<section id="purpose" typeof="bibo:Chapter" rel="bibo:Chapter" resource="#purpose">
<!--OddPage--><h2 id="h2_purpose" role="heading" aria-level="1"><span class="secno">1. </span>Purpose</h2>
<p>This registry is intended to enhance interoperability among implementations and users of
<code><a class="idlType" href="http://www.w3.org/TR/media-source/#idl-def-SourceBuffer">SourceBuffer</a></code> objects described in the
<a href="http://www.w3.org/TR/media-source/#">Media Source Extensions</a>(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.
</p></section>
<section id="organization" typeof="bibo:Chapter" rel="bibo:Chapter" resource="#organization">
<!--OddPage--><h2 id="h2_organization" role="heading" aria-level="1"><span class="secno">2. </span>Organization</h2>
<p>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 <code><a class="idlType" href="http://www.w3.org/TR/media-source/#idl-def-SourceBuffer">SourceBuffer</a></code> objects
created with the associated MIME-type/subtype pair.</p>
<p>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.</p>
</section>
<section id="entry-requirements" typeof="bibo:Chapter" rel="bibo:Chapter" resource="#entry-requirements">
<!--OddPage--><h2 id="h2_entry-requirements" role="heading" aria-level="1"><span class="secno">3. </span>Registration Entry Requirements</h2>
<ol>
<li>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.</li>
<li>Each entry must include a <var><a href="http://www.w3.org/TR/media-source/#sourcebuffer-generate-timestamps-flag">generate timestamps flag</a></var> value that must be used by
<code><a class="idlType" href="http://www.w3.org/TR/media-source/#idl-def-SourceBuffer">SourceBuffer</a></code> when handling the byte stream format.</li>
<li>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).</li>
<li>Each entry must comply with all requirements outlined in the <a href="http://www.w3.org/TR/media-source/#byte-stream-formats">byte stream formats section</a>
of the <a href="http://www.w3.org/TR/media-source/#">Media Source Extensions</a> specification.</li>
<li>Candidate entries must be announced on <a href="public-html-media@w3.org">public-html-media@w3.org</a>(<a href="public-html-media-request@w3.org">subscribe</a>,
<a href="http://lists.w3.org/Archives/Public/public-html-media/">archives</a>) so they can be discussed and evaluated for compliance before being added to the
registry.</li>
</ol>
<p>If a registration fails to satisfy a mandatory requirement specified above, then it may be removed from the registry (without prejudice).
