SPARQL-DL with OWL Functional Syntax

SPARQLAS is our implementation of the SPARQL-DL abstract syntax for writing OWL queries. With SPARQLAS, users write queries for OWL ontologies faster than using SPARQL, since they do not have to care about mapping OWL to RDF graphs.

Details

SPARQLAS queries are automatically translated into SPARQL queries that can be executed using an OWL reasoner and a SPARQL engine with support to OWL entailment regime, like pellet.
