Microformats

Microformats are an HTML standard that express people, events, reviews, recipes, datestamped content, and other structured data in web pages in a way that makes them easily usable by web browser, search engines, and other web crawlers.

Web browsers in particular are able to associate the data with particular actions and provide a richer user experience for pages marked up with microformats.

Common Microformats

• h-card - people and organizations
• h-event - events
• h-review - reviews of places, people, events, products, etc.
• h-entry - blog posts, status updates, and any kind of episodic content
• h-adr - structured addresses
• h-geo - latitude/longitude geolocations
• see http://microformats.org/wiki/ for more.

Projects

• microformats2-parsing

Platform

Firefox has some microformats parsing support in the Toolkit "product", microformats "component":

• open bugs for Firefox microformats support

In addition there is active in-progress work to land microformats2-parsing support to support Social API use-cases:

• 1037483 - update firefox microformats parser with microformats2 support - in progress

Use Cases

Enhance existing Firefox features:

• Firefox Share (airplane) button in toolbar
• Social Bookmarking: Microformats can be passed to bookmarking, read-it-later, etc. style services like Pinterest's "rich pinning" of objects in the page.
• Context Menu: right-click on microformats such as
  • h-card for "Add to Contacts"
  • h-event for "Add to Calendar"
  • h-adr & h-geo for "View in Map"
• Live Bookmarks / RSS Discovery and Preview (would enable Bug 543630)

Support new planned Firefox OS features:

• FirefoxOS (Gaia/System/Microformats)

Future / potential features:

• Shopping: Microformats such as h-review, h-product, and h-listing support rich markup of products, useful in shopping carts, watching products for updates, product comparison shopping, etc.
• Automatically detecting venues, people, contacts, events, locations and integrating with built-in contacts, calendar, and mapping user interfaces.

Benefits

• Better control by content producers
• Easy manipulation of data by clients without server side involvement
• Accurate data collection by services
