Semantic Web - (loosely) the idea of incorporating semantic information in the WWW, so it becomes machine understandable (rather than just parsable). CWM is Tim Berners-Lee's (and others) tool to handle ontologies. I think it has some rules in-built, but for reasons of efficiency, most ontology tools communicte with external Description Logic Reasoners via the DIG (Desc. Logic Implementation Group) interface, which is http/XML based. Much of the semweb stuff is OWL (Web Ontology Language - need to be a Winnie The Pooh fan to get the acronym) based. OWL is a layer that lies on top of RDF (which in turn, lies on top of XML). In general, yu build an ontology in OWL, and then interface with a reasoner to infer more info. about the model. The two big ontology building tools are Protege (with the Protege OWL plugin) and SWOOP, but both are Java based. HTH. Matt -- Dr. M.
