Re: Response to your LC Comment -2393 on Media Ontology spec

Dear Thierry,

I most certainly do not cancel my objection.

Please send me the names and email addresses of all persons who

metadata.

I have asked the VP8 and Speex media authorities to complete your
ontology forms.

Sincerely,
James Salsman
