Format of tokens

[Alasdair Gray]

Hi Rick,

 

I think there might be a slight problem with your script that generates the vocabularies. If you look at any relationship, you will find that it points to itself rather than another concept.

 

I have done a quick analysis of the IAU93 and IVOAT vocabularies.

 

Number of

IAU93

IVOAT

Top level concepts

1720

1203

Concepts

2947

2892

Broader relationships

1716

2307

Narrower relationships

1716

2307

Associative relationships

7647

8040

 

Cheers,

 

Alasdair

The original IAU thesaurus in SKOS format in a semi-final form along with the latest IVOAT and experimental math thesauri are available at the cleaned up site

Others are forthcoming.   As each thesaurus is nominally OK'd by the semantics group (e.g. IAU93), they need to be moved to the IVOA.

 

Have we agreed on the TokenSyntaxMostLikelyToBeLeastDispleasingToTheLargestNumberOfSemanticsWorkingGroupMembers?  If so, I believe the IAU93 thesaurus can be declared practically done.   Check off item, move to next....

I might add that therefore limiting the effort to SKOSifying the IAU Thesaurus will bring the most rapid IAU recognition possible.  In the mean time, there's no reason we can't use intermediate work products within the IVOA.  - Rob

 

Indeed there's no reason why we can't have several thesauri up and running when we present the SKOS proposal to the IVOA and IAU.  I believe that Rob is practically finished with the VOEvent thesaurus.....   If IVOAT is preliminarily finished, then hopefully people will simply nod at the fact that IAU93 is formally expressed for compability and political purposes but not bother to use it (heaven forbid).
