REST maps a resource to a set of values over time, each single value has 
a 1:N relationship with representations, "RDF Graph" (the mathematical 
set, platonic abstraction, g-snap) equates to a single value, and "RDF 
Graph Token" equates to a representation of that single value.

In other mails, Sandro's, g-box equates to a RESTful resource, something 
which maps to different values (g-snaps) over time, where g-snap is a 
snapshot of the state of the g-box.

RDF doesn't currently cater for anything like a g-box, and both a value 
and a representation of that value are given the same name "RDF Graph", 
which I believe was Pats original point.

Hopefully Pat will confirm if that understanding is correct.
