specific microformats validators

hCard Validator

• The unofficial hCard Validator
  • It's open-source and contributions are welcome! Please join the project and extend it to support more microformats.

Operator Debugger

Main article: Operator

• https://addons.mozilla.org/firefox/4106/

microformats: hCard, hCalendar

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

rel-lint

Rel-Lint provides linting and inspection of rel-tag and XFN (by Drew McLellan)

validator project

There has been a suggestion to host an "official" microformats validator at microformats.org.

Ideas:

• hCard validator is open-source (BSD-licensed) and extensible enough to support other microformats (it's mostly a matter of hooking up XSLT templates that extract microformat data and find errors). The codebase is pretty clean, UI is internationalized.

Who wants to help make this happen, and what do you need?
