microformats are HTML for marking up people, organizations, events, locations, blog posts, products, reviews, resumes, recipes etc. Sites use microformats to publish a standard API that is consumed and used by search engines, browsers, and other web sites. See What are microformats? for more.

  • See microformats2 for a technical overview and summary of how to use microformats on public web pages and for APIs.


Main article: Introduction to Microformats

This wiki is the central resource of the microformats community and provides microformats authoring guides, references, specifications, drafts, publishing patterns, research, brainstorming, and issue tracking.

How to contribute

Want to join in and contribute?

This wiki has a number of enhancements to assist development and contributions to microformats. Before you start editing, see the wiki introduction page for instructions.


microformats2 is stable, has a test suite, publishers, and interoperable implementations. Use it on public web pages and developing more parsers and applications.

Current, stable microformats open standard specifications:

rel microformats

Some microformats require only a rel attribute and are widely supported by consuming sites and software.

Classic Microformats

In addition use well established classic microformats for the primary subject of a page for legacy search engines support.

  • adr - address location information
  • Geo - latitude & longitude location (WGS84 geographic coordinates)


Drafts are classic microformats which have varying degrees of support by consuming applications. They are stable and yet still open to change based on consuming application support, per the The microformats process to become specifications.

  • hNews - news articles, extension of hAtom
  • XMDP - define a microformat vocabulary / profile
  • XOXO - outlines

If you're tempted to try your hand at writing a microformat please read the process page first! and then take a look at Exploratory Discussions for details of prior research, analysis of real-world Best Practices for Examples Pages, existing formats, and brainstorming of possible new microformats, per the microformats The microformats process.

Design Patterns

Design patterns are common uses of markup across microformats.


Past specifications, drafts, and exploratory discussions which have either lacked (or lost) wide publishing support, implementation, or have been superceded by newer specs (see also when does it make sense to demote a microformat spec). These may eventually be retired, deprecated, or reincorporated into other exploratory discussions.



See resources.

User centric development

Shared work areas

Tools, test cases, additional research

The first place to look for examples, code, and test cases is in the pages for each individual microformat. There are only a few cross-cutting tools and services that need to process more than one microformat. That section is intended for editors, Microformats Parsers, microformats validators, test cases, and other information relevant across multiple microformats.


Microformats wiki translations

You may read and edit microformats articles in many other languages:

microformats.org is a community focused on using an empirical (rather than aspirational) The microformats process to research web data & information human publishing behaviors, openly document it on our wiki (http://microformats.org/wiki/), discuss it in #microformats on freenode (irc://irc.freenode.net/microformats), then brainstorm ideas & proposals based on that research for simple formats based on HTML to interoperably represent that information on the web, incrementally implement, and iterate.
