Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

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. |
