I guess you mean "information resources" here; all things are resources, 
still (in RDF/OWL speak)?

Erm, eh, huh, etc? do you mean "possibly be an HTTP endpoint of the 
non-information-resource type"? Or I'm as confused as you are :)

you seem to be using "endpoint" in two ways here. Initially as something 
like "http name", ie. used for all things that are named with "http://". 
Then at the end you talk about http-namable things that can't be 
endpoints. This is the usage I prefer btw; since endpoint sounds like a 
bit of technical network-engineer plumbing.

Aside: what do we make of data: URIs? On the TAG webarch definition, 
they seem canonical examples of information resources; but they lack 
many of the other characteristics of HTTP-based information resources, 
ie. they are endpoint-free, don't have conneg, etc.

cheers,

Dan
