metaformats

metaformats is an extension to the microformats2-parsing specification for parsing invisible data published in HTML meta tags, both with an explicit methodology, and for backward compatibility with existing vocabularies that have multiple testable interoperable implementations.

This is a Living Specification that is subject to change as research discovers meta tag vocabularies in wide use and consumed by multiple implementations. Additional implementations are not encouraged at this time. This specification has no stable portions. Features are untested, unless explicitly labeled stable, draft, or proposed, or in stable, draft, or proposed sections. All features are likely to change substantively. While stable features are unexpected, it is a living specification and may eventually document some. When stable features are documented, substantive changes may be proposed by issues and errata filed in response to implementation experience, requiring consensus among participating implementers as part of an explicit to be defined change control process.
