Re: RDF vocabulary definitions

It was my impression that "instance" was deprecated, to be replaced by "individual".
For example, see http://www.w3.org/TR/2002/WD-owl-features-20020729/ 

However, looking at the OWL document again, I see it uses both terms:
    "Individuals may described as an instance of a Class ..."
This is NOT a good way to describe the relation between Individuals and Classes.
The actual concept-formation process is: Classes are formed by mentally integrating Individuals
(and some Classes are formed by mentally differentiating wider Classes).

re: members & instances -- what's the difference, if any?  

I recommend replacing all "instance" by "member".

Here's a simple definition of "individual" and "class".
An individual is a single concrete existent.
A class is an abstract group (a mental integration) of two or more similar individuals.

  RDF Schema talks about members of classes and instances of classes.  Where 
  did the term individual come from?
