Microformats Implementors And Implementations

This page lists the companies, applications, services, and sample code which support microformats, along with the developers responsible for doing so that have chosen to be listed. This is only a partial list. If you know other companies implementing microformats, please add them and list their services and what specific microformats they support.

By Format

Most microformat specifications have an "implementations" section, e.g.:

In addition, some microformat specifications have separate implementation pages:

By Tool

By Company / Organization / Author


  • Avon - publishes all 40,000+ Avon representatives' contact info with the hCard microformat.






Ice Rocket

Iowa Military Veterans Band

Laughing Squid




Sunnyvale House Concerts


  • - hCalendar support in events listings and individual events.

University of Bath

Web Essentials


  • WordPress supports XFN blogrolls through a very nice built-in user interface.


brian suda has created several XSLT files to extract microformats from HTML. From that the X2V webservice/favelet emerged. The XSLT and favelet extracts hCard and to produces .vcf (vCard) files and hCalendar to produce .ics (iCal) files. Also in the labs is a universal XMDP validator and a site-wide search spider that recognizes 'no-follow', 'license' and other microformats so they can be used in a more semantic way when displaying search results.


  • rfc2629.xslt now attempts to generate hCard information (RFC2629 is an XML format for authoring RFCs and Internet Drafts, see example document)
  • Andy Hume uses the hcard format to mark-up the names and URLs of commentors on his blog.
  • JSCalendar parses hCalendar and produces a displayable HTML table/CSS-based calendar.
