I should have mentioned that I was aware of that.  It's much 
more a vocabulary for encoding whole HTTP messages, than for 
metadata about the resource in the message body.  So for 
example, if <http://example.com/foo.jpg> is served with:

   Content-Length: 514090

this translates to RDF as:

   @prefix http: <http://www.w3.org/2011/http#> .
   [ a http:Connection ;
     http:connectionAuthority "example.com" ;
     http:requests (
       [ a http:Request ;
         http:absolutePath "/foo.jpg" ;
         http:headers (
           [ a http:RequestHeader ;
             http:hdrName
               <http://www.w3.org/2011/http-headers#content-length> ;
             http:fieldValue "514090" ] ) ] ) ] .

I dare say that has uses, but it's a long hugely 
over-complicated for what I want.

I wondered whether it might be possible to extract from that 
the following:

   @prefix hdr: <http://www.w3.org/2011/http-headers#> .
   <http://example.com/foo.jpg> hdr:content-length 514090 .

But it isn't, as hdr:content-length is declared an 
http:HeaderName which is an rdfs:Class, not a subtype of 
rdf:Property.
