In RDF an edge corresponds not to the property or predicate URI but rather to the triple itself. Many edges may share the same predicate, so the predicate URI does not 'point' to or identify the edge itself. > > What I've got at the moment is something like this : > > Identifiable (Temporal, Described) > | > Item > / | \ > Vertex Edge (Adjunct) > > Identifiable more or less corresponds to URI This is the problem, an "edge" is not a URI as opposed to vertices which are named by URIs.
