updating parts of an ontology

["Bahador(reza)? OFOGHI" <br...@yahoo.com>]

Hi,
 
I have a super ontology that includes some sub-ontologies with a subClassOf relationship between a node of the super ontology and the root of the sub-ontology in each case.
 
My question is: if I want to update a sub-ontology, can I remove() the root of that sub-ontology from the super ontology and just add the new version again? Will a call of remove() actually remove the whole sub-ontology from the main super ontology or just that root node of the sub-ontology?
 
thanks,
BO

The latter, OntResource#remove just removes all RDF statements that 
refer to that resource, it does not traverse the OWL graph.

Indeed ontologies need not be trees so the notion of a root sub-ontology 
may not be straight forward.
