Return to Requirements

Logical Node Collaboration SHALL identify explicit logical cooperation among Logical Nodes through Communication Endpoints and interaction patterns.

Part 2, Section 16.3: Logical Node Requirements.

Logical Node Collaboration defines how Logical Nodes cooperate without introducing hidden dependencies or implementation-specific relationships. Explicit collaboration improves interoperability, reviewability, governance, and traceability.

This requirement applies to Logical Node collaboration throughout the Logical Architecture.

It applies specifically to:

• Logical Nodes;
• Logical Communication Endpoints;
• Interaction Patterns; and
• Domain Logical Profiles.

Verification SHALL confirm that Logical Node Collaboration identifies explicit cooperation among Logical Nodes.

Verification activities should include review checks confirming that:

• collaborations are explicitly identified;
• Logical Nodes cooperate through Communication Endpoints;
• interaction patterns describe the collaboration; and
• hidden dependencies are avoided.

This requirement supports traceability between collaborating Logical Nodes, Communication Endpoints, and Logical Interaction Patterns.
