SPARQLAS - Implementing SPARQL Queries with OWL Syntax.
Mark Schneider · 2010
Abstract. Using SPARQL for writing queries on OWL-DL ontologies can be complicated due to its RDF triple semantics. Translating OWL expressions to this semantics is a non-trivial problem. We present SPARQL-DL Abstract Syntax (SPARQLAS), a proper subset of SPARQL, to solve this issue by employing the OWL Functional-Style Syntax to compose queries. We illustrate how the translation is made possible by a modelto-model transformation and how a query can be connected to an UML model. Finally, we evaluate SPARQLAS against SPARQL and show the efforts of SPARQLAS for queries on OWL-DL ontologies. 1
