James, We need to wrap up this issue in order to allow the MAWG to move forward the Media Ontology spec. Could you please respond to this email and say: 1- that you cancel your initial formal objection. 2- that you agree to the MAWG proposal, that we don't plan to introduce quality parameter as we want to keep a simple list of technical properties.
