I think asking "whether an X is an information resource" is the wrong
question.  I don't think it is a matter of discovering a naturally
occurring entity and then deciding whether that thing *is* an
"information resource".  An "information resource" is role within the
web architecture (and semantic web architecture).  

I think a more appropriate question would be to ask "whether X *should*
play the role of an 'information resource'" (and hence return
"representations" in 200 responses).  The standard TAG guidance is to
mint different URIs for different things:
http://www.w3.org/TR/webarch/#URI-collision
and this (I believe) is the basis for suggesting that a person or a dog
should not play the role of an "information resource": one is likely to
wish to separately refer to the dog as distinct from the web page about
the dog.

However, there is no clear, hard and fast distinction between (naturally
occurring) things that *should* play the role of "information resource"
and those that should not.  Whether X should play this role depends on
what you want to accomplish.  For one application, it might be best to
view X as an "information resource" (and hence configure a web server to
return 200 responses with "representations"), whereas for another it may
be best to view X as distinct from the "information resource" that
provides representations describing X.

The overriding point is that, whether or not something is a "information
resource" is a *choice*: it isn't a matter of putting the Hogwarts
sorting hat on X to find out whether X *is* an information resource by
nature.  It's a matter of *deciding* whether to view X as an information
resource when one mints a URI for X.  And by the httpRange-14 rule, if
you configure your server to give 200 responses, you have indicated that
you have chosen to view X as an "information resource" (in addition to
whatever else it might be).
