representative hCard

This page is for keeping track of the representative hCard effort, which is part of hcard-brainstorming, specifically to figure out how to both explicitly specify and discover the representative hCard for a page.

problem statement

Short version: Given a URL, how do you determine which hCard is the representative hCard for that page?

Longer: Given a URL to a page that represents a person, how do you determine which hCard on that page is the hCard for that person? Variants:

use cases

Applications for auto-discovery of the representative hCard for the page

  • representative vCard auto extraction from the page
  • profile icon discovery (e.g. what people use gravatar for and have proposed pavatar for).
  • social-network-portability

goals

  • should leverage current hCard information publishing patterns
  • should not require any additional user interface elements (i.e. links) on any hCard supporting user profiles.

methodology

Methodology for a solution: The preferred option is to use only visible semantic HTML (POSH).

effort

related

Related but slightly different concepts:

  • contact for the page. similarly, the person a page represents is usually the person to contact for/about the page. as documented in the hCard FAQ, the contact for a page SHOULD be marked up with an <address> hCard.
  • author hCard. typically the person that a page represents is also the author of the page. possible (theoretical until someone finds/cites real world) examples: biographies, e.g. a page that represents person A is authored by person B.
  • owner hCard. more often than not, the person that a page represents is also the person that owns (meaning has primary control over, in the property sense) the page.
