Only awww:InformationResources can have awww:Representations (i.e., can return 200 OK), and a dog is not an awww:InformationResource, so it cannot return a awww:Representation.

OK, I'm not going to be a pedant and say that resources don't respond
with HTTP response codes, servers do. 

I think you missed my point though. I can configure my server to return
200 OK for any URI it controls so your original statement doesn't help
me (in the guise of an everyday web site operator, not a semweb hacker)
decide whether that conflicts with webarch.

To follow on from your dog example, the missing information I need is
the assertion that:

ex:Dog owl:disjointWith awww:InformationResource .

it's intuitive that if ex:Dog is the class of real-world dogs then the
above is true, but it's less clear that

ex:RdfGraph owl:disjointWith awww:InformationResource .

or

ex:XmlNamespace owl:disjointWith awww:InformationResource .


And the everyday website operator needs to know those kinds of things to
configure their web server. How do we help them?
