Re: [galeon] WCS CF-netCDF profile document

Wenli,

Core is not to be a conformance class on its own.
Clients would need to be compliant to core plus one or more extensions.
Core would specify the equivalent of CV_DomainObject with no detail on the geometric objects.
These would be two conformance classes with corresponding compliance tests: - Core + 2D extension would say CV_DomainObject only contains 2D geometric objects. - Core + 3D extension would say CV_DomainObject contains 3D geometric objects.

Aaron and George,
I think that the main reason to require only 2D in core was to maximize potential implementations. Note that core does not imply the core concept of a (grid) coverage. Core means any sever/client must implement the capability defined as "core capability". Requiring n-D actually does not cause a problem in server implementation because a server can always offer only 2D coverage. However, it is not the case to client implementation. If n-D is required, then a client must be able to talk to a n-D coverage server, even if it needn't n-D data, otherwise it will not be considered compliant.
