Classes in RDF and SMW
An RDF class is defined as the set of its instances. Consider the class of abstract ideas. Members – instances – of that set include love, honour, duty, pi, evolution, etc. This view of a class is a mathematical concept, so the set of abstract ideas is both an idea and quite abstract, so therefore is itself an instance, or member, of the class abstract ideas. More prosaically, if a class is a set of things, then RDFS classes both denote sets of things, and are themselves instances of the set of all classes, aka rdfs:Class.
In SMW a class is page It is a thing.
