I'm getting a bit worried about the A-box/T-box discussions.
We have "classes as instances" on our requirements list.
We use it a lot in our (RDFS-based) applications, for example:

  rosch:natural-category rfs:type rdfs:Class
  aat:seating-furniture rdf:type rdfsClass

  aat:chair rdf:type rosch:natural-category
  aat:chair rdfs:SubClassOf aar:seating-furniture

In words: a "chair" is a subclass of "seating furniture" (in the Art and
Architecture Thesaurus) and an instance of a Roschian "natural category"
(important meta-info for index/search purposes). 

Does this still mean something using dark triples?
