SPARQL-DL Implementation Experience.
Petr Křemen, Evren Sirin · 2008
Recently, SPARQL-DL was introduced in [7] as a rich query language for OWL-DL ontologies. It provides an OWL-DL-like semantics for SPARQL basic graph patterns which involves as special cases both conjunctive ABox queries and mixed TBox/RBox/ABox queries over Description Logic (DL) ontologies. This paper describes the implementation of a SPARQL-DL query engine and discusses several optimizations. We investigate the new challenges brought by the additional expressivity of SPARQL-DL by extending a well-known benchmark.
