The identification of resources in the Web via URIs [RFC3986] may not be
sufficient to uniquely resolve a document as other factors might come into
play like HTTP content negotiation according to pre-defined user
characteristics. This issue is particularly important for conformance
testing, conformance claims and reporting languages like the Evaluation
and Report Language (EARL, [EARL Schema]) when they address Web resources. This
document describes a representation of HTTP concepts in RDF that will
serve to the purpose mentioned earlier, as it can allow the identification
of resources served via the HTTP protocol. The proposed vocabulary also
includes some extensions to HTTP outside the standard RFCs.
[Note] Shall be mention HTTPS here?

This note presents an RDF representation of the HTTP headers that can
support the unique identification of Web resources when the sole use of
an URI [RFC3986] may not suffice due to common
content negotiation techniques used by most browsers nowadays. It also
will help to identify complex Web resources like form responses, which
need, for example, information on the POST request used and the sent
parameters. This document is not intended to be a clarification of the
different concepts of the HTTP specification [RFC2616].

Web, ...
The Request class represents an HTTP request. There are eight subclasses derived from the Request class, one for each request type defined in [RFC2616]:
OptionsRequest representing an HTTP Options request,GetRequest representing an HTTP Get request,HeadRequest representing an HTTP Head request,PostRequest representing an HTTP Post request,PutRequest representing an HTTP Put request,DeleteRequest representing an HTTP Delete request,TraceRequest representing an HTTP Trace request,ConnectRequest representing an HTTP Connect request.
The following properties may appear in nodes of type Request.
uriScheme representing the URI scheme (http or https),serverHost representing the host server to connect to,serverPort representing the server port to connect to,absPath representing the absolute path of the URL for the resource to request,version representing the version of HTTP,- header properties.
The Response class represents an HTTP response.
The following properties may appear in nodes of type Response:
responseCode representing the response code sent by the server,- header properties.
The header property represents an HTTP header. There is a property derived from the header property for every header defined in [RFC2616].
The following properties may appear in nodes of type Request:
accept representing an Accept header,accept-charset representing an Accept-Charset header,accept-encoding representing an Accept-Encoding header,accept-language representing an Accept-Language header,authorization representing an Authorization header,expect representing an Expect header,from representing a From header,host representing a Host header,if-match representing an If-Match header,if-modified-since representing an If-Modified-Since header,if-none-match representing an If-None-Match header,if-range representing an If-Range header,if-unmodified-since representing an If-Unmodified-Since header,max-forwards representing a Max-Forwards header,proxy-authorization representing a Proxy-Authorization header,range representing a Range header,referer representing a Referer header,te representing a TE header,user-agent representing a User-Agent header,
The following properties may appear in nodes of type Response:
accept-ranges representing a Accept-Ranges header,age representing an Age header,etag representing an ETag header,location representing a Location header,proxy-authenticate representing a Proxy-Authenticate header,retry-after representing a Retry-After header,server representing a Server header,vary representing a Vary header,www-authenticate representing a WWW-Authenticate header,
The following properties may appear in nodes of type Request or Response:
allow representing an Allow header,cache-control representing a Cache-Control header,connection representing a Connection header,content-encoding representing a Content-Encoding header,content-language representing a Content-Language header,content-length representing a Content-Length header,content-location representing a Content-Location header,content-md5 representing a Content-MD5 header,content-range representing a Content-Range header,content-type representing a Content-Type header,date representing a Date header,expires representing an Expires header,last-modified representing a Last-Modified header,mime-version representing a MIME-Version header,pragma representing a Pragma header,trailer representing a Trailer header,transfer-encoding representing a Transfer-Encoding header,upgrade representing an Upgrade header,via representing a Via header,warning representing a Warning header,
The body property represents an HTTP entity body. It can appear in nodes of both type Request or Response. HTTP bodies are series of bytes, thus we need to translate that to a string of text with a given encoding to make it representable in RDF. The body is then represented by an anonymous Resource with two properties:
bodyContent representing bytes in the entity body,bodyEncoding representing the encoding used to encode the bytes in the entity body.
There are quite a lot of headers used in HTTP, which are not defined in the HTTP/1.1 specification itself. The following lists contain properties for headers listed in [RFC4229].
The following extension properties may appear in nodes of type Request:
accept-additions representing an Accept-Additions header (defined in [RFC2324]),accept-features representing an Accept-Features header (defined in [RFC2295]),a-im representing an A-IM header (defined in [RFC3229]),content-id representing a Content-ID header (defined in [DRP]),cookie representing an Cookie header (defined in [RFC2965]),cookie2 representing an Cookie2 header (defined in [RFC2965]),c-man representing a C-Man header (defined in [RFC2774]),c-opt representing a C-Opt header (defined in [RFC2774]),c-pep representing a C-PEP header (defined in [PEP]),depth representing a Depth header (defined in [RFC2518]),destination representing a Destination header (defined in [RFC2518]),differential-id representing a Differential-ID header (defined in [DRP]),if representing an If header (defined in [RFC2518]),label representing a Label header (defined in [RFC3253]),man representing a Man header (defined in [RFC2774]),negotiate representing an Negotiate header (defined in [RFC2295]),opt representing an Opt header (defined in [RFC2774]),optional representing an Optional header (defined in [WIRE]),ordering-type representing an Ordering-Type header (defined in [RFC3648]),overwrite representing an Overwrite header (defined in [RFC2518]),pep representing a PEP header (defined in [PEP]),position representing a Position header (defined in [RFC3648]),profileobject representing a ProfileObject header (defined in [Ops-OverHTTP]),proxy-features representing a Proxy-Features header (defined in [Proxy Notification]),resolution-hint representing a Resolution-Hint header (defined in [WIRE]),soapaction representing a SoapAction header (defined in [SOAP1.1]),subok representing a SubOK header (defined in [DupSup]),subst representing a Subst header (defined in [DupSup]),surrogate-capability representing a Surrogate-Capability header (defined in [EdgeArch]),ua-color representing a UA-Color header (defined in [UA Attributes]),ua-media representing a UA-Media header (defined in [UA Attributes]),ua-pixels representing a UA-Pixels header (defined in [UA Attributes]),ua-resolution representing a UA-Resolution header (defined in [UA Attributes]),ua-windowpixels representing a UA-Windowpixels header (defined in [UA Attributes]),want-digest representing a Want-Digest header (defined in [RFC3230]).
