OK, sounds a good topic for tomorrow.  I'd like to keep the conversation
going.  I'll make an announcement shortly.

Hi all,

we might this discuss this QC aspects at the telco tomorrow. The most
recent version of WC definition which is available to me is from April
this year (see PDF attachment). Here QC-L1 contains both, CMOR-2
compliance and CIM metadata documet availability. But this incudes the
METAFOR timeline form April with CIM questionnaire availability in July
2010. This has now postponed to September and we should review and
finalise the April 1020 status. Along this line we have the discussion
about access constraints as preparation for the security telco the week
afterwards.

Would this be ok as topics for tomorrow's telco?

Best wishes, Michael
