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.
