Discussion on concept UCD: meta.ref.pid/ Persistend IDs and their various flavours

[Mireille LOUYS]

Hello Yan , hello Semantics members,

Thanks for bringing this use-case .

I understand you need a ucd to tag your ePIC pid column .
In terms of content descriptor , I understand you manipulate a meta.id .
but it's a persistent one , defined by ePIC .
So a general UCD for this could be
P     meta.pid     a general persistent identifier

Vizier also uses PIDs , but resolved following the doi standard. The UCD 
here is the existing /meta.ref.doi/
which implies this ref can be resolved according to this standard .

The same would apply to ORCID , and we could define a new ucd :
P    meta.ref.orcid      An pid resolved by ORCID compliant tools

It is definitely interesting to know more  about your data release and 
what you do with these PIDs in terms of
definition , attribution, resolver, maintenance .

Cheers, Mireille
