microformats are extensions to 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, aggregators, and other tools. See what-are-microformats for more.



Main article: introduction

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.

Get Started

Main article: get-started

Get started with microformats:

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.


The list of current, stable Microformats open standard specifications.


Drafts are newer microformats, which are still making their way through the process to become specifications. Implementers should be prepared to keep abreast of future developments and changes. Please watch the wiki pages for updates.

If you're tempted to try your hand at writing a microformat please read the process page first!

Exploratory Discussions

Main article: exploratory-discussions

New: microformats 2 has sufficiently stabilized to start using on public web pages and developing parsers and applications.

See: exploratory-discussions for details of research and analysis of real-world examples, existing formats, and brainstorming of possible new microformats, per 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and exploratory discussions which have either lacked (or lost) wide publishing support, implementation, or have been superceded by newer specs (see also when does it make sense to demote a microformat spec).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, parsers, validators, test cases, and other information relevant across multiple microformats.


Microformats wiki translations

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