[obs-tap] draft summary: topic 1 *Data product type*

[Francois Bonnarel]

HI Mireille, all,

     Without the introduction of a new otional subproduct type I am 
afraid that the procedure
you are proposing will end by a long flat heterogeneous list.  This  
optional subtype will  have
 the benefit to put some structuration in the whole product-type affair.

     By the way I have a question about StandardREgExt you are 
mentioning  for ObstTAP. Will it describe all the Obscore fields
or only give a link to the TAP schema  ?
Regards
François
