semantic web - protege how to add a reference to another ontologya -
i tying integrate ontology ontologies. did importing ontologies in protege, works, protege lists classes, normally. looking if there way in reference (uri) of these ontologies , can use them prefix.
ofc, building ontology using owl2
i hope me
if want reason , materialise facts based on terms relating referenced concept, need import ontology referenced concept belongs.
e.g given external ontology following statements:
ex:person owl:class; rdfs:subclassof ex:agent.
if reference in without importing:
ex2:doctor owl:class; rdfs:subclassof ex:person.
and make following statement:
ex2:jack ex2:doctor.
an run through reasoner, materialise following:
ex2:jack ex:person.
but not following:
ex2:jack ex:agent.
to materialise latter, need import ontology statements ex:person.
