Requesting a MIME Media Type for RSS

In March, a member of Microsoft's Internet Explorer team asked the RSS Advisory Board for a recommendation on the MIME media type for RSS documents.

One of the most reliable ways for software to distinguish different kinds of files on the Internet is through a media type, an identifier that's part of the Multipurpose Internet Mail Extensions standard.

Web servers return a Content-Type header that identifies the kind of file being returned, such as "text/html" for an HTML page, "image/gif" for a GIF graphics file, and "application/atom+xml" for Atom syndicated feeds.

RSS documents lack an an official media type.

If a media type was defined for RSS, when a user opened an RSS feed in a web browser, the browser could open the document with the user's preferred software -- just as browsers crank up an MP3 player when a link to an MP3 is clicked.

Media types must be requested from the Internet Assigned Numbers Authority with a formal RFC that chooses the desired type, explains the nature of the content, and describes why the type is needed.

The advisory board is teaming up with the RSS-DEV Working Group, the developers of RSS 1.0, on a shared request for a media type.

Jon Hanna, Bill Kearney, Greg Smith and I have prepared an application to request "application/rss+xml" as the official media type for RSS documents.

We're floating a proposal to both groups to support this media type and encourage its use for all versions of RSS, whether they use RDF Site Summary or Really Simple Syndication.


With MIME RSS will not bee Really Simple Syndication :( atleast for PHP developers
