This document was published by the Media Working Group as an Editor’s Draft.
This document is intended to become a W3C Recommendation.
Publication as an Editor’s Draft does not imply endorsement by W3C and its Members.
Each metadata entry must be defined by a W3C specification that has
reached consensus in the originating Working Group.
The specification defining each metadata entry must provide clearly defined
semantics. In particular, interactions with the media processing pipeline
(encoders, decoders, renderers, etc.) should be well defined.
A candidate registration entry must be announced by filing an issue in the
WebCodecs GitHub issue tracker so they can be discussed and evaluated for
compliance before being added to the registry. If the Media Working Group
reaches consensus to accept the candidate, a pull request should be drafted
(either by editors or by the party requesting the candidate registration)
to register the candidate. The registry editors will review and merge the
Existing entries may be changed after being published, through the same
process as candidate entries. Possible changes include modification of
the link to the public specification.
Existing entries may be deprecated. This requires Media Working Group
consensus, and if still active, consensus of the Working Group that
originated the registration entry specification.
