OntoBroker

Comment	Ontobroker exploits knowledge models and data from different sources to answer queries. For that purpose it evaluates axioms contained in the knowledge models to derive new knowledge or to check the consistency of the available knowledge. It runs as a middleware system and thus may be used by a variety of applications of our product partners and customers as an information delivering base. Ontobroker is already used by the W3C as a reference implementation (SiLRI) for an inferencing tool for Semantics for the Web.
