OntoSelect provides an access point for ontologies on any possible topic or domain that is automatically updated, organized in a meaningful way and with automatic support for ontology selection in knowledge markup. Unlike for instance the DAML and SchemaWeb ontology libraries, OntoSelect is not based primarily on a static registration of published ontologies, but includes a crawling procedure that monitors the web for any newly published ontologies in the following representation formats: RDF/S, DAML or OWL.

RDF Schemas are the critical layer of the Semantic Web. They provide the semantic linkage that 'intelligent' software needs to extract value giving information from the raw data defined by RDF triples.
