Definition RSS

RSS (Really Simple Syndication is the most accepted definition) is a family of web-feed formats used to publish frequently updated digital content such as news feeds or blogs. A Web feed is a data format used for serving users who frequently update their digital content, which can be syndicated thereby allowing users to subscribe to it.

Its value lies in the fact that by way of software known as 'feed aggregators', users can to subscribe to web feeds. Aggregators reduce the time a user needs to stay online to perform tasks, such as get news or blog updates, that they do on a regular basis. By way of the user's aggregator software the sites the users wants to regularly check on are combined into a "personal newspaper" where all updates are announced. These sites need to have an RSS feed in order for this to happen.

In order for a site to be accessed by RSS feed the language used to write it must be XML.
