# Agenda

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

- [ ] ACTION (everyone) to update what happened at the Grenoble workshop on the webpage (https://www.reflectometry.org/workshops/workshop_2024/), make past tense and add conclusions.
- [ ] ACTION (JC) Upload photos to github.
- [ ] ACTION TA & JC to update the survey & distribute
- [x] ACTION AN to ask Wojtek how to sign Windows executables.
- [ ] Update on OSCAR call for grants w.r.t FAIR data. https://oscars-project.eu/open-calls.

### Updates

- MS has some notes, but not clear where to add them. (Add them to --> https://github.com/reflectivity/reflectivity.github.io/blob/master/workshops/workshop_2024/index.md)
- TA recommends that a meeting report is not necessary, but workshop page to should be modified to be in past tense with conclusions.
- TA and JC have updated the survey and it has been sent out.
- No follow up cause not enough content.
- Tim Snow did not want the fact that ISA can sign software on the website (but can be communicated via a news email).
- AN Signing process involves Tim generating a certificate and getting added to a developer organisation.
- AN Piotr Rozyczko can help for Windows signing but ESS paid for Sasview Windows signing certificate
- ARM The two methods for code signing (apple vs windows) are complex and different, software is awful, long live the command line.
- MS Mantid developers might be able to advise on how to do it.
- MJ ESRF cannot participate in OSCAR call, they got money the last call so are barred (more than 250 k EUR)
- There is a plan to submit a proposal for reciprocal space remapping (not lead by ESRF, lead by Francesco Carla @ Diamond) but maybe ORSO should get involved (data formats?).
- Try to stay aware of their work so that overlaps are leveraged as well as possible.
- Philip Mousley at Diamond might be involved so can ask him also.
- Should we try and get a ORSOpy developer for a few years? (ARM)
- Need to check eligable facilities (https://oscars-project.eu/projects), ones with less then 250 k EUR existing.

## 2. AGM at SXNS.

### Planning

Online?
- Remote seems like a good idea.
- AN worth catching up at ICNS?
- Could we have a code camp (physical location)?
- This would be a nice idea for ORSOpy which is quite slow on the development cycle.
- When Sasview do this, facilities pay
- A bit of a half-baked idea (TA), someone else's problem if they wanna do it

## 3. Reports from working groups

### Analysis WG

- AN Updates to the workshop pages is complete.
- Wider development group for Refl1D -- code camp with ISIS and ORNL people (@ ORNL).
- Lots of different perspectives.
- Trying to make a full release with new web interface. Too many cooks makes the soup take longer to prepare...
- Some ISIS effort to add nested sampling to Refl1D

### EnO WG

- TA meeting with Stefan occasionally.
- ORSO could be a good opportunity for feedback for ISIS user committee.
- TA collating information from the user committee's via Slack.
- Share information about the existence of these committees.
- See above about the lack of newsletter.

### Reproducibility WG

- No updates. Maciej Jankowski and I (ARM) need to set up a standing meeting.
- ARM takes blame for this, or rather blames University of Bristol.
- MJ is developing a package to improve data reduction/cleaning of data.
- Might be of interest (https://joss.theoj.org/papers/10.21105/joss.04397), probably a lot simpler than what ID10 is implementing.
- This project is somehow links to EOSC-something.
- Does this write .ort files?
- Bruker might **look at** adding .ort writing cause ESS is buying an instrument from them. Money talks.

### Data formats WG

- MS and JC met earlier this week.
- Next steps: .ort format is reasonably complete.
- Can we push the implementation of the simple ASCII model definition?
- This will require an automated way to describe samples.
- For interest: this was the thing that JC and ARM were talking about (https://github.com/reflectivity/orsopy/pull/132#discussion_r1838369597)
- How do Refl1D and refnx handle the sample input from the ort file?
- ARM thinks that GenX is the only one that handles it.
- Refl1D definitely doesn't look at the units of the columns during import (BBM)
- https://github.com/reflectometry/refl1d/issues/226
- MS will only be giving out .ort files, .txt is dead, long live .ort!
- Old motofit cannot load an ort file. motofit is dead, long live refnx?
- Should ORSOpy have opinions on units?
- Unit conversions are hard!
- Should there be an internal to ORSOpy unit standard (ARM says no cause this adds additional complexity to ORSOpy)
- Correction: ORSOpy does depend on `pint` (sorry BBM).

### Sample environment WG

- SA and BH had a meeting about "How to get started!"
- Main aim is to have a list of available sample environments that are at the different facilities with some information about the sample enviroment.
- SA has started to build up a excel-style spreadsheet with information about solid-liquid flow cells and langmuir troughs.
- Should we have email details?
- No, link to facility webpage (i.e., if the sample environment is at Diamond I07, link to the I07 webpage)
- SA spoke with Andy Church to ask about what the ISIS Sample Environment are happy to share:
- Pictures, diagrams and photos
- For now the table is great!
- SA will write out a few examples written out and then crowdsource the work.
- Build towards a ORSO webpage with background on what a given sample environment is "i.e., what is a solid liquid cell".
- (ARM) can the background stuff be on the "learn" pages?
- (TA) adding stuff to the "learn" pages is not clear
- ARM will add some documentation links to the JupyterBook information
- BH the need for a sample environment library is needed cause problems between ILL and ISIS cause the ILL cryofurnace is better (according to a user).
- BH has contacted Jana from SwissNeutronics to get some blocks polished?
- This is a new option for block polishing. The "current mod" that the ILL use are not great.
- AN rates some Polish polishers (Polish polish).
- AN ANSTO has a sample environment book, but the soft matter samples environments are often a bit hacked together (NormSpecials). How do these get caught by the plan.
- The aim is to capture the more general designs and then cataloguing that the NormSpecials exist would be a good development.
