Correct. > How can I get > `sdbquery` to use OWL semantics? In principle you could define your model as an inference model running over SDB by creating a suitable assembler description and using arq.query (which can be passed an assembler file). However, running the Jena OWL reasoners over a database of any significant size will be horribly slow. One alternative would be to compute an OWL closure of the data before your load it into SDB.
