general purpose validators

The following validators will validate multiple microformats on a page:

Optimus

Main article: Optimus microformats transformer and validator

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.

Google Rich Snippets Testing Tool

The Google Rich Snippets Testing Tool can parse several microformats from a given URL and produces reports showing errors and a preview of what properties it detects. It supports a subset of properties on some microformats, however is continuously updated with more support.

microformats: hCard 1.0, hCalendar 1.0, hReview 0.4 (in progress), hRecipe 0.22, hProduct, rel author (and indirectly rel="me")

specific microformats validators

hCard Validator

Operator Debugger

Main article: Operator Firefox plugin

microformats: hCard 1.0, hCalendar 1.0

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?
