3. ICG-WIGOS Task Team on WIGOS Metadata 4 th session  It was proposed to use the CBS “simple/fast track” procedure, for the approval of new or revised code tables in 2016. Draft tables can be used in "pre-operational mode“, meaning that they are considered to be “good enough” for practical purposes, while the formal approval process proceeds;  Expected small impact of not having formal approval, since changes during the approval process are expected to be limited to adjustments of the wording of definitions or to addition of new entries. It is proposed to go through the next approval “fast track” starting in June 2016.  Taking into account the conclusions and the tasks that need to be completed before the entry into force (July 2016) of the WIGOS Regulatory Material, the session agreed on the updates to the work plan.
