OpenId + Microformats Brainstorming

This is a public space for capturing some ideas on how OpenId and Microformats can work together.

Relevant Microformats

• hCard - for profiles
• XFN
  • rel="friend" etc. for marking up relationships between profiles
  • rel="me" for identity consolidation among profiles
    • Should Yadis be extended to support rel="me"?

Ideas for use

• Identity providers could provide hCard marked up profile pages
• re-use hCard (vCard) vocabulary for HTTP query based key-value pairs of information requested and returned

Microformats outside HTML

• JSON representations of hCard etc.

OpenID whitelist authentication for private hCard

A possible design pattern is to use OpenID to allow a person to login to, say, a blog and find out more information. You could build the whitelist of OpenID's by parsing data out of a social network API or a list of XFN friends (following the ideas on social-network-portability).

Tom Morris has implemented this on his blog, and on a "family extranet".
