Specific proposal
- Adopt common mDST, including “fat” data from new subsystems
- implementation “volunteers”: Frank & Mike
- In production, create
- event.root files, “all” of which migrate quickly to HPSS
- common mDST, which remain disk-resident in production area (freeing space on PWG disks)
- in principle could also create special mDSTs for RICH, TOFp, EMC
- ~10% “extra charge”
- subsystems should act “responsibly” towards common mDST (migrate improvements)
- common mDST must be re-generable from event.root files
- proper Maker taking StEvent as input
- can fix small calib etc. issues without full reproduction
