general microformats tools
Optimus microformats transformer and validator is a microformats transformer and validator that supports numerous microformats including hCard 1.0, hCalendar 1.0, hReview 0.4 (in progress), hAtom 0.1 (note: hAtom validation issues).
Please add issues to the optimus-issues page.
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.
Rails assert microformats
- George Brocklehurst has written open source code and a post explaining how to do testing microformats in Rails applications with assert-microformats.
microformats specific tools
- 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.
- Try the Technorati Events Feed service.
