Talk:Composite Redesign

Berk, I like the idea of eliminating vtkMultiGroupDataSet and I agree that it's confusing to assume first-level (or second-level in the case of vtkTemporalDataSet) sub-blocks are chunks of data from different compute nodes with ostensibly the same structure. I share your uncertainty about vtkMultiPieceDataSet... it seems like a lot of work. One alternative might be to use vtkInformation keys to mark blocks that share structure and provide some utility routines in the base class to help with ghost levels, etc.
