Hi Lorenzo,

Thank you for taking the time to put together this important discussion
paper.   I second the motion you made in the email:

Motion: The CF-netCDF SWG approves release of 11-163 “NetCDF Uncertainty
Conventions (NetCDF-U) 1.0” as an OGC Discussion Paper.

So it is now open for discussion among the SWG.   Hopefully we can complete
the discussion and the vote  by the end of the SWG session on next
Wednesday at the Austin TC meeting.

-- Ben
