SAIQL (Schema And Instance Query Language) is a novel query language for OWL DL. In contrast to existing query languages like SPARQL or OWL-QL, SAIQL is capable of querying the T-Box and the A-Box in an integrated manner. Furthermore, SAIQL is aware of OWL DL semantics. SAIQL is well suited for ontology extraction and re-use.

As soon as possible, will publish further material about SAIQL here. We have also started to implement a first query engine for SAIQL. After finishing it, it will be available for download here.
