Rick,

Two things I spotted:

A)

In your version "IAU/IVOA Thesaurus - Version Fri Oct 5 15:27:30 2007", which has the xml:base line added, I think you want to keep the "#" character before all the resource names - so that you have

   <skos:hasTopConcept rdf:resource="#53_Persei_stars"/>    <skos:hasTopConcept rdf:resource="#aberration"/>

   <skos:Concept rdf:about="#53_Persei_stars">

etc. This is so that you refer to

http://www.Astro.physik.Uni-Goettingen.DE/~hessman/rdf/IAU#53_Persei_stars

(or IAU:53_Persei_stars).

At present, the file refers to

http://www.Astro.physik.Uni-Goettingen.DE/~hessman/rdf/53_Persei_stars

etc (or at least that's what cwm [1] and triplr [2] tell me it says)

I've got a quick-hack version at

   http://hea-www.harvard.edu/~dburke/playground/iau-djb.rdf

and you can see the N3 versions - generated by cwm - at

   http://hea-www.harvard.edu/~dburke/playground/iau-orig.n3    http://hea-www.harvard.edu/~dburke/playground/iau-djb.n3

[1] http://www.w3.org/2000/10/swap/doc/cwm.html [2] http://triplr.org/

Of course, this assumes we want all terms to be fragments within a single resource.

B)

A couple of terms have spaces in them which should probably be converted to "_" - for instance

   <skos:hasTopConcept rdf:resource="air conditioning"/>    <skos:Concept rdf:about="air conditioning">

   <skos:narrower rdf:resource="cosmic rays"/>    <skos:related rdf:resource="cosmic ray_showers"/>

HTH,
Doug
