# Agenda

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

- [ ] Minutes approved

Open Actions from previous meetings:

- [X] ACTION2: CK to discuss with MS and contact a X-ray manufacturer.
- MS's recollection was that CK asked the X-ray manufacturers, but they weren't really interested.
- [x] ACTION_FEB4: BMM organize meeting between AM, BMM, JS, BBM & Daphne to start discussion w.r.t. IUCr & CIF format
- Jochen is giving an ORSO talk next week @ a DAPHNE meeting.
- [x] 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).
- Decision was made, it's implemented in the NeXUS writer branch (PR 108?)
- [ ] ACTION_APR8: ARM to look into mailing list options.
- update last meeting: waiting on ISA to pay
- there's now a bit of money in ISA account from ESS. ISA would pay directly for that, but they're working out how to do that for SAS first (we'll follow)
(Nov24 follows)
- This is still an open question because there's not enough money to get everyone a hosted service for mailman3.
- ISA has a DNS.
- Wojtek, Tim, BBM are going to get Apple Developer Account, and a Microsoft Dev account to sign and notarise packages for installation.
- [x] 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?).
**PR108 has now been merged, hurray**
- AN would be more comfortable for BBM or ArturG to merge these.
- We're going to merge 108 first.
- BMM is going to send some files to BBM to check whether the files the beamline that she's using has all the correct metadata. Example NeXUS files are at https://www.reflectometry.org/projects/file_formats/examples/.
- [ ] ACTION_SEP25 Work out costs for AGM at SXNS and how we want to organise the meeting (everyone)
- [x] ACTION_SEP25 Invite Alexander Hinterhof (Tubingen), Stefan Kowarik (from Graz), Linus Pithan (DESY) to replace CK on Reproducibility working group (BMM)
- we asked, Stefan said he was interested, but hasn't taken us up on the offer so far...
- [ ] ACTION_NOV24 MS is going to ask Stefan Kowarik again to jog his memory.
- Stefan has just been elected as a committee member/representative for ESRF users organisation.

## 2. AGM at SXNS.

SXNS meeting will be on the ILL/ESRF campus, 15-18 July.
Cost of infrastructure is cheap. ILL is shutdown during the meeting, so the users aren't occupying ILL 'infrastructure' (accommo, auditoriums, etc). Meeting is limited to 150 people.
Thursday 18Jul (lunch) until Friday evening there is time for satellite events. There are already three satellite events in unofficial discussion [SAGA, Symposium in honour of John White (2 sessions)]. The ORSO meeting will probably be on the Friday. ORSO has no money to pay for a satellite meeting, so should there be a small amount added to the rego fee, or could we ask sponsors to help defray costs (food/drink)? In return they should be offered e.g. a stand/advertising/publicity, at different reward levels of Bronze/Silver/Gold. They should be asked sooner rather than later.
*Could we have an industrial session where they invite them to present (e.g. on their equipment), and at the same time engage them on the ORSO format?*
*Get them to sponsor specific sessions, such as a poster session*

We should probably have the ORSO satellite meeting in a hybrid mode, to enable a wider audience.
This'll be only the second in-person meeting.
sciency talks, code camp, carry on the discussion with the 'traditional' subjects (reproducibility, data format, analysis etc.). Should we propose new working groups?
Get someone from PaNOSC/EOSC to give a talk on what they developed?

- plenary session
- AGM
- sponsor talk
- lunch
- working groups in breakout rooms (4).
- sciency talks

## 3. Reports from each working group

### Education & Outreach

* Constitution:
- TA has distributed the constitution and got some comments back from a few people. The 'editors' present at this meeting provisionally accepted it (TA is going to check with Jos/Artur/Adrian Rennie).

* SLD database:
- Has to be migrated to an ISA server.

ACTION_NOV1: TA to book webpage editing session with JS

### Data Formats

- BMM reported on a PSE discussion of roles of users and facilities in open data. There were delegates from 31 countries from the synchrotron side and 12 from neutron facilities.
- ~~Facilities have GDPR responsibilities so are careful not to expose data to others.~~
- Facilities are also sensitive to data being accessed by others before the embargo period ends.
- MS reports the previous two points are holding back implementation of ORSO within Mantid at ISIS. These embargo periods are implemented by the facility data policies.
- PR108 (NeXUS writer) is merged, **hurray**.
- There's also an orsopy conda package now, available from conda-forge.

### Reproducibility

- CK is stepping down as co-chair. StefanK identified as an ideal successor, but needs to be queried again (get him to say yes).
- Samples returned to ISIS. Remeasured on INTER. (Remember it's a blind trial)

### Data Analysis

- orsopy conda-forge package and NeXUS .ORB writer.

Thanks Tom for chairing.
Happy Christmas everyone.
