Thank you andy...i really appreciate ur concern...Actually, i was looking for something specific to ontology...where we create a main node..and sub-nodes within..so, if i have USERS as the main node, then i'll have types of users as the subnodes.To those types of users, i want to assign specific rights through my ontology framework itself(using OWL)..
could u throw some more light into the matter?
Thank You
