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.

Aaron, I completely agree that the WCS core should be N-dimensional.The misconception is that core is a profile implemented on its own, there fore it should be the minimal, i.e., 2-D set.Core is the core concepts that are the made specific through extensions. So core should be N-dimensional (as in AS Topic 6) and there should be an extension for that together defines a 2-D profile.George
