3 Round table: config

Speakers: Alessandro Thea (STFC Rutherford Appleton Laboratory), Giovanna Lehmann (CERN), Gordon Crone (University College London), Henry Wallace (Royal Holloway, University of London), John Freeman (Fermi National Accelerator Laboratory), Marco Roda (University of Liverpool)

Marco

• Initial repository for the database is ready and tested. Marco tested the v5.2.1 version, while Shyam tested the develop branch. Note that the operation repository is only populated with the v5.2.1 set of configuration, so Shyam could only test the base repository. 
• Since the repositories are ready, it should be advertised again that the ehn1-config repo should not be used any more for NP02 development. People requiring access to the np02-config-base and np02-config-operation should require access to Marco or Wes. 
• Opening the respositories means that we need to send around the document that describe the logic of the implementation. We should do it ASAP. I also added a small paragraph related to the calibration workflow to clarify a doubt that came out with Wes last week. People involved in the review of the document should really make an effort to either approve or point out the issues.
• Work on the scripts to manage the repositories is in progress using another gitlab repo: config-management.

Gordon

• Trigger schema upgrade with trigger menu
• Added a functionality on the schema-editor to see which schema classes are tied to which schema files
• Made use of inheritance work from Alessandro to redefine ResourceSets for Detectors. Now able to declare the behaviour of `contains`.

Speakers: Alessandro Thea (STFC Rutherford Appleton Laboratory), Bonnie King (FNAL), Jonathan Hancock (University of Birmingham), Patrick Riehecky (Fermilab), Pierre Lasorak (Imperial College London), Tiago Alves (Imperial College London), Tiago Alves (Imperial College London)

Pat

• Outage last week, took too long to start again due to certificates. They need to be renewed every year.
• Any way to fix that?
  • Continue updating Kubernetes and certificates should sort themselves.
