It allows you to mark up which elements represent their name, their address, their birthday and so forth.</p> <p>While hCard offers many useful properties that can be used to describe contacts, some are considered beyond the scope of the hCard specification.

By publishing information so that computers can understand it, you make the Web into a huge mine of interconnected data, free to be queried by everyone.</p> <p>As an example of what I mean, searching for the keyword &#8220;train&#8221; on Google brings up results related to:</p> <ul> <li>trains, as a form of transport</li> <li>the band <a href="http://www.trainline.com/">Train</a></li> <li>IT training courses</li> <li>toy trains</li> </ul> <p>In the semantic web, the search engine and my computer would inherently understand the difference between these concepts, so if I wanted to know about the new Train album, I wouldn&#8217;t get any result related to locomotives!</p> <p>What I&#8217;m particularly interested in is ways of embedding semantic data in ordinary web pages, so that we have a single web that can be&#8230;</p>
