All Microformats

Optimus Validator

• http://microformatique.com/optimus/

As well as a transformer, Optimus has a validator/conformance-checker mode, flagging errors in microformat mark-up. It's not 100% accurate (as of 2009-05-15), but still provides valuable debugging feedback.

Operator Debugger

• [1]

Operator does a good job of compliant parsing for microformats in general, and includes a debug mode that can help identify errors in the object structure.

rel-lint

• [2]

Rel-Lint supports validation and inspection of rel-tag and XFN (by Drew McLellan)

hCard Tools

• http://hcard.geekhood.net/
• Also try the Technorati Contacts Feed service.
• The Cognition web service includes hCard error messages and warnings using EARL as part of the RDF output — hopefully other microformats will be covered in the near future.

hCalendar

• Try the Technorati Events Feed service.
