The big problem with the IAU-93 is that there are no definitions for the 
terms. This is another reason we need to get the IVOAT, or at least an 
early version of it, ready for use. However, there will ultimately be 
the need for mappings between pairs of vocabularies as it may not always 
be possible to express these by going through a central vocabulary.

As a point of interest, I am just about finished developing an 
application to aid the generation of mappings between a pair of 
vocabularies. Once I have ironed out a few glitches and got it 
conforming to the latest skos reference working draft I will issue it 
for use.
