As far as I can see R34 corresponds to what I have and sent you earlier today. But the actual RDF and Turtle in the spec was probably generated by PA...

It would be better if he could clarify the situation as he probably know better about the genesis of these version as embedded in the spec (and why these differences have shown up)

I am happy to help but I don't want to add to the confusion.

Jean Pierre
Pierre Antoine,


Looking at the former RDF in the CR version
http://www.w3.org/TR/2011/CR-mediaont-10-20110707/#ont-owl

Looking at the current RDF in the RR version
http://www.w3.org/TR/2011/PR-mediaont-10-20111129/#ont-owl


both files have the same version number "R34 and same date "2011-04-06"
but the files are different.

Can you please make sure the PR version is the good one.

I would not want to mess the spec with these last minute updates.

Thierry
