Description First, we discovered that ontology-based data access (OBDA) with the W3C standard OWL 2 QL can be prohibitively expensive in the worst case. On the other hand, we demonstrated experimentally that, in real-world practice, OBDA is very efficient.
Exploitation Route The OBDA system Ontop is open access.
