Joshua, everyone,

I've just edited the wiki's mapping section to give a more accurate 
reflection of ADMS. Not sure what old version you were looking at but 
the table should be OK now. I've removed completely a section where ADMS 
terms weren't mapped to anything else - I didn't recognise any of those 
as ever having been part of ADMS at all but they must have come from a 
dark corner somewhere that I've long forgotten about. I've also made a 
couple of references to a proposed vocab, RADion, that this schema.org 
extension seems set to make redundant (which is not a bad thing). I've 
added relevant links to the intro paragraph on the wiki. It is designed 
to provide a substrate for vocabularies like this that can then 
subclass/subproperty where necessary. Subclassing schema.org makes just 
as much sense as subclassing RADion.

My only caution about dispensing with RADion altogether and using the 
proposed schema.org extension is that ADMS is already being implemented 
by a number of substantial catalogue owners (incl. OASIS and GS1) but 
it's probably early enough in the cycle to handle this without too much 

Actually, ADMS defines very few terms of its own - it's almost all 
Dublin Core except where it gets into esoteric terms designed to 
describe multiple documents wrapped inside Zip archives that, love it or 
loathe it, is how a lot of organisations publish their stuff. Remember 
that ADMS is not specifically about describing data sets, it's about 
describing vocabularies, code lists and standards. Hence I don't think 
those areas will be of direct relevance here and there's no need to 
clutter up the mailing list with them.
