The doc appears to be silent on how the status code themselves should
be represented. If they're just a string literal then there's not a
lot can be said about them. So given that this is a known set of
important things which have a couple of attributes, I'd suggest
creating a class for them:

:StatusCode a rdfs:Class .

giving the individual codes URIs, e.g.

<http://www.w3.org/2006/12/http#200>

with the current schema extended a little:

<rdf:Property rdf:about="&http-ns;responseCode">
  <rdfs:label xml:lang="en">Response code</rdfs:label>
  <rdfs:comment xml:lang="en">An HTTP response code</rdfs:comment>
  <rdfs:domain rdf:resource="&http-ns;Response"/>
  <rdfs:range rdf:resource="&http-ns;StatusCode"/>
</rdf:Property>

individual codes could be described something like this:

<http://www.w3.org/2006/12/http#200>
   a :StatusCode ;
   rdf:value "200" ;
   rdfs:label "200 OK" ;
   dc:description "The HTTP 200 OK response code "
   rdfs:isDefinedBy
<http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.1> .

There may be other constraints available (making the list a
collection? using OWL property restriction on responseCode?) but I
think just giving the things URIs would be useful in itself.

Cheers,
Danny.
