  sub:paragraph c4o:hasContent "When developing a new ontology it is recommended to reuse existing ontologies as much as possible. In this way, one can focus on defining the specific knowledge of the application. The reuse of external ontologies, not only saves time but also gives the advantage of using mature and proved ontological resources that have been validated by their applications and (some) by the W3C." ;
