Its name is an acronym for Really Simple Syndication.

RSS is a dialect of xml. All RSS files must conform to the XML 1.0 specification, as published on the World Wide Web Consortium (W3C) website.

A summary of RSS version history.

At the top level, a RSS document is a <rss> element, with a mandatory attribute called version, that specifies the version of RSS that the document conforms to. If it conforms to this specification, the version attribute must be 2.0.

Subordinate to the <rss> element is a single <channel> element, which contains information about the channel (metadata) and its contents.

Sample files RSS 2.0 Specification(圖一)

Here are sample files for: RSS 0.91, 0.92 and 2.0.

Note that the sample files may point to documents and services that no longer exist. The 0.91 sample was created when the 0.91 docs were written. Maintaining a trail of samples seems like a good idea.
