Help:Microformats

Microformats allow us to label certain types of ordinary text content on Wikipedia pages so that software can recognise and process it. You'll find microformats on lots of other leading websites, too, such as The BBC, Facebook, LinkedIn and Upcoming.

Our use of microformats make it possible for your computer to extract such information from Wikipedia articles and then re-use it in other websites (to, say, convert, aggregate or chart it), or in computer programs (such as your calendar or address book, or Google Earth).
