In my previous post, this doesn't seem quite right either:

The goal is to optimize (minimize) size, while still denoting the 
resource. Say the URI is http://example/people/JohnBlack. What is the 
smallest graph that denotes me. If the graph just includes my weight 
of 190 pounds, it describes me and it may be minimal but it doesn't 
denote me. If it includes my entire autobiography it denotes me but 
it is not minimal. 

Just to say a graph is an "optimal body of information" seems to leave 
out the primary objective of denoting.
