Re: The notion of a "classification criterion" as a class

Bene,

When your requirements are stated in the abstract, it's hard
to see what you're asking for.  Furthermore, you're combining
issues about the problem you're trying to address with partial
solutions stated in terms of various tools (OWL, facets, etc.).

I think it would be clearer if you described a typical example
that motivated this discussion.  To avoid prejudging any kind
of solution, I suggest the following:

  1. State the example in ordinary English as a domain expert
     would describe it.

  2. Discuss the issues about mapping that problem to OWL DL,
     facets, or other notations you consider relevant.

  3. Explain the difficulties or limitations in those notations
     that you are trying to address by whatever extensions you
     are asking for.
