dimension data model/context

[znichollscr]

Is validation-key meant to be the value or are we missing a key that holds the actual dimension, separate from id (a unique, lowercase id), validation-key (not clear if this is the value) and ui-label (a human-readable version for display, not the actual value).

Are we duplicating CF by including axis-flag?

What is spatial shape? Is that a key we want to keep or would it be simpler to just drop this (so we don't have to manage this field which doesn't seem to have a strong definition anywhere from what I can tell)?
