Abstract: |
RDF(S) constitutes a newly emerging standard for metadata
that is about to turn the World Wide Web into a
machine-understandable knowledge base. It is an XML application that
allows for the denotation of facts and schemata in a web-compatible
format, building on an elaborate object-model for describing
concepts and relations. Thus, it might turn up as a natural
choice for a widely-useable ontology description language. However,
its lack of capabilities for describing the semantics of concepts
and relations beyond those provided by inheritance mechanisms
makes it a rather weak language for even the most austere
knowledge-based system. This paper presents an approach for
modeling ontologies in RDF(S) that also considers axioms as objects
that are describable in RDF(S). Thus, we provide exible,
extensible, and adequate means for accessing and exchanging axioms
in RDF(S). Our approach follows the spirit of the World
Wide Web, as we do not assume a global axiom speci cation
language that is too intractable for one purpose and too weak
for the next, but rather a methodology that allows (communities
of) users to specify what axioms are interesting in their domain.
