3D data model: plan

[Igor Chilingarian]

Hello Doug,

Today I discussed with Francois some questions concerning 3D data model

Your idea about science case driven approach is a perfect proposition.

I have a kind of plan for what to do for a moment:
  1) Define clearly the science case for IFU data I'm working on: studies of
      stellar populations in nearby galaxies using absorption-line spectra
  2) During the next week hopefully we'll have two science cases formulated
      for Fabry-Perot data: studies of the gaseous kinematics in disc
      galaxies, and studies of gaseous shells (SN remnants) in nearby
      galaxies. I asked scientits working with this type of data to describe
      these cases.

 Each of these science cases will be presented as a short part of text (15-20
lines) including scientific objectives and brief description of the scientific
data processing with the requiremets about the descripition of the data.
It should help to figure out the requirements for the 3D data model, and
for 3D data access layer. We'll probably need the same to be done for
other 3D data types, but I don't know personally people working with radio
and X-ray cubes.

  3) As Francois proposes me, I'll try to add the necessary features to the
      Characterisation data model to be able to deal with the IFU data.
      I'll do my best to finish this (with a help of Francois) before the
      end of March
  4) At this point it will be clear (hopefully) what we need to have in the
      3D data model, and whether we need it separated from more general DMs
      (Characterization and Observation), and it would be possible to start
      the real work on the document draft.

Do you agree on such a plan?

With best regards,
						Igor
