There is an inverse of rdfs:isDefinedBy [1].

Here's some easy to read SPASQL (SPARQL + SQL) showcasing the use of 
rdfs:isDefinedBy, wdrs:describedby etc..

INSERT INTO <http://www.semanticdesktop.org/ontologies/2007/03/22/nco/>
{?s rdfs:isDefinedBy 
<http://www.semanticdesktop.org/ontologies/2007/03/22/nco#> .
<http://www.semanticdesktop.org/ontologies/2007/03/22/nco#> 
<http://open.vocab.org/terms/defines> ?s.
<http://www.semanticdesktop.org/ontologies/2007/03/22/nco#> a owl:Ontology .
?s <http://www.w3.org/2007/05/powder-s#describedby> 
<http://www.semanticdesktop.org/ontologies/2007/03/22/nco/>}
FROM <http://www.semanticdesktop.org/ontologies/2007/03/22/nco/>
WHERE { optional {?s rdfs:subClassOf ?o}. optional {?s 
rdfs:subPropertyOf ?o}. optional {?s owl:equivalentClass ?o}. optional 
{?s owl:equivalentProperty ?o}. optional {?s a ?o}} .
