RSS (most commonly expanded as "Really Simple Syndication") 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. (For more information on RSS, see
