Abstract: In this paper we present our implementation of an OWL 2QL reasoner using query rewriting to answer SPARQL queries in a relational database. To answer queries in the database through rewriting, ontolo- gies are limited to the OWL 2QL profile. The rewriting algorithm inter- nally produces a non-recursive Datalog program from the given SPARQL query. This program is then translated to SQL and executed by the database.
