Two-Way Semantic Referencing Any kind of resource can be an instance in more than one ontology Any kind of resource can be an instance in more than one ontology –The technical ontology tells TELOS how to execute the resource –A domain ontology tells a search engine what knowledge and competency is owned by the ressource
