===Relation to RDFS===
OWL Full is intended to be compatible with [[RDF Schema]] (RDFS), and to be capable of augmenting the meanings of existing [[Resource Description Framework]] (RDF) vocabulary.<ref>{{cite web |url=http://www.w3.org/TR/2004/REC-owl-features-20040210/ |title=OWL Web Ontology Language Overview |first1=Deborah |last1=McGuinness |author-link=Deborah McGuiness |first2=Frank |last2=van Harmelen |author-link2=Frank van Harmelen |date=2004-02-10 |work=W3C Recommendation for OWL, the Web Ontology Language |publisher=World Wide Web Consortium |access-date=18 April 2010}}</ref> A [[model theory]] describes the formal semantics for

So, the meaning of OWL Full ontologies are defined by extension of the RDFS meaning, and OWL Full is a [[extension (model theory)|semantic extension]] of RDF.<ref>{{cite web |url=http://www.w3.org/TR/owl-semantics/rdfs.html |title=OWL Web Ontology Language Semantics and Abstract Syntax Section 5.
