2.11Opening remarks

Activities on the opening cross-checking day of the meeting 1300 Tuesday 10 April (chaired by GJS and JRO) were as follows.

• 
  The meeting logistics, agenda, working practices, policies, and document allocation were reviewed.
  
• 
  The results of the previous meeting were reviewed.
  
• 
  The primary goal of the meeting was to review the results of CEs, and identify promising technology directions, and potential adoptions to the draft and VTM.
  
• 
  Due to high number of inputs, parallelization and breakout work will be needed
  
• 
  Principles of standards development were discussed.
