Chapter 9. AJAX RSS Reader
In the last few years, the Web has become much more active than it used to be. Today, we see an explosion of new sources of information, such as news sites appearing every day (such as http://www.digg.com and http://www.newsvine.com), and the growing trend of web life—weblogs (every person seems to have a weblog these days).
As a natural reaction to this invasion of information, many systems that allow grouping, filtering, and aggregating this information have appeared. This is implemented in practice through web syndication , which is that form of syndication where parts of a website (such as news, weblog posts, articles, and so on) are made available for other sites or applications to use.
In order to be usable by other parties, the data to be shared must be in a generic format that can be laid out in different formats than in the original source, and when it comes to such formats, RSS 2.0 and Atom are the most popular choices.
