### DIALS Office Hours

- ND talk to JBE about running
- Make informal promise for office hours, and a slack channel that people can make known that they have a request to chat/for help about a particular topic
- JBE booked room, not sent out invites/ zoom yet - try to get done in next week.
    - [ ] Consider sending reminder to slack day before advertising
- Graeme suggested "themes" for the office hours

### Metrics
- Aaron wants to have a dials tag attached to all export, then we can make sure that is always carried through to refined structure. Aaron will handle Phenix, DW will try for CCP4.
    - CCP4 GUI, data is lost when packaging mmcif
    - Ongoing investigations, optimism that can be fixed
- DGW made some progress, agreement to add history recording into experiments file. Will pick up again after Easter, but WIP.
- Discussion between Aaron/DGW about contents of history/approach across cctbx/dials
- Address when david back
- 08/05/25 update - DGW - PR nearly ready that records history item in experiments file. Top level field outside of experiment list. But will require a number of dials changes as often we make new lists/copies, so will need to copy across history. dxtbx PR first, then follow up with dials once in.At point of export, look through existing history items and extract integrate, scale lines and filter those out.
- Follow up with Aaron again next time.
- PRs and Blockers:
    - ~~https://github.com/dials/dials/issues/2931 - version numbering off~~
    - Aaron had build issue, a joint look has identified issues, DGW can continue
