But both the abstract trees of Noah's recent imaginings and the mathematical 
abstractions of Pat's original examples are resources that can be infinite - 
or finite but exceeding any "reasonable" limit that you set on their 
representations. So perhaps we should say that any finite or reasonably 
small RDF graph may be an "information resource", but that RDF graphs and 
abstract trees, in general, are not. Sorry, but IMO that sounds broken to 
me.
