What are Microformats?
-
Microformats enable the publishing and sharing
of higher fidelity information on the Web.
- Building blocks that enable users to own, control, move, and share their data on the Web.
-
Small bits of (X)HTML that identify richer data types
like people and events in your webpages.
- The fastest and simplest way to provide an API for your website.
-
More than just "good class names"
- principles keep things "micro"
- process emphasizes getting real
- community minimizes duplicates
-
Microformats Principles
- solve a specific problem
-
The trick.... is to make sure that each limited mechanical part of the Web, each application, is within itself composed of simple parts that will never get too powerful.
- —Tim Berners-Lee, Weaving The Web
-
Microformats Principles
- solve a specific problem
- simple as possible
- evolutionary improvements
- humans first, machines second
- presentable and parsable
- adapt to current behaviors
- reuse from widely adopted standards
- semantic (X)HTML, schemas from interoperable RFCs
-
...if I had insisted everyone use HTTP, this would also have been against the principle of minimal constraint. ... the Web would come as a set of ideas that could be adopted individually in combination with existing or future parts.
- ibid.

- evolutionary improvements
- humans first, machines second
- presentable and parsable
- adapt to current behaviors
- reuse from widely adopted standards
- semantic (X)HTML, schemas from interoperable RFCs
- modularity / embeddability
- decentralized development, content, services
- explicitly encourage "spirit of the Web"
-
- Analogy: link to a stylesheet with rel="stylesheet"
- Thus: link to a license with rel="license"

- document existing formats in the problem area
- brainstorm with implied schema / reuse names
- iterate within the community
