[Voevent-core] Fwd: standard vocabulary

[derriere at newb6.u-strasbg.fr]

Quoting roy at cacr.caltech.edu:

>>  In which case GRB is not really relevant as a UCD, nor is
>> process.variation.burst;em.X-ray.

   Very good point, Roy! It could not be said more clearly.

>> So unless UCDs are now going to be turned into the new astro thesaurus or
>> a type of astro ontology, it doesn't seem to make sense to have a UCD for
>> GRBs.

> Thesaurus and Ontology imply a set of nodes and relations between them. At

> We could in the future build more structure.

   This is something that will be discussed in the second UCD/semantics session
today. I have a talk about ontologies and I address precisely this issue. I
know Tony will be in the other room for Registry, but we can discuss this
during coffee break.
