Demonstration of the Quest query engine for SPARQL over relational databases. Quest supports OWL 2 QL and RDFS inferences over live relational databases by means of query rewriting. The performance of Quest is often dramatically better than similar tools like D2RQ and Virtuoso. • NOTE: Since 2015, the syntax ontop mappings has changed. Follow the following link for information on the updated syntax: https://github.com/ontop/ontop/wiki/T... • Also, ontop now can import and export mappings in R2RML syntax.
