The only person trying to do this was David. Tim has clearly said that
the wa-representations do not in themselves determine the resource.
I'm trying to draw
a clear distinction by introducing the notion of a generic resource's "trace".
The trace isn't the GR, any more than the graph of measurements of
a room's humidity is the room's humidity.

This seems like a good thing to model. But there has been general (and
hard-won) agreement in this group that an HTTP entity is a
wa-representation. You'd have to invent a new class whose individuals
possess a binding for the base URI. We could call it an
hh-representation...  (What is Moby Dick's base URI, though?)
