We describe an approach to building a Semantic Web resource protocol-a scalable, extensible logical addressing scheme and transport protocol-by using and extending existing specifications and technologies. We introduce XPointer and some infrequently used, but useful features of HTTP/1.1, in order to support addressing and server side processing of resource and subresource operations. We consider applications of the XPointer Framework for use in the Semantic Web, particularly for RDF and OWL resources and subresources. We describe two initial implementations: filtering of RSS resources by date and item range; RDF subresource selection using RDQL. Finally, we describe possible application to the problem of OWL imports. 1 RDF, RDFS, and OWL RDF, RDFS, and OWL form the middle layers of the so-called Semantic Web layer cake. They are also its transitional layers; the parts beneath RDF-RDFS-OWL are part of the existing Web and are not distinctively semantic. These lower layers-URIs, Unicode, XML, and W3C XML Schema (WXS)-are not KR formalisms, though they do contribute, especially XML and WXS, to the syntax and the semantics of RDF, RDFS, and OWL.

They often have to be distinct for legislative and other policy reasons. These separations are not clean and are often fractured. And there's no reason to believe that any particular KB is authoritative or complete with respect to the whole knowledge domain. Finally, each knowlege base has both an independent history and provenance, but also, often, independent schemas and underlying implementation techniques.
