VEP-004: #counterpart in datalink/core

[Mireille LOUYS]

Hi Markus , Hi all,

I think this term fits the use-case when we want to relate to another 
science data item that brings material
for interpretation outside the scope of an existing project.
The use-case is /comparing/ science data from other experiments to the 
content of #this.

In the description text below, I agree with the first part  .
What is the meaning of the last part?

'spectra of dust of common origin but different laboratories'

are good examples of dataproducts of different provenance.

Can we put it in the example section ?

Something I am not comfortable with in the VEP process is the fact that 
we discuss one term , separated from the others and therefore do not 
always see the coverage, depencies  and overlap between the notions .

currently we have : 
http://www.ivoa.net/rdf/datalink/core/2020-06-26/datalink.html

as far as I understand it :
#conterpart is a main term serving comparison purpose
orthogonal in meaning to
#progenitor
#calibration
#auxiliary
#preview
and there child terms


Used_in section:
I suppose there are also use-cases catalogs enriched with associated data.
I let archive scientists and providers expand on this more precisely.

cheers , Mireille.
