The hCard microformat standard can be used to represent contact data of people, companies, and organizations
by semantic markup [36]. hCard metadata should be provided on the contact pages of web sites. In summer 2010,
hCard crossed the 2 billion mark according to Yahoo! Search Monkey, making it the most popular metadata format for
people and organizations on the Web.
hCard is based on the vCard standard (RFC 2426 [37]). In fact, existing vCards can be easily converted to hCard. 3
the vCard standard is widely used for storing electronic business cards. For example, Microsoft Outlook uses this
format for the business cards available under Contacts.
The hCard class names should be in lowercase.
the root class name for an hCard is vcard . an element with a class name vcard is itself called an hCard.
3 The vCard notation BEGIN:VCARD is class="vcard" in hCard, N: is class="n" , FN: is class="fn" , and so on.
