spectroscopic data model

[Laurent MICHEL]

Gregory,

The situation is that CubeDM and Dataset are stalled by Meas/Coords that 
are both in RFC.
The RFC period is delayed for some pending issues, the most important of 
which is that of reference implementations.

As DM chair, I'm not able commit to a timeline.
The person best qualified to answer this question is likely the editor 
of these models (Mark Cresitello Dittmar <mdittmar at cfa.harvard.edu>).

Do you have a very rough sense of when a proposal based on the Cube and/or Dataset DM efforts could reach the content level of being ready to act as a successor to SpectralDM?  (Not including time to do final polishing, voting, etc.)
