Project team round

Here we discuss topics that need broader attention, for example questions that came up but are outside a single project's scope, larger planned changes/PRs that affect all teams or pending work that is blocked by external factors.

1. Models / NESTML
   • STDP Dopa synapse now working in NESTML, reproduces the nest built-in version
   • some special cases of synapse models require deeper discussion about how/if to implement or delegate to different simulators
   • balance between scalable performance vs. complete flexibility in neuron and synapse model features
2. PyNEST
   • discussion/coding/PR for making pyNEST more independant of SLI
   • started to flatten the namespace hierarchy (esp. hl_api part), discussion and work ongoing, split to topic specific files
3. Kernel
   • nothing to report
4. Installation
   • long meeting discussing repository naming (issue)
   • minor issues being solved
5. Infrastructure
   • CI restructuring PR has one point of discussion still open
6. Documentation
   • redesign of webpage/documentation, planning satellite event for discussion (watch out for mail)
   • curation of list of publications is ongoing
7. EBRAINS
