The identification of resources on the Web by URI may not be sufficient to uniquely resolve a document as other factors such as HTTP content negotiation might come into play. This issue is particularly significant for quality assurance testing, conformance claims, and reporting languages like the Evaluation and Report Language (EARL). This document describes a representation of HTTP vocabulary in RDF. The terms defined by this document allow HTTP headers that have been exchanged between a client and a server to be recorded in RDF format. The terms defined by this document includes vocabulary for HTTPS as well as other extensions to the core specification.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
This W3C First Public Working Draft of the HTTP Vocabulary in RDF document was published on 20 December 2006 by the Evaluation and Repair Tools Working Group (ERT WG). This document is expected to be published as a W3C Working Group Note after review and refinement, potentially upon the next publication.
The working group encourages feedback about the approach, as well as about the completeness and maturity of this document by developers and researchers who have interest in a representation of the HTTP vocabulary in RDF format. Feedback from the W3C Quality Assurance Interest Group (QA IG), the W3C Semantic Web Interest Group (SWIG), and the W3C Mobile Web Best Practices Working Group (BPWG) is particularly welcome. Please send comments on this document to the public mailing list of the working group public-wai-ert@w3.org. The archives of the working group mailing list are publicly available.
Publication as a Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. The group does not expect this document to become a W3C Recommendation. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent.

This document presents a representation of the Hyper Text Transfer Protocol (HTTP) using the Resource Description Framework (RDF). It defines a collection of RDF classes and properties that represent the HTTP vocabulary as defined by the HTTP specification. These RDF terms can be used to record HTTP request and response messages in RDF format. For example by automated Web accessibility evaluation tools to describe Web resources, including the various headers exchanged between the client and server during content negotiation. More usage examples for these terms are described in section 1.2. Use Cases.
This document is not inteded to be a clarification of the different concepts of the HTTP specification. The HTTP specification is defined by a series of Request for Comments (RFC) and other documentation. These are listed in Appendix C. References. This document is also not intended to be an introduction to RDF, refer to [RDF] or [RDF-PRIMER] for this purpose.
The RDF representation of the HTTP vocabulary defined by this document uses three different namespaces:
Vocabulary | Namespace URI | Prefix |
---|---|---|
HTTP | http://www.w3.org/2006/http# |
http (default namespace) |
URI | http://www.w3.org/2006/uri# |
uri |
RFC 822 | http://www.w3.org/2006/rfc822# |
rfc822 |
The following (non-exhaustive) list of use cases aims to highlight some of the different usages of this vocabulary:
This section defines RDF terms for the basic HTTP 1.1 specification according to [RFC 2616].
The Request
class represents an HTTP request. There are eight subclasses derived from the Request
class, one for each request type defined in [RFC 2616]:
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, andConnectRequest
representing an HTTP Connect request.The following properties may appear in nodes of type Request
:
uri:uri
representing the URI as defined in [RFC 3986] (see also 2.5. URI Property),version
representing the version of HTTP,header
properties (see 2.3. Header Properties and 3. Header Extensions),additionalHeader
properties (see 4. Field Messages), andbody
representing the message body (see 2.4. Body Property).Example 2.1: A GetRequest
object.
<http:GetRequest> <uri:uri>http://www.example.org:80/</uri:uri> <http:version>1.1</http:version> <http:accept>text/html;q=1.0, */*;q=0.01</http:accept> <http:accept-language>de-DE;q=1.0, de;q=0.75, en-GB;q=0.5, en;q=0.25, *;q=0.01</http:accept-language> </http:GetRequest>
The Response
class represents an HTTP response as defined in [RFC 2616]. The following properties may appear in nodes of type Response
:
responseCode
representing the response code sent by the server,header
properties (see 2.3. Header Properties and 3. Header Extensions),additionalHeader
properties (see 4. Field Messages), andbody
representing the message body (see 2.4. Body Property).Example 2.2: A Response
object.
<http:Response> <http:content-type>text/html;charset=utf-8</http:content-type> <http:vary>accept, accept-language</http:vary> <http:body><![CDATA[aksgbq3833o3gbo4zgblakc8t9ut2]]></http:body> </http:Response>
The header
property represents an HTTP header. There are additional properties derived from the header property; every sub-property refers to a header defined in [RFC 2616].
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, anduser-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

and 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 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, andwarning
representing a Warning header.The body
property represents an HTTP entity body as defined in [RFC 2616]. It can appear in nodes of both type Request
or Response
. HTTP bodies are series of bytes. Thus they MUST be translated to a string of text using the Base64 encoding scheme to make it representable in RDF.
Example 2.3: The body
property.
<http:body><![CDATA[aksgbq3833o3gbo4zgblakc8t9ut2]]></http:body>
The uri
property describes a Uniform Resource Identifier as defined in in [RFC 3986]. Since URIs are not restricted to HTTP, this property resides in its own namespace.
Example 2.4: The uri
property.
<uri:uri>http://www.example.org:80/</uri:uri>
There are quite a lot of headers used in HTTP, which are not defined in the HTTP 1.1 specification (RFC 2616) itself. This section defines properties for header extensions according to [RFC 4229].

The serialization of HTTP messages in RDF format brings about a significant limitation regarding the order of header information. According to the RDF model, the order in which properties are serialized is not relevant. However, the order in which HTTP headers are exchanged between the client and the server can be significant. For example the following sequence of headers describes a specific content encoding, namely "compress" after "gzip":
content-encoding: gzip
content-encoding: compress
To keep the schema defined by this document simple, sequences of HTTP headers of the same type MUST be serialized in a single RDF property using a comma separated string as defined by [RFC 2616]. The order of the individual header values MUST reflect the order in which they were exchanged. For example, the sequence of headers from above must be represented in the following way:
<http:content-encoding>gzip, compress</http:content-encoding>
Editor's Note: are there cases in which the order of different header types can be significant? The working group has not identified any such restrictions.
There are also noteable schema limitations with regards to security and privacy since the content recorded by this vocabulary could potentially contain sensitive information. For example authentication information in HTTP headers or other information (login user name, passwords, etc.) within the body of the message. Since the schema of this document is limited to terms defined by the HTTP vocabulary, security and privacy considerations need to be made at the application level. For example, certain parts of the data may be restricted to appropriate user permissions or obfuscated.
The following example shows an RDF/XML representation of an HTTP request and response pair.
A client requests a resource in the document root (/
) at www.example.org
port 80 via HTTP 1.1. With the request, it sends request headers. The server uses content negotiation. Some of the request headers (accept
and accept-language
) are relevant for the creation or choice of the result as indicated by the vary
reponse header. Thus, at least these request headers are recorded in the representation of the request. In addition to the content-type
and vary
headers, the server sends an unknown header (x-foo
) which appears as a Field Message as specified by [RFC 822]. The bodyContent
property contains the result of a Base64 transformation of the returned byte sequence.
