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.
