I am just considering: Wouldn't it be better to use for those "frozen"
ontology versions an URI scheme like in


with the "V1" /before/ the "refdata" part. Or with the publishing data
contained as in:


like it is used for the RDF and OWL namespaces. 

My concern with your proposed ".../refdata/V1" scheme is that I would regard
this more to be an URI for an OWL class named "V1" within the "OASIS"
ontology (if slash-URIs are used). So, this might (while very unlikely to
happen) collide with such a class name in the ontology. And, perhaps,
ontology tools might get confused by it? I don't know, just have a somewhat
bad feeling.

On the other hand, the Dubling Core also uses the version number at the end,
and so does FOAF:


So, perhaps still not a problem?

This might be somewhat pedantic, I suppose. :-) But I would like to use the
opportunity of this thread to discuss some "best solution" for such a
certainly pretty common scenario. Or is there already some "best practice"
document out covering this topic?
