@arnoweiss wdyt?

Looks pretty complete to me. Might it make sense to think about automating this whole procedure?

[bs-jokri]

@arnoweiss automation is a good idea in any case. How would you envision an automation? Something like, if all MS1 checks are approved the status is automatically changend in a PR And the change is merged right away?

[arnoweiss]

Something a little different. This is the process that we want, right?

1. Model passes through sldt-semantic-models process.
2. Standardization in CX e.V. is started.
3. Standardization in CX e.V is achieved.
4. sldt-semantic-model updates status of aspect to "standardized"

As everything after step 1 is in someone else's responsibility, it'd be great if this repo could notice that step 3 is done and execute step 4 automatically.

Please note that model in a specific version ist standardized. So will this be a new line in the metadata.json extending the existing: { "status" : "release"}?

Yes, the status "standardize" will come after a model is in status "release"
