RSS is a family of data formats used to publish 'feeds' containing news or detailed up updated content on the web. RSS stands variously for "Really Simple Syndication" (RSS 2.0), "RDF Site Summary" (RSS 1.0 and RSS 0.90), and "Rich Site Summary" (RSS 0.91).
Autodiscovery
The RSS standards now feature an autodiscovery method: where the inclusion of certain tags within an html page can point you to the RSS feed of that page.
