What is RSS?

   
 

RSS is an acronym of Really Simple Syndication (sometimes referred to as Rich Site Summary). RSS is a set of XML communication standards created by Netscape. RSS allows a web developer to share the content on his/her site with other developers and anyone who can read the RSS file. RSS repackages the web content as a list of data items, to which one can subscribe from a directory of RSS publishers. RSS content usually includes news stories, headlines, content from discussion lists, or corporate announcements and is primarily used by news sites and weblogs.
Once a feed is available, application can regularly fetch the file to get the most recent items.
