I also think it might be interesting to push this concept further and describe higher level constructs with the RDF. I'm very interested in showing some relationship between ETag and Content-MD5 as identifiers. There is also a (maybe weak) relationship between Content-MD5 and Content-Length in that both can be used to verify a piece of content. The below RDF is definately on the right track. One bit of feedback that I have is that while specifying type is very useful, it should also be possible to convert the RDF back into HTTP headers without too much trouble. While I don't have time right now to really dive into this stuff, I'm very interested in hearing others thoughts on the topic. Hopefully in the next couple of months I'll have some time to really play around with this. -Justin > > <> http_request:uri [ # a rdf:Bag ; > :value > "http://www.example.com/pages/dyn/1.html?username=bob@session=132323 > " ; > :scheme "http" ; > :host "www.example.com" ; > :port "80" ; > :path [ # a rdf:Seq ; > :value "/pages/dyn/1.html" ; > rdf:_1 "pages" ; > rdf:_2 "dyn" ; > rdf:_3 "1.html" ; > ] ; > :query [ # a rdf:Bag ; > :value "username=bob&session=132323" ; > :username "bob" ; > :session "132323" ; > ] ; > ] . > <> http_request:method "GET" . > <> http_request:pragma [ # a rdf:Bag ; > :no-cache "null" ; > ] . > <> http_request:user_agent "Mozilla/1.0 (blah, blah)" . > <> http_request:cookie [ # a rdf:Bag ; > :sessionID "2323113132" ; > :name "bob" ; > ] . > <> http_request:authorization [ # a rdf:Bag ; > :scheme "basic" ; > :userid "bob" ; > :password "bobspassword" ; > ] . > <> http_response:status "200" . > <> http_response:cache_control [ # a rdf:Bag ; > :max-age "600" ; > :no-transform "1" ; > ] . > <> http_response:set_cookie [ # a rdf:Bag ; > :sessionID [ # a rdf:Bag ; > :value "132134" ; > :expires "1002828066" ; > :path "/" ; > :domain "example.com" ; > :secure "0" ; > ] ; > :name [ # a rdf:Bag ; > :value "bob" ; > ] ; > ] . > > -- Justin Chapweske, Onion Networks http://onionnetworks.com/
