But in the context of the appropriate RDF schema, rdf:type *is* an XML element, no? Test case: In Web-retrieval of the application/rdf+xml document: http://www.w3.org/1999/02/22-rdf-syntax-ns I think that http://www.w3.org/1999/02/22-rdf-syntax-ns#type refers to this XML element: <Property ID="type" s:comment="Identifies the Class of a resource" /> (possibly with some namespace decorations...?) >(dragons, dragons, dragons, dragons!) Yes, I suppose, dragons. For me, this is helping to clarify the distinction between fragment-ids used in web retrieval, and fragment-ids used in RDF resource identifiers. In the latter use, I think that: http://www.w3.org/1999/02/22-rdf-syntax-ns#type denotes a resource with a relational extension corresponding to the class membership of RDF resources. Or, as you put it, the concept of type. Which has only tangential relationship to the indicated part of the indicated RDF schema document. In writing this, I'm clinging to a clear terminological distinction: referring, or reference, in the Web denotation, a semantic concept ... So, returning to my proposed wording, I'll suggest an revision: [[[ Given a URI that dereferences to an application/rdf+xml document, that URI with a fragment identifier refers to an XML element in the document having the given fragment identifier for its rdf:ID attribute value. ]]] #g ------------------- Graham Klyne <GK@NineByNine.org>
