Sylvia,

Your file validated the *RDF validator*. This means they were syntaxlly
correct. It does not mean they are valid against our Ontology.
Just like an XML file is well formed it does not mean it validates against
its DTD or schema. Please try to understand the difference here and our
goal: We must publish RDF files to the world that are conformant to our
Ontology.

Again here please read what the WG  requests. We never requested to cover
all of the metadata,as I have already explained to you. Furthermore we
said if you are missing properties, you should provide the HTML table with
the column 'RDF-tested' showing which properties you have used in your
example.

Hum, it seems you don't want to allow time to edit these two
tests cases.
Participation into a W3C WG is indeed time consumming. When you joined the
MAWG you commited to this statement " Effective participation to Media
Annotations Working Group is expected to consume one work day per week for
each participant; two days per week for editors."
see MAWG charter
http://www.w3.org/2008/01/media-annotations-wg.html

I am only trying to coordinate the work of this Group to have our specs
move forward to REC. I can not do anything if people don't want to work.
Please refer to the co chairs Daniel and Joakim (that I am copying here)
for the future of these formats in the Ontology spec.


Best,
