Return to Requirements

Each FX logical Node SHALL identify its FX logical Node Roles, responsibilities, Runtime Plane participation, Communication Endpoints, information structures, governance constraints, traceability relationships, and evidence expectations.

Part 3, Section 17.3: FX Logical Node Requirements.

Each FX logical Node must be defined with sufficient architectural detail to support consistent interpretation, implementation, governance, and verification. Identifying the Node Roles, responsibilities, Runtime Plane participation, Communication Endpoints, information structures, governance constraints, traceability relationships, and evidence expectations provides a complete architectural specification for each logical Node while remaining independent of implementation technologies.

A consistent definition of these architectural characteristics enables logical Nodes to be reviewed, governed, traced, and specialized without ambiguity and provides the foundation for subsequent Implementation Profiles and deployment models.

This requirement applies to every FX logical Node defined by the FX Demo Logical Profile.

It applies specifically to:

• logical Node specifications;
• FX logical Node Roles;
• logical responsibilities;
• Runtime Plane participation;
• Communication Endpoint definitions;
• logical information structures;
• governance constraints;
• traceability relationships; and
• evidence expectations.

Verification SHALL confirm that each FX logical Node identifies the required architectural characteristics.

Verification activities should include review checks confirming that:

• one or more logical Node Roles are identified;
• logical responsibilities are documented;
• Runtime Plane participation is identified;
• Communication Endpoints are defined;
• logical information structures are identified;
• governance constraints are documented;
• traceability relationships are defined; and
• evidence expectations are specified.

This requirement supports the complete architectural specification of each FX logical Node within the FX Demo Logical Profile and provides the information required for governance, traceability, implementation planning, and evidence generation.
