MW: There is a ZIP file you can download with an HTML version of
the model. Have you tried that?
MW: I am currently working with others on an update to that model
which should both simplify and enhance its capability.

MW: Yes. Another one to try to find is the SC4 Data Architecture Preliminary
Work Item page, where you should be able to find links to "Some notes on the
nature of things" and the EXIST language, amongst other things.

MW: Class, a set to which we attach some significance.
MW: Union, the usual set theory definition. The set whose members are a
member of one set, and or the other that you are making the union of.
MW: Intersection, the set whose members are members of both sets that are
being intersected.

MW: a set/class whose membership can be defined in terms of other sets and
perhaps particular objects. An easy example is a class that is defined in
terms of the intersection of two other classes, e.g. red cars.
