hCard advocacy

Adding hCard to these sites would make them quite handy for their users and for being indexed:

Online Profiles

User Profiles

Nearly every website that has a login has a page representing the public profile of the user that other users can see and interact with. Many such sites already support hCard (e.g. ClaimID.com, Flickr.com, Technorati.com). Here are some that I think would benefit from the addition of hCard to their profile / user pages, making them hCard supporting user profiles. In addition, if such profiles have friends lists, we should encourage them to add support for hCard+XFN supporting friends lists. Both of these help social-network-portability and help the site become a node on the social-network-portability.

Feel free to add more such sites that have a social network profile-like component and we'll see what we can do. Tantek 17:44, 13 Dec 2006 (PST)

Company Profiles

Online Venues

There are many sites that offer pages that represent organizations and venues that could benefit from being marked up with hCard. Yahoo Local venues are marked up with hCards for example. Here are some more sites that have venues that would benefit from hCard markup.

  • Yelp.com
  • http://opentable.com - a site for making restaurant reservations
    • hCard for restaurants
    • hCalendar for free busy times at restaurants
    • hCalendar for your reservations
    • Tantek has emailed a friend who is a former employee of OpenTable with the above three requests, in the hopes she can pass on the message. In addition, Ryan King may know someone in marketing there. Tantek 16:57, 30 Sep 2007 (PDT)

Plugins for and modifications of web-applications

Many web-applications use plugin-systems to change their behavior and content. Most notable is probably web-forums and blogs. Many of these have a community of coders that develop plugins or code to modify the default behavior of these web-applications. Here are some sites where it might be interesting to develop hcard-related plugins/mods.

Telephone Directory Listings

Telephone Directory Listings could usefully apply hCard to their results pages, e.g. (please add other examples!):

Postal (ZIP) code Finders

Postal code Finders could usefully apply hCard to their results pages. Andy Mabbett 12:09, 13 Nov 2006 (PST)

e.g. (please add other examples!):

Government hCard

UK Gov. hCard

Europe Gov. hCard


http://maplight.org/ can use a bunch of hCard markup, e.g.

Organization Contacts

Many companies and organizations have about or contact pages that could benefit from being marked up with hCard. Technorati's contact page for example is both marked up with hCard and has a convenient "Add to Address Book" hCard to vCard converter link. The following company sites could benefit from similar markup (and, until user agents support hCards natively, "Add to Address Book" links). Tantek 17:44, 13 Dec 2006 (PST)

Individual hCards

Getting these sites to at least add hCard to their home page or contact info page and then ping Pingerati would be an excellent start with getting them some experience with microformats and thinking about adding microformats to other places in their sites that make sense:

Trade directories

Other hCard


Wikpedia hCard

Some microformat data is now (2007-09-14) being removed from Wikipedia; see, for example List_of_Gaudi_Buildings

The hCard specification is a work in progress. As additional aspects are discussed, understood, and written, they will be added. These thoughts, issues, and questions are kept in separate pages.
