Hello, The 11th rule in the RDF Model Theory which states that if xxx rdfs:subClassOf yyy and aaa rdf:type xxx . then aaa rdf:type yyy does this rule applies if xxx is subclass of rdfs:Class? More precisely, if the following facts are stated: the class MyClass is subClassOf rdfs:Class and C1 is instance of MyClass i.e., <rdfs:Class rdf:ID="MyClass"> <rdfs:subClassOf rdf:resource="http://www.w3.org/2000/01/rdf-schema#Class"/> </rdfs:Class> <MyClass rdf:ID="C1"/> can I infer that C1 is a class? Or it is should be explicitly stated in the RDF file that C1 is instanceof rdfs:Class? Repsectively, if I define a class MyProperty as subclass of rdf:Property and P1 is instance of MyProperty i.e., <rdfs:Class rdf:ID="MyProperty"> <rdfs:subClassOf rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Property"/> </rdfs:Class> <MyProperty rdf:ID="P1"/> can I infer that P1 is a property?
