RSS (file format) – Wikipedia, the free encyclopedia: RSS stands for Really Simple Syndication.
In simple words, the technology of RSS allows Internet users to subscribe to websites that have provided RSS feeds; these are typically sites that change or add content regularly. To use this technology, site owners create or obtain specialized software (such as a content management system) which, in the machine-readable XML format, presents new articles in a list, giving a line or two of each article and a link to the full article or post. Unlike subscriptions to many printed newspapers and magazines, most RSS subscriptions are free.
The RSS formats provide web content or summaries of web content together with links to the full versions of the content, and other meta-data. This information is delivered as an XML file called an RSS feed, webfeed, RSS stream, or RSS channel. In addition to facilitating syndication, RSS allows a website’s frequent readers to track updates on the site using an aggregator.
How can I use RSS?
RSS is widely used by the weblog community to share the latest entries’ headlines or their full text, and even attached multimedia files. RSS is now used for many purposes, including marketing, bug-reports, or any other activity involving periodic updates or publications.
A program known as a feed reader or aggregator can check RSS-enabled webpages on behalf of a user and display any updated articles that it finds. It is now common to find RSS feeds on major Web sites, as well as many smaller ones.
Client-side readers and aggregators are typically constructed as standalone programs or extensions to existing programs like web browsers. Such programs are available for various operating systems.
Web-based feed readers and news aggregators require no software installation and make the user’s “feeds” available on any computer with Web access. Some aggregators syndicate (combine) RSS feeds into new feeds, e.g. take all football related items from several sports feeds and provide a new football feed. There are also search engines for content published via RSS feeds like Feedster, Blogdigger or Plazoo.
On Web pages, RSS feeds are typically linked with an orange rectangle optionally with the letters XML or RSS.
