RSS (Rich Site Summary)

RSS (RDF Site Summary or Really Simple Syndication) is a lightweight, XML-based format for feeds of information. Generally used for information that is updated on a regular basis, such as news headlines, although it is very flexible and can be used for many types of information.

Because it is lightweight and generally more efficient than a full web page (or even a mobile page), it is ideal for mobile devices where bandwidth and screen size are limited.

RSS-reader software is available for most smartphones.

A standard XML file format ensures compatibility with many different machines/programs. RSS feeds also benefit users who want to receive timely updates from favourite websites or to aggregate data from many sites.

RSS feed data is presented to users using software called a news aggregator. This aggregator can be built into a website, installed on a desktop computer, or installed on a mobile device. Users subscribe to feeds either by entering a feed's URI into the reader or by clicking on the browser's feed icon. The RSS reader checks the user's feeds regularly for new information and can automatically download it, if that function is enabled. The reader also provides a user interface.
