Re: comments on http://www.w3.org/TR/2002/WD-rdf-sI mean
"Person", as a member of "Class", denotes the name of a group
and
"Person", as a subclass of "Resource", denotes people.

You could say that this is my "taxonomy" bias again.
I see people as part of "Resource", not as part of "Class".

    Note the difference between Person/Class and Person/Resource.
    1. Dick is a member of Person & Person is a member of Class & Dick is unrelated to Class
    2. Dick is a member of Person & Person is a subclass of Resource & Dick is a member of Resource


  True. Every member of Class is a subclass of Resource, and everything is a member of Resource.


    Class and Resource are two classes with very different natures. 


  No, they are both classes in exactly the same sense, but they have different kinds of member. More exactly, Resource contains all the Classes but also some other stuff.


    I'd say the "meaning" of Person with respect to Class is very different from the "meaning" of Person with respect to Resource.


  I have no idea what you mean by 'meaning with respect to'. Can you elucidate?

      Given the normal definitions of person and Dick McCullough and ignoring the
      "'s I would expect to model these as:

         Person rdfs:type rdfs:Class .  # Person is a member of rdfs:Class
         Dick   rdfs:type rdfs:Person . # Dick is a member of Person

      i.e. the latter of the two options you offered.

      Brian
