Hcard

The hCard microformat does this using a 1:1 representation of vCard (RFC 2426) properties and values, identified using HTML classes and rel attributes.

It allows parsing tools (for example other websites, or Firefox's Operator extension) to extract the details, and display them, using some other websites or mapping tools, index or search them, or to load them into an address-book program.

In May 2009, Google announced that they would be parsing the hCard, hReview and hProduct microformats, and using them to populate search-result pages. In September 2010 Google announced their intention to surface hCard, hReview information in their local search results. In February 2011, Facebook began using hCard to mark up event venues.

Consider the HTML:

     
Joseph Doe     
Joe     
The Example Company     
604-555-1234     
 href="http://example.com/">http://example.com/  

With microformat markup, that becomes:

 class="">      class="fn">Joseph Doe      class="nickname">Joe      class="org">The Example Company      class="tel">604-555-1234     
 class="url" href="http://example.com/">http://example.com/  

A profile may optionally be included in the page header:

 rel="profile" href="http://microformats.org/profile/"> 

Here the properties fn, nickname, org (organization), tel (telephone number) and url (web address) have been identified using specific class names; and the whole thing is wrapped in class="duhoc-en " which indicates that the other classes form an , and are not just coincidentally named. If the hCard is for an organization or venue, the fn and org classes are used on the same element, as in Wiki or Wembley Stadium. Other, optional, hCard classes also exist.

It is now possible for software, for example browser plug-ins, to extract the information, and transfer it to other applications, such as an address book.

The Geo microformat is a part of the hCard specification, and is often used to include the coordinates of a location within an hCard.

The adr part of hCard can also be used as a stand-alone microformat.
