Working with BESSER

BESSER is a model-driven platform: describe your domain as a model, then generators turn that model into running code. The model is the source of truth — when requirements change, update the model and regenerate. Never hand-edit generated code as your primary change.

Core workflow

1. Define requirements
2. Build a B-UML model (Python API, PlantUML, or web editor)
3. Validate the model: model.validate()
4. Pick a generator for your target platform
5. Generate code
6. Verify the output (run, test, inspect)
7. Iterate: update the model, regenerate
