Dear James,

The Media Annotations Working Group has reviewed the comments you sent 
[1] on the Last Call Working Draft [2] of the Ontlology for Media 
Resource 1.0 published on 08 June 2010.
Thank you for having taken the time to review the document and to send

The Working Group's response to your comment is included below.
Please review it carefully and *let us know by email at 
public-media-annotation@w3.org if you agree with it* or not
before deadline date [09-oct-2010].
In case of disagreement, you are requested to provide a specific 
solution for or a path to a consensus with the Working Group.
If such a consensus cannot be achieved, you will be given the

MAWG Resolution:
-----------------
The mapping tables included in the Ontology specification are 
established from the Media Ontology's core properties to various 
multimedia metadata formats. This list of formats is not closed, nor 
does it pretend to be exhaustive. A future version of this specification 
MAY include additional mappings if a need or use case is established for 
these new mappings.

You will read this statement in the Ontology specification.
http://www.w3.org/TR/2010/WD-mediaont-10-20100608/#mapping-table

To focus on your request to include VP8 and speex in our Ontology, the 
mapping tables are intended for multimedia *metadata formats*.

- VP8 is an open video compression format (codec).
- Speex is a free audio codec for Free Speech.

These are not *metadata formats*, and therefore not meant to be listed 
in our mapping tables.

The working Group is open to addition of more metadata formats. If there 
are particular metadata formats that you would like to see included in 
this specification, please bring your expertise to the working group and 
we invite you to join the Media Annotations Working Group.

We have also discussed the WebM issue. The Group has agreed to include a 
section for additional mappings to various media container formats, 
likely (3GP, FLV/Flash, MPEG4(MP4),MOV (Quicktime), OGG, WebM)

Please bring your expertise to the working group to fill the following 
mapping table for WebM.
http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/CR/test.php?table=containerWebM

It will then be included in the next publication of the Spec.
