<entry-title>Microformats Implementations</entry-title>

This page lists the applications, plugins, sample code, services, tools that produce or consume microformats.

help improve this page

This is only a partial list. If you know other services or tools for or supporting microformats, please add them to this page, link to their implementors, and list what specific microformats they support.

When you find an implementation:

  1. Make sure that it is an implementation, rather an publishing example (e.g. hCard examples in the wild, hCalendar examples, et.c).
  2. Note the name of the tool or service and the name of the developer(s) who built it.
  3. Add a third level heading with the name of the tool/service to the Applications / Plugins / Services / Tools section below, sorted alphabetically by name of tool/service. e.g.

    === Name of Tool ===

  4. Add a top level list item just below the heading with an external link to the tool/service, along with a link to evidence of their support for microformats, and mention (and locally link) each microformat that is supported. E.g.

    * Link to tool/service, link to their blog post announcing support for e.g. [[hCard]] and [[hReview]]

  5. Add a nested list item and local to wiki hyperlink the Name of Developer to a fragment identifier in the implementors page, e.g. Apple Computer would be linked like this:

    ** by [[implementors#Apple_Computer|Apple Computer]]

  6. Check to see if there is an entry for the developer in the list of implementors, if not add them there. Add a link to the developer's home page followed by "has implemented microformats in:".
  7. In the entry for the developer, add a list item and local to wiki hyperlink the Name of Tool to a fragment identifier in this page, e.g. X2V would be linked like this:

    * [[implementations#X2V|X2V]]

  8. Save the page and make sure that each fragment ID local hyperlink when clicked scrolls you to the right spot (for the developer, and for the tool). Make any fix-up edits as necessary. That's it!

Implementation Details

If there are implementation details worth noting, add them them as nested list items under the item for the implementation itself. If the details subsection grows too big for a specific implementation, feel free to move the details to their own page and leave a link in place on the implementations page.

Reporting Bugs

Similar to implementation details, in short, Put it on the wiki. In particular, add bug reports, with URL(s) to a valid demonstrative test case(s) of course, to the listing of an implementation on this page, OR on the specific implementations wiki page (e.g. hCard Implementations). Please describe why you think it is a bug (user interface, cosmetic, violates a spec page, e.g. for problems parsing hCards, reference which part of hCard parsing the implementation appears to not be following).

If you have a sense of urgency for getting that particular bug fixed in that implementation, you may email microformats-dev with the URL of that implementation on the wiki page, and *summarize* the bug (the full description being on the wiki page instead).


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

In addition, some microformat specifications have separate implementation pages:

Applications / Plugins / Services / Tools

This is an alphabetical listing of all applications, plugins (grouped with their app/tool), services and tools that implement microformats, along with the list of microformats that are supported, and the company and/or developers responsible for it.

As a user, the implementations listed below will automatically help you use microformats and help your data portability and interoperability with other apps and services.

Please help complete this list! If you know of additional apps/plugins/services/tools that support microformats, please add them!

Note: this section is only for listing specific implementations. The list of implementors is in the section on the implementors page.

VIREL Microformats Search Engine




  • Brian Suda has created several XSLT files to extract microformats from HTML. From that the X2V webservice/favelet emerged.

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.
