RSS - RDF Site Summary aka Rich Site Summary aka Really Simple Syndication

An RSS 2.0 document, called a "feed", "web feed", or "channel", contains either full text or a summary of content from a linked website. It is an easy way to keep up with new information on the user's chosen websites. e.g. feeds can be sent directly to a user's inbox.

Rich Site Summary (RSS 0.91)

RDF - Resource Description Framework is a family of W3C specifications which integrate various applications and events using XML as an interchange syntax.

• In 1997 Dave Winer at UserLand designed the XML syndication format scriptingNews.

• In 1999 the World Wide Web Consortium (W3C) published their specifications for the RDF format RSS 0.90.

• In 1999 Netscape designed RSS 0.90 for use with my.netscape.com, which also supported scriptingNews format.

• UserLand took up the RSS 0.91 dropped by Netscape and went on to design 0.92/3/4 and RSS 2.0.

• In 2000 the RSS-DEV Working Group, a private, non-commercial working group released its own set of specifications called RSS 1.0.

• In 2003, Winer and UserLand Software assigned the copyright of the RSS 2.0 specification to Harvard's Berkman Center for the Internet & Society.
