To convert CRC responsibilities into a typed domain model, you map Class-Responsibility-Collaborator cards into explicit properties, operations, and relationships. This generates a structured domain-model.md defining object knowledge, method signatures, and composition boundaries.

Defining object properties and operations from domain-driven design involves extracting what each object must know to fulfill its responsibility. You specify methods with parameter and return types, aligning operations directly to invariants from your business logic.

Modeling class relationships and cardinalities across OOAD modules requires defining composition and association boundaries. You transform collaboration data into a typed domain surface with clear cardinalities to validate interactions across distinct classes.

Generating a domain model for explicit properties and methods requires four specific inputs: crc.md, business-logic.md, domain-walkthrough.md, and object-sketch.md. These files provide the responsibilities and invariants needed to produce the final output.

Yes, you can use object sketches and business logic to drive class design. The domain model generator consumes object-sketch.md and business-logic.md alongside CRC inputs to produce a fully typed domain-model.md for your architecture.

Your domain model needs typed properties and composition boundaries to enable precise modeling and validation. Structuring associations with clear cardinalities ensures object interactions remain consistent with invariants across all modules and classes.
