WD-DataLink-1.0

[Louys Mireille]

Hi Arnold , Hi all ,

The goal here is not to classify things again in a general data model 
and force a categorisation of data products, but on the contrary ,
to record some terms that will be meaningful. Applications could follow 
the links between datasets and touch the attached data / metadata useful 
for their context/ usage.

if the radio community uses "Beam" instead of PSF, the usual "beam" term 
would be meaningful and understandable for the context of
radio oriented applications.
the idea was to relax the constraints we had in the data modeling and 
offer more flexibility.

Best wishes,
Mireille
