Ron - I agree with you on Coverages, conceptually. There can be no argument
with this.
I spent some time the week before last with a team who are interested in the
variation of Gibbs free energy of a chemical species as a function of
temperature and pressure.
This is conventionally represented as a grid or map of values in P-T space,
which is structurally identical to a gridded coverage.
My point is that generalizing in this way has significant implications to our
claims that GML is an implementation of ISO 19123. 19123 is specifically
limited to spatio-temporal domains, conventionally defined.
My point really is that we need to consider whether we really want the struggle of making "coverage" the
generalized class, or perhaps invent "functor" or "map" or "function" for this purpose,
and leave coverage alone, as originally defined.
