OntoBroker RDF is an RDF triple store, query and inferencing engine. It is well integrated into the general OntoBroker suite, allowing close interaction between the other supported knowledge representation formats OWL and ObjectLogic. Staying close to the official Semantic Web standards like RDF, RDF Schema, and SPARQL is one of the primary design goals. However, the implementation on a horn logic-based model imposes some restrictions in standard compliance -- and some unique features too. This document will give a pragmatic overview of OntoBroker RDF, focusing on RDF-related options and features. For more general issues, see the provided locations in the main OntoBroker documentation.
