Here, the formatted name ("fn"), organisation ("org"), telephone number ("tel") and web address ("url") have been identified using specific class names and the whole thing is wrapped in codice_1, which indicates that the other classes form an hCard (short for "HTML vCard") and are not merely coincidentally named. Other, optional, hCard classes also exist. It is now possible for software, such as browser plug-ins, to extract the information, and transfer it to other applications, such as an address book.
