SPARQL is the W3C recommendation for query answering in the Semantic Web. TrOWL v1.0 treats SPARQL variables as distinguished variables that can be evaluated as individuals. TrOWL v1.0 supports the usual TrOWL API and the TrOWL-BGP API. The usual TrOWL API can be used alone in a same way as previous TrOWL releases. To support SPARQL query answering, both TrOWL and TrOWL-BGP are needed.
