Internet-Draft The application/rss+xml Media Type October 2001
1. Introduction
RSS is a lightweight, multipurpose, extensible metadata description
and syndication format. RSS is an XML application.
RSS is currently used for a number of applications, including news
and other headline syndication, weblog syndication, and the
propogation of software update lists. It is generally used for any
situation when a machine-readable list of textual items and/or
metadata about them needs to be distributed.
There are a number of revisions [2][3][4][5] of the RSS format
defined, many of which are actively used. This memo defines a media
type, application/rss+xml for all versions of RSS.
2. Registration Information
To: ietf-types@iana.org
Subject: Registration of MIME media type application/rss+xml
MIME media type name: application
MIME subtype name: rss+xml
Required parameters: none
Optional parameters:
charset
Same as charset parameter of application/xml as specified in
RFC3023 [1].
revision
The optional revision parameter indicates the version of RSS used;
the value is specified by the target RSS version. In practice,
this value should be an XML Namespace [6], if defined (e.g.,
'http://purl.org/rss/1.0/' for RSS 1.0), or a revision number if
not (e.g., "0.92" for RSS 0.92).
Encoding considerations:
Same as encoding considerations of application/xml as specified in
RFC3023 [1].
Security considerations:
