Daniel,

I had already anticipated the errata issue ;-)
I had added a link in the Ontology REc.
http://www.w3.org/TR/2012/REC-mediaont-10-20120209/

it says
"Please refer to the errata for this document, which may include some 
normative corrections."

Per W3C process, W3C Recommendations are frozen. It is impossible to 
change the document when published, except to republish a new version of 
the Rec.

Something we could do in 6 months or a year, including all the errata 
and adding the new mapping tables schemaorg and YouTube.

I have also discussed the Recommendation maintenance with my domain 
Leader, Philippe Le Hégaret. We agreed that the MAWG will be granted a 
one year charter extension to maintain these two specs, but no new 
deliverables.


Best,

Thierry
