Abstract
This document describes a media type (application/rdf+xml) for use
with the Extensible Markup Language (XML) serialization of the
Resource Description Framework (RDF). RDF is a language designed to
support the Semantic Web, by facilitating resource description and
data exchange on the Web. RDF provides common structures that can be
used for interoperable data exchange and follows the World Wide Web
Consortium (W3C) design principles of interoperability, evolution,
and decentralization.

RFC 3870 application/rdf+xml September 2004
1. Introduction
RDF is a language designed to support the Semantic Web, by
facilitating resource description and data exchange on the Web. RDF
provides common structures that can be used for interoperable data
exchange and follows the W3C design principles of interoperability,
evolution, and decentralization.
While the RDF data model [2] can be serialized in many ways, the W3C
has defined the RDF/XML syntax [1] to allow RDF to be serialized in
an XML format. The application/rdf+xml media type allows RDF
consumers to identify RDF/XML documents so that they can be processed
properly.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14, RFC 2119 [6].
2. application/rdf+xml Registration
This is a media type registration as defined in RFC 2048,
"Multipurpose Internet Mail Extensions (MIME) Part Four: Registration
Procedures" [5].
MIME media type name: application
MIME subtype name: rdf+xml
Required parameters: none
Optional parameters: charset
Same as charset parameter of application/xml, defined in RFC
3023 [4].
Encoding considerations:
Same as charset parameter of application/xml, defined in RFC
3023 [4].
Security considerations:
See "Security Considerations" (Section 6).

RFC 3870 application/rdf+xml September 2004
Interoperability considerations:
It is RECOMMENDED that RDF documents follow the newer RDF/XML
Syntax Grammar [1] as opposed to the older RDF Model and Syntax
specification [7].
RDF is intended to allow common information to be exchanged
between disparate applications. A basis for building common
understanding is provided by a formal semantics [3], and
applications that use RDF should do so in ways that are
consistent with this.
Published specification:
see RDF/XML Syntax Grammar [1] and RDF: Concepts and Abstract
Syntax [2] and the older RDF Model and Syntax [7]
Applications which use this media type:
RDF is device-, platform-, and vendor-neutral and is supported
by a range of Web user agents and authoring tools.
Additional information:
Magic number(s): none
Although no byte sequences can be counted on to consistently
identify RDF, RDF documents will have the sequence
"http://www.w3.org/1999/02/22-rdf-syntax-ns#" to identify
the RDF namespace. This will usually be towards the top of
the document.
File extension(s): .rdf
Macintosh File Type Code(s): "rdf "
