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