That tripped up POWDER too. We want to be able to associate a free-text
tag with a semantically-defined meaning. Kjetil Kjernsmo engaged with
the SKOS folk on this back in June [1] last year with the aim of linking
tags in my.opera.com to our concept of a set of descriptors that can be
applied to multiple resources. We ended up defining our own vocabulary
term mapsTo [2]. The whole POWDER structure is undergoing an overhaul
right now so I wouldn't put a lot of store in this until our next drafts
are published but the basic need to associate SW and tagging remains.
I remember Chaals M-N once saying something like you should almost never
restrict the range and range of a vocabulary term unless you absolutely
have to because you can bet you'll want to use it in a different
situation about 10 minutes after the vocabulary is published in its
final form. The constraints on SKOS seem to bear this out.
Phil.
