# Agenda

## 1. Review previous minutes and assign a note taker

- [X] Minutes approved

Open Actions from previous meetings:

- [ ] ACTION2: CK to discuss with MS and contact a X-ray manufacturer
- [ ] ACTION_FEB4: BMM organize meeting between AM, BMM, JS, BBM & Daphne to start discussion w.r.t. IUCr & CIF format
- [X] ACTION_FEB5: JS Invite Arie van der Lee to meet us
- update: given up trying to contact after lack of feedback
- [ ] ACTION_APR4: JS and BBM to decide on formalization of lookup paths for e.g. wavelength, incident angle (whether it is in column or header).
- [X] ACTION_APR7: AN to chase SNS-ORNL w.r.t. round-robin sample
- update: contacted Mathieu Doucet. Ready to leave SNS. Suggestion to go back around facilities. Need FRM-II and most of ISIS & PSI. Will suggest send to ISIS for remeasurement before moving on to FRM-II
- Biggest issue is the turn-around time at each facility.
- [ ] ACTION_APR8: ARM to look into mailing list options.
- update: waiting on ISA to pay

## 2. Reports from each working group

### Education & Outreach

* AGM: Videos & slides available.
* SXNS: Meeting for orso after SXNS17 in July 2024 at ILL/ESRF. Philipp Gutfreund will join the next chair's meeting to discuss details.
* Constitution: New version written in less legalistic style. Review in progress.
* Webpage needs fixing, incl. SLD webpage. SLD server needs resolving ASAP. ARM is working on web page when possible.

### Data Formats

- [ ] ACTION_JUL31 "NeXUS v1", code to write out ORSO files into an HDF file. Can we merge https://github.com/reflectivity/orsopy/pull/108 (and https://github.com/reflectivity/orsopy/pull/107?). This will involve some back incompatibility with already released orsopy. We decided that downstream breakage probably wouldn't be all that bad. AN thinks that BBM and AG would need to be involved in a discussion to merge these.

### Reproducibility

- CK discussed with David Cortie about samples
- Standards box work
- Replacement for CK?
- Someone from XMAS beamline
- Someone from Frank Schriber's group

### Data Analysis

- Frank Schrieber's group will create a page on machine learning for the website.
