[Voevent-core] Fwd: standard vocabulary

[Frederic V. "Rick" Hessman]

I, for one, knew that the AOI was working on a controlled vocabulary,  
but their agenda was always geared towards describing press-images  
rather than defining a general-purpose UCD-like proto-ontology.     
However, their approach is at least systematic, which isn't always  
true for what we've been discussing: both UCD's and the proposed  
standard vocabulary/VOConcepts tend to look like random collection of  
ideas which someday may be organized into an ontology.  Yes, I know:  
it's easy for AOI to be systematic when they limit their scope from  
the beginning (e.g. they don't have words for things which aren't  
easily shown in press-images).

The bottom line is that, yes, it would make sense to bring all of the  
vocabulary people together and to see if we can agree on a common  
basis.  My guess is that there's little chance, so Rob's idea of  
everyone having their own private vocabularies (e.g. VOEvent's "GRB"  
versus the UCD-like "process.burst;em.gamma" versus nothing yet for  
the AOI list) and the IVOA providing the standard vocabulary as the  
means of constructing conversion tables still sounds like the best  
path: everyone gets what they want and the IVOA gets a common  
standard which everyone can live with.   For example, adding standard  
vocabulary to the AOI list as a further column would be trivia and  
any missing elements would be a good sign of where the proposed  
standard vocabulary needs some additions.
