ACTION: Ralph followup with Dublin Core on what's going on with their namespace URI [recorded in http://www.w3.org/2007/12/06-rdfa-minutes.html#action01]

Context:
During a discussion of "follow your nose" principles [1] we got
to talking about the examples we use in the Primer and noted
a desire that the examples also be illustrative of best practice
w.r.t. the SWD "Recipes" Working Draft [4].

Ben and I were both remembering that at one time there
was an HTML version of the Dublin Core namespace document.
We both were surprised that there was no longer an HTML
document served at the Dublin Core namespace URI and
I took an action to find out why our memory didn't match
current reality.

Resolution:
It turns out that Ben and I were remembering a *very* old state
of reality.   The Dublin Core 1.1 vocabulary has been served
in RDF/XML form since 2001 [2].  Until August of 2006 the
content type had been given as text/html.  In August 2006
the content type was changed to application/rdf+xml, per
W3C recommendation.

So, it seems that Ben and I were having flashbacks to pre-
DC 1.1 days when we thought we'd seen HTML served from
the namespace URI.  That hasn't actually been the case for
many years.

I think this completes the action I had from that discussion.

I have it on good authority (see [2,3]) that there are plans in
place to fully support redirects of the form recommended by [4].
So we may continue to use the Dublin Core vocabulary in our
examples and expect that at some point in the future it will
serve multiple content types as preferred by a client.
