RSS
is a family of web feed formats, specified in XML
and used for Web syndication. RSS is used by (among
other things) news websites, weblogs and podcasting.
Web feeds provide web content or summaries of web
content together with links to the full versions of
the content, and other metadata. RSS in particular,
delivers this information as an XML file called an
RSS feed, webfeed, RSS stream, or RSS channel. In
addition to facilitating syndication, web feeds allow
a website's frequent readers to track updates on the
site using an aggregator.
Web feeds are widely used by the weblog community
to share the latest entries' headlines or their full
text, and even attached multimedia files. (See podcasting,
vodcasting, broadcasting, screencasting, Vloging,
and MP3 blogs.) Since mid-2000, use of RSS has spread
to many of the major news organizations, including
Reuters, CNN, PR Newswire, and the BBC. These providers
allow other websites to incorporate their "syndicated"
headline or headline-and-short-summary feeds under
various usage agreements. RSS is now used for many
purposes, including marketing, bug-reports, or any
other activity involving periodic updates or publications.
Many corporations are turning to RSS for delivery
of their news, replacing email and fax distribution.
