Hi Murray,

Sometimes I'm a pompous ass.  I think I was this time.

> >http://www.stephenking.com/pages/works/stand/ "is a" "web page"

That was the essence of my comment.  That URI identifies a web page
about the novel, not the novel itself.  And Ian's reply suggests a
simpler fix to the example than had previously occurred to me.

So if I had written instead something like:

There is a buglet in the RDF because
http://www.stephenking.com/pages/works/stand/ doesn't identify the
novel.  This can be fixed by just dropping the URI giving instead ...

  <dc:title>The Stand</dc:title>
  <dc:creator>Stephen King</dc:creator>
        rdf:resource="http://en.wikipedia.org/wiki/Stephen_King" />

This says "there is something called 'The Stand' which was made by
Steven King".  It doesn't give a URI for the 'The Stand' because we
don't have one easily to hand.  

Dan may disagree with the claim that 


Does not identify the novel.  I think there are murky complex waters
there which the TAG pondered on for a long time and since we'd like to
get done quickly we'd be best to stay away from and stick to examples
that don't stray into the tarpit.  There is nothing here that affects
GRDDL itself - its just an example.
