 +
 +===== Discussion =====
 +
 +A conceptual model describes the relevant concepts in a problem domain and the relationships among those concepts.
 +
 +Within the FX Demo Reference Architecture, a conceptual model establishes shared meaning before logical modeling, platform-specific modeling, or implementation work begins. It identifies domain concepts, policy concepts, governance concepts, information concepts, roles, relationships, constraints, assumptions, and boundaries.
 +
 +A conceptual model supports agreement about meaning. It does not define implementation artifacts, platform features, software structures, database structures, middleware structures, deployment structures, or runtime components.

 +
 +===== Note =====
 +
 +A conceptual model defines domain-level meaning and scope.
 +
 +A conceptual model precedes Logical Models, Platform-Independent Models, Platform-Specific Models, and implementation artifacts in the architectural refinement chain.
 +
 +Conceptual models organize domain meaning. Logical models organize architectural concerns. Platform-specific models organize selected technology realisations of those concerns.
 +
 +===== Example =====
 +
 +A conceptual model identifies jurisdiction, sovereignty, residency, governed release, release evidence, reporting party, receiving authority, policy authority, and policy decision as domain concepts.
 +
 +A logical model organizes those concepts into architectural viewpoints such as policy control, information exchange, evidence, audit, and governance.
