representation) of its state of health?) #g -- > On 05/20/2011 08:00 AM, Provenance Working Group Issue Tracker wrote: >> PROV-ISSUE-1 (define-resource): Definition for concept 'Resource' >> [Provenance Terminology] >> >> http://www.w3.org/2011/prov/track/issues/1 >> >> Raised by: Luc Moreau >> On product: Provenance Terminology >> >> The Provenance WG charter identifies the concept 'Resource' as a core >> concept of the provenance interchange language to be standardized (see >> http://www.w3.org/2011/01/prov-wg-charter). >> >> What term do we adopt for the concept 'Resource'? >> How do we define the concept 'Resource'? >> Where does concept 'Resource' appear in ProvenanceExample? >> Which provenance query requires the concept 'Resource'? >> >> Wiki page: http://www.w3.org/2011/prov/wiki/ConceptResource >> >> >> >> >> >
