Yes. Alternatively, it's accepting that the horse has already left the
barn. There are all sorts of bare http: URI out there that various
persons and systems use to identify things that aren't "information

If we were starting over, maybe we could establish conventions that
allowed us to distinguish between these two classes of resources. And
because there would be no legacy and no firmly held convictions on the
other side, maybe the world would go along.

But that ain't the way it is.

I think that's the wrong analogy. The problem we have here is that we
can't agree on what, if any, error there is.

I tried to formulate a compromise more than a year ago[1]. I got both
barrels from Roy and it went down in flames. Maybe your compromise is
better :-)

Explain again how this redirection helps.

  An attempt to GET http://xmlns.com/wordnet/2.0/Hoary_Marmot
  returns 302 (303? 307?) http://xmlns.com/wordnet/2.0/Hoary_Marmot/about.rdf

So your SW application loads about.rdf and asserts that it is a document
but it makes no assertions about Hoary_Marmot because it wasn't able
to "GET" a representation for that resource?

Does the fact that you got 30x imply something about the Hoary_Marmot?
Why not?

If about.rdf includes <rdf:Description about=""> do the enclosed
properties refer to Hoary_Marmot or about.rdf?

                                        Be seeing you,
