What is RSS?
RSS (Really Simple Syndication) is a technology that is being used by millions of web users around the world to keep track of their favorite websites. In the ‘old days’ of the web to keep track of updates on a website you had to ‘bookmark’ websites in your browser and manually return to them on a regular basis to see what had been added.
History of RSS Feed
The name “RSS” is an umbrella term for a format that spans several different versions of at least two different (but parallel) formats. The original RSS, version 0.90, was designed by Netscape as a format for building portals of headlines to mainstream news sites. It was deemed overly complex for its goals; a simpler version, 0.91, was proposed and subsequently dropped when Netscape lost interest in the portal-making business. But 0.91 was picked up by another vendor, UserLand Software, which intended to use it as the basis of its web-logging products and other web-based writing software.
In the meantime, a third, non-commercial group split off and designed a new format based on what they perceived as the original guiding principles of RSS 0.90 (before it got simplified into 0.91). This format, which is based on RDF, is called RSS 1.0. But UserLand was not involved in designing this new format, and, as an advocate of simplifying 0.90, it was not happy when RSS 1.0 was announced. Instead of accepting RSS 1.0, UserLand continued to evolve the 0.9x branch, through versions 0.92, 0.93, 0.94, and finally 2.0.
How does RSS work?
RSS works by having the website author maintain a list of notifications on their website in a standard way. This list of notifications is called an “RSS Feed”. People who are interested in finding out the latest headlines or changes can check this list. Special computer programs called “RSS aggregators” have been developed that automatically access the RSS feeds of websites you care about on your behalf and organize the results for you. (RSS feeds and aggregators are also sometimes called “RSS Channels” and “RSS Readers”.)
Producing an RSS feed is very simple and hundreds of thousands of websites now provide this feature, including major news organizations like the New York Times, the BBC, and Reuters, as well as many weblogs. RSS has become an integral part of internet marketing.
