specific microformats validators

hCard Validators

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?

Optimus validator is not working for the moment

Therefore any page you will check through will return the message: "Microformats at this page have no errors. Congratulations." which is a false message. We will update this message when (and if) Optimus will work again.

Please add issues to the optimus-issues page.
