Simon,NcML (i.e. the netCDF Mark-up Language) is already able to formalize and encode multidimensional gridded-based datasets. We developed the ncML-GML in order to mediate ncML and GML and map these more general structures into a set of "simple" coverages, according to ISO 19123 model.

Ron - I agree with you on Coverages, conceptually. There can be noargument with this. I spent some time the week before last with a team who are interested inthe variation of Gibbs free energy of a chemical species as a functionof 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.
