Hi! I try to figure out wether a settheoretical interpretation of the RDF-schema is possible or not. I refer to both schema specifications from 3. March 1999 and from 27. March 2000 as well. They show rdfs:Class to be subClassOf rdfs:Resource and an instance (type) of itself. This raises the question if then rdfs:Resource is also an instance of itself for the property of being instance of oneself is a property of a class and such properties are inherited along the subClassOf-relation. If there was just one class that's an instance of itself this would be no surprise. All objectoriented programminglanguages have to define such a class. But it would be useless and confusing if the RDF-schema specifies at least two classes to be instances of themselves. At the moment I think that the RDF-schema enforces the equalization of instances and classes for any subClassOf rdfs:Resource inherits the propery of being instance of itself. Am I doing wrong?
