RSS usage has since spread beyond simple news delivery. Companies like de.licio.us, Flickr and YouTube added another dimension to RSS – i.e. they made it an integral part of the Social Web (social networking, photos, video, etc). Also Google built Google Base, its Craigslist competitor, entirely on RSS. Other companies too are beginning to extend RSS, sometimes with proprietary extensions.
In short, because of RSS ubiquity it is now a very attractive delivery medium for all kinds of content. However because the basic format is simple and primitive, there is no way to encode semantics without building an extension. So in this post, we look at RSS today and ask if RSS is evolving into a tool for delivering complex, semantically rich information.
