RDFS/OWL is *not* an object-oriented model. It is a set theoretic model. A type triple (rdf:type) states that a resource is a member of a set (class). rdfs:subClassOf states that a class is a subset of another.
Properties of classes are not inherited, although properties can be associated with classes by either setting the domain/range of a class (RDFS) or property restrictions on a class (OWL). -- Scott On Apr 13, 9:21 am, [email protected] wrote: > Is this so because the Ontology is not a true-classical OO model? > > Narsim Ganti > > -----Original Message----- > From: [email protected] > > [mailto:[email protected]] On Behalf Of mwz > Sent: Monday, April 13, 2009 10:13 AM > To: TopBraid Composer Users > Subject: [tbc-users] properties assigned to super class > > Hi, Eveyone, > > I found it is interesting that properties assigned to a super class > are not automatically given to its subclasses.
