You're right, but IAU93 uses NT's of "chemical element" like
"isotope", "heavy element", etc., so "fundamental chemical element"
was the simplest solution when adding the explicit elements. A
better idea where we can unload the old NT's?

By all means pass them on. If there are any major holes when we try
to pull this off, then people will say "Hey - this is useless: it
doesn't even include XYZ!". Of course, we will ignore the comments
like "... it doesn't even include leftHandedMonkeyWrench or
Suggestions of things to throw out are also welcome.
I recommend "Zen and the Art of Vocabulary Maintenance".
As a bon-bon, I've added a "Sky" vocabulary containing all of the IAU
constellation names, with the genitive and 3-letter abbreviations:
This could be the model for the vocabularies that we could create by
dividing up IVOAT into it's principle components:
- math (see http://www.astro.physik.uni-goettingen.de/~hessman/rdf/
- iau (in the sense of official IAU definitions like constellation
which could make IVOAT more digestible - rather than gorging
ourselves at once, we reduce the semantic problem to several
appetizing courses. The major drawback is having to deal with many
different RDF files in order to do a particular generic astronomical
