## Progress and discussion

## Dual Readout with small data model extension
* Migrate to `RawTimeSeries` after CEPC DriftChamber PR is merged

## Framework `PodioOutput` writes broken files when dropping collections
* https://github.com/key4hep/k4FWCore/issues/95
* Definitely solved with `Frame` based I/O, soon enough?
* Check `PodioOutput` if it can be made to write "proper" files. (Juraj will take a look)

## `ddsim` stores its output in `Frames` now (DD4hep >= 1.24)
* https://github.com/AIDASoft/DD4hep/pull/1041
* [ ] Need updates to k4FWCore to be able to read these files
   * Need to identify the Gaudi interface to fulfill
   * See https://github.com/key4hep/k4FWCore/issues/94
   * Need to divide work. Will discuss offline (Benedikt, Thomas)
