Good points.

Based on the comments on HTTP URIs at
https://github.com/OSGeo/Cat-Interop/issues/3, the OGC has this at
www.opengis.net.  However the structure is not SKOS-like. I guess one
factor is how deep version negotiation would go.

Then again, we could implement this in OSGeo and have resolver back to
their authoritative resources (i.e.
http://osgeo.org/vocab/service/csw/2.0.2 could resolve to
http://www.opengis.net/cat/csw/2.0.2.  Does this sound useful/make
sense?
