Microformats Wiki

Hello! Welcome to the microformats wiki. If you haven't already done so, please see the introduction page.

Please read how-to-play before making any edits.

Please read process before proposing any new microformats.

Getting Started

What are microformats? What can you do with them?

The about page, latest news, plus recent press, presentations, books, podcasts, and screencasts are also good places for some background information. Our cheatsheets are handy if you need a quick reminder about a particular microformat. We even have a spell-check dictionary of microformat-related terms.

Frequently asked questions about this wiki and microformats in general are answered in the FAQ, and there is a glossary.

Definition

One popular definition from our mailing list (see also: mailing-lists) is "simple conventions for embedding semantics in HTML to enable decentralized development." More precisely, microformats can be defined as:

simple conventions

for embedding semantic markup

for a specific problem domain

in human-readable (X)HTML/XML documents, Atom/RSS feeds, and "plain" XML

that normalize existing content usage patterns

using brief, descriptive class names

often based on existing interoperable standards

to enable decentralized development

of resources, tools, and services

Simply put: "Microformats are a codification of convention." -- Aaron Gustafson

"Or do you just use your browser to browse? That's so 20th century." -- Mark Pilgrim

Examples

Tools, Test Cases and 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. This section is intended for editors, parsers, validators, test cases, and other information relevant across multiple microformats.
