Hello,

A consensus seems to be taking shape about the model evolution for pixelated data:
  + Adding several fields to provide the dimensionality in each domain.  (s_dim, em_dim, etc) as described in the draft
  + These are added as 'required' fields.. so must be populated for all records
  + These fields provide for instance the size of each image axis.

These new fields can however not be used to provide a robust representation the dimension of non pixelated data (e.g. number of 
event in an event list)

The proposal to complete the version would be:
  1) To keep the new *dim* fields
  2) To support the EventList and other non pixelated as product_type
  3) To clearly specify that the *dim* columns must be set with NaN for non pixelated data.
  4) To provide some use cases about discovering non pixelated data with ObsTap

That would quiclky allow us to start the RFC period for ObsCore without having to wait on a agreement about how to model non 
pixelated data
