I'm wondering how that works in the higher level products...
I've added TimeSeries and Spectral to your hierarchy chart.
   * Having given this no thought.. If these are isolated models, I'd
expect that Spectral and TimeSeries could not be expressed as a simple
extension of Cube (as the current prototype model is).

If I'm a provider of Spectra, Photometry filters, TimeSeries, etc..
  1) How do I know that I should provide annotations for the 'data' as
Measurements and Coordinates?
  2) From that perspective wouldn't I expect that annotating as a
TimeSeries should be all I need to do?
      o If I neglect/fail to provide them, it is a valid TimeSeries, but
one with no Measurements.
