and from you're other reply:

that's self definitional, the resource /is/ the information, and the 
current state that resource comprises /fully/ of the information you get 
in the resource representation, it is realization (copy/instance) of all 
the information provided at some point in the past - it may not be a 
full set of information about the thing(s) described in the information, 
but it is the full set of information made available by that resource. 
The information provided is the resource state.
