RSS allows lists of information to be exchanged in an XML-based format. Nottingham Expires April 23, 2002 [Page 1] 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: Nottingham Expires April 23, 2002 [Page 2] Internet-Draft The application/rss+xml Media Type October 2001 The security considerations outlined in RFC3023 [1] apply. Published specification(s): RSS 0.9 [2] RSS 0.91 [3] RSS 0.92 [4] RSS 1.0 [5] Applications which use this media type: RSS editors, producers and aggregators. 2.1 Additional information: Magic number(s): There is no single initial byte sequence that is always present in RSS files.
