To clarify, the resource can be a document that contains a schema definition or rdfs:Class which corresponds to the definition of "object". In RDF schemas, class properties are themselves first class objects and hence can be defined outside of the class definition, e.g. in distinct documents. URIs are used to define types, not just instances: e.g. these statements assign types to instances (note the instances themselves need not contain RDF): <rdf:Description rdf:about="http://www.wherever.com/foo1_instance.xml"> <rdf:type rdf:resource="http://example.org/foo1.rdf"/> </rdf:Description> <rdf:Description rdf:about="http://www.wherever.com/foo2_instance.xml"> <rdf:type rdf:resource="http://example.org/foo2.rdf"/> </rdf:Description> Jonathan Borden The Open Healthcare Group http://www.openhealth.org
