<entry-title>Welcome to the microformats wiki!</entry-title>

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.

Introduction

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:

• First, make sure your pages and web apps use semantically rich, descriptive, ‘POSH’ HTML.
• Mark-up your contact info with h-card and link from your personal site to other profiles with rel-me.
• Mark-up your blog with h-entry. See https://indiewebcamp.com/ for more.
• Questions? Read the frequently asked questions, ask on the IRC channel.
• Want to learn more in person? Check out microformats events.

How to contribute

Want to join in and contribute?

• Get started by adding microformats to your website, services, and products
• Join the IRC Channel to learn and help answer questions.
• Write a testimonial
• Do something on the to do list.
• Translate this microformats wiki into other languages to make microformats more accessible to readers of languages around the world.
• Before proposing any new microformats, make sure your website is POSH, uses existing microformats, and then read the process.

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.

Specifications

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:

• h-adr
• h-card
• h-entry
• h-event
• h-feed
• h-geo
• h-item
• h-listing
• h-product
• h-recipe
• h-resume
• h-review
• h-review-aggregate

rel microformats

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

• rel-author - link to the author's home page (from an article)
• rel-enclosure - link to attachments (e.g. files) to download and cache
• rel-license - licensed content
• rel-nofollow - links in untrusted 3rd party content
• rel-tag - tag posts and pages by subject
• XFN - social relationships and rel-me links among profiles for the same person

Classic Microformats

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

• hAtom - blog posts and other date-stamped content
• hCalendar - events
• hCard - people, organizations, contacts
• hListing - listings for products or services
• hMedia - media info about images, video, audio
• hProduct - products
• hRecipe - cooking+baking recipes
• hResume - individual resumes and CVs
• hReview - individual reviews and ratings
• hReview-aggregate - aggregate reviews and ratings

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

Drafts

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 process to become specifications.

• hNews - news articles, extension of hAtom

• rel-home - link to the homepage of a site
• rel-payment - link to a payment mechanism

• 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 examples, existing formats, and brainstorming of possible new microformats, per the microformats process.

Design Patterns

Design patterns are common uses of markup across microformats.

• abbr-design-pattern
• class-design-pattern
• date-design-pattern
• datetime-design-pattern
• include-pattern
• value-class-pattern
• rel-design-pattern

Archived

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.

• hAudio
• robots exclusion
• xFolk - tagged links

• rel-directory - link to web directories
• VoteLinks

Examples

• examples-in-the-wild
• implementations
• zen-garden

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.
