call for comments for the Characterisation DM PR

[louys at alinda.u-strasbg.fr]

Dear IVOA members,

  At the last Beijing Interop and before, we made public the last 
working draft of the Characterisation Data Model and requested for 
comments.
 From the discussion we had in Beijing, I think that the 
Characterisation Data Model is now ready for the Proposed 
Recommendation process.
This  process begins today and will end on July the 4th, so a little 
more than 4 weeks .

Please review the document at
http://www.ivoa.net/Documents/latest/CharacterisationDM.html
and put your comments on the RFC page at
http://www.ivoa.net/twiki/bin/view/IVOA/CharacterisationDataModelRFC

The Characteristion Data Model provides a standard for describing 
general data sets and is re-used partly in the Spectrum data model.
Implementations of this DM are described in an IVOA Note available at :
http://www.ivoa.net/Documents/latest/ImplementationCharacterisation.html

A list of the Utypes derived from the Characterisation DM is also 
available at :
  http://www.ivoa.net/Documents/latest/UtypeListCharacterisationDM.html

A user's guide for Images in Characterisation DM , helping data 
publishers to map their metadata to the appropriate data model 
concepts, is on line too  at :
http://www.ivoa.net/internal/IVOA/IvoaDataModel/ivoa_char_2d_image_tutorial_1.0.pdf

Please read these documents as well.
They give an overview on the usability of the Data Model concepts and 
help to realise its scope and relevance.

Thanks,

    Mireille Louys
    DM chair
