That is what I was calling isomorphism (which I still don't think was
inaccurate). But ok, say there are correspondences instead. I would
suggest that those correspondences are enough to allow the description
to take the place of a representation under HTTP definitions.

I'm saying conceptually it doesn't matter if you can put it over the
wire or not.

Difference sure, but not necessarily relevant.

It would save a lot of effort sometimes (walkies!) but all I'm
suggesting is that if, hypothetically, you could teleport matter over
the internet, all you'd be looking at as far as http-range-14 is
concerned is another media type. Working back from there, and given
correspondences as above, a descriptive document can be a valid
representation of the identified resource even if it happens to be an
actual thing, given that there isn't necessary any "one true"
representation. We don't need the Information Resource distinction
here (useful elsewhere maybe).

Cheers,
Danny.
