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
