      Description

      The Lossy Compression Working Group's work (DM-11819, DMTN-068) suggests that it may be realistic and useful to maintain an on-disk archive of at least one data release's PVIs for all visits, together with the AP-derived PVIs for more recent data that's not been through a data release yet.

      We now need a cost and design impact study for doing this, in order to be ready to process DM- and Project-level change requests to add this to the baseline.

      This should be considered together with DM-11880, the request to clarify whether we have already added resources for the storage of all raw image data on disk to the project baseline.
