hCard examples in the wild, with problems

This page is an informative section of the hCard specification.

The following sites have published hCards, which are either invalid or problematic.

Guidelines for use

Entries may be moved here if there's a problem with the way hCards are used on the page concerned. If the page is yours, and you want to improve it, see the hCard FAQ, or raise any queries on hCard Issues or the mailing list, where people will be happy to help you.

Please consider distinguishing problems as:

• invalid - the hCard is invalid and cannot be parsed by a parser for any information due to the problem.
• suboptimal - the hCard is technically valid, yet either has one or more properties that have no data due to a markup problem (e.g. adr without children), and/or there is data inside the hCard markup which could be marked up with an hCard (sub)property but isn't.
• hidden - one or more of the hCard's (sub)properties are hidden via CSS or other mechanism and are thus potentially out-of-date or vulnerable to being labelled as spam by search engines.

Examples with problems

• Airfix Stockists and Distributors, e.g. [1]
  • suboptimal: street-address contains street address, locality and region (e.g. "99 Hobs Moat Rd, Solihull, W. Midlands")
  • suboptimal: postal-code and country-name include preprended commas
  • suboptimal: fn is used; should be fn org

  • invalid The "n" property is empty, that is, it has no explicit sub-properties, which is not allowed. Possible fixes to the content: explicitly markup 'given-name' and 'family-name', or just remove 'n' property from the markup and let 'fn' implied 'n' rule take effect.
