"Benjamin Nowack" <bnowack@appmosphere.com>>- what about subclassing Polygon and Ellipse, so that > w3p:Circle rdfs:subClassOf w3p:Ellipse and > w3p:Rectangle rdfs:subClassOf w3p:Polygon. > This would lead to only two basic shapes/region types that > a tool would need to support. (plus the optional boundingBox) This isn't possible since the coords property changes its semantics depending on the rdf:Type of the class, if we subClass like the above, we end up in the situation that with <some img:Rectangle> img:coords "20,20 40,40" then doing the sub/superclassing <some img:Polygon> img:Coords "20,20 40,40" Which is not equivalent!
