Can one of you create a ticket for this? The solution of this is probably
not within the scope of this task, but this should be resolved.

> If a predicate has an *{{rdfs:domain}}* of some class, than the subject of
> any triple including that predicate belongs to the class.
> If the ontology states that {{:advisor}} has the domain of {{:Person}}, then
> the inference engine should rewrite queries of the form {{?x rdf:type
> :Person}} to check for resources which have any {{:advisor}} (as well as any
> specifically stated to have type {{:Person}} ).
