RSS is a family of web feed
formats used to publish frequently updated works such as
blog
entries, news headlines, audio, and video in a standardized
format. An RSS document (which is called a "feed", "web feed",
or "channel") includes full or summarized text, plus metadata
such as publishing dates and authorship. Web feeds benefit
publishers by letting them syndicate content automatically. They
benefit readers who want to subscribe to timely updates from
favored websites or to aggregate feeds from many sites into one
place. RSS feeds can be read using software
called an "RSS reader", "feed reader", or "aggregator",
which can be web-based,
desktop-based,
or mobile-device-based. A standardized XML file
format allows the information to be published once and viewed by
many different programs. The user subscribes to a feed by
entering into the reader the feed's URI or by
clicking an RSS icon in a browser that initiates the
subscription process. The RSS reader checks the user's
subscribed feeds regularly for new work, downloads any updates
that it finds, and provides a user interface
to monitor and read the feeds.
