RSS Feed
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
or desktop-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 the feed's URI (often referred to informally as a "URL",
although technically, those two terms are not exactly synonymous) into
the reader 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.
