[ STC in VOResource records]

[Mireille Louys]

Hi , all,

I have read the various comments and suggestions concerning the ID/IDREF 
mecanism in STC
and I just want to expose my view , as a data modeler from the 
Characterisation DM effort.
The Characterisation XML schema is also based on STC  and factorises the 
Coordinate systems at the top level elements of the Characterisation 
tree, using the STC/lib definitions.
Lower elements just refer to the proper Coordinate systems using the 
IdRef mecanism.

Such a factorisation was helpful in our case:  it relies on a unique 
definition of the Coordsys names, defined in STC lib and pushes for less 
redundancy in XML documents.

If you go for solution #1, and define a specific ID building procedure, 
  please mention it on the DM list too.

Cheers and seasons greetings, Mireille
