nice idea.

I note the following in http://www.w3.org/2004/02/skos/core/history/2005-03-31 :

1. <rdf:RDF xml:base="http://www.w3.org/2004/02/skos/core">
2.   <rdf:Description rdf:about="">
3.     <dc:title xml:lang="en">SKOS Core Vocabulary</dc:title>
4.     <dc:description xml:lang="en">
5.      An RDF vocabulary for encoding simple concept schemes such as thesauri and subject heading lists.

15.</rdf:Description>

Line 1 is fine, as it allows convenient relative URIs in the rest of
the document.  However line 2 is suspect as, for example, the
date modified should apply (only?) to this historical version.
I suspect that lines 7-9 probably also should be properties of
a particular historical version rather than the canonical namespace.
