Logical Compatibility identifies whether two or more logical elements work together without loss of meaning, structure, traceability, governance, or evidence expectations.
Logical Compatibility applies to Logical Nodes, Logical Communication Endpoints, Logical Data Structure Definitions, Logical Data Structure Instances, Logical Runtime Planes, Logical Interaction Patterns, and Logical Policy Constraints.
Logical Compatibility supports distributed operation. A producing Logical Node and a consuming Logical Node require compatible expectations about endpoint purpose, information structure, semantic meaning, version context, interaction pattern, and Runtime Plane participation.
Logical Compatibility does not require identical implementation technologies. Two implementation profiles use different technologies while preserving logical compatibility by maintaining the same logical definitions, interaction expectations, traceability, and governance constraints.
Condition in which logical elements work together without loss of meaning, structure, traceability, governance, or evidence expectations.
Specialization of Traceability, Governance and Authority, Data Structure Definition, and Communication Endpoint from Part 1, Sections 7.10, 9.6, 7.7, and 7.6; generalised from compatibility and versioning concerns in the original FX Demo Reference Architecture.
Logical Compatibility concerns the meaning and behavior of logical elements. It does not imply binary compatibility, protocol compatibility, wire-format compatibility, or deployment compatibility.
A Logical Node that publishes a validation-result event and a Logical Node that consumes that event remain logically compatible when both use the same logical endpoint purpose, information definition, version context, and Runtime Plane classification.
