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, hCalendar, hReview, hRecipe, hProduct, rel-author (and indirectly rel-me)
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
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.
