ok........ thanksfor your reply lan... i will read the content. but i need to create the relation between two ontologies. consider ont1 and ont2 are the two ontologies. if both ont1 and ont2 have a class named employee. And employee class in ont1 have a subclass named john. but ont2's employee class doesn't have that class. i need to specify a relation that john "is-a" subclass of ont2's employee class. how to do that using jena? is it possible?
