This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
The working group maintains a list of all bug reports that the editors have not yet tried to address; there may also be open bugs in the previous bug tracker.
Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification before it eventually reaches the Candidate Recommendation stage should join the mailing list mentioned below and take part in the discussions.

This document was produced by
a group
operating under the
5 February 2004 W3C Patent
Policy.
W3C maintains a public list of any patent
disclosures
made in connection with the deliverables of
the group; that page also includes
instructions for disclosing a patent. An individual who has actual knowledge of a patent
which the individual believes contains
Essential
Claim(s) must disclose the information in accordance with
section
6 of the W3C Patent Policy.

1. Purpose
This registry is intended to enhance interoperability among implementations and users of
SourceBuffer objects described in the
Media Source Extensions(MSE) specification. In particular, this registry provides the means (1) to identify
and avoid MIME-type collisions among byte stream formats, and (2) to disclose information about byte stream formats accepted by MSE
implementations to promote interoperability.
2. Organization
The registry maintains a mapping between MIME-type/subtype pairs and byte stream format specifications. The byte stream format specifications describe the
structure and semantics of byte streams accepted by SourceBuffer objects
created with the associated MIME-type/subtype pair.
This registry is not intended to include any information on whether a byte stream format is encumbered by intellectual property claims. Implementors and users
are advised to seek appropriate legal counsel in this matter if they intend to implement or use a specific byte stream format.
3. Registration Entry Requirements
- Each entry MUST include a unique MIME-type/subtype pair. If the byte stream format is derived-from an existing file format, then it SHOULD use the
MIME-type/subtype pairs typically used for the file format.
- Each entry MUST include a generate timestamps flag value that MUST be used by
SourceBuffer when handling the byte stream format.
- Each entry MUST include a link that references a publically available specification. It is recommended that such a specification be made available
without cost (other than reasonable shipping and handling if not available by online means).
- Each entry MUST comply with all requirements outlined in the byte stream formats section
of the Media Source Extensions specification.
- Candidate entries MUST be announced on public-html-media@w3.org(subscribe,
archives) so they can be discussed and evaluated for compliance before being added to the
registry.
If a registration fails to satisfy a mandatory requirement specified above, then it MAY be removed from the registry (without prejudice).
