Correct.

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.
