====== Command Producer Role ====== [[dido:99_annexes:annex-b-terms-and-definitions:c:start|Return to C Terms]] ===== Discussion ===== A Command Producer Role identifies a Logical Node's responsibility for issuing a command through a Logical Communication Endpoint. Commands express intended operational action. They belong primarily to the Logical Control Plane unless a domain profile defines a more specific logical treatment. A command differs from a domain event because it instructs a participant to act rather than reporting that something occurred. A Logical Node performing a Command Producer Role identifies the command, the target Logical Node or role, the expected acknowledgement, the applicable Runtime Plane, and the traceability expectations. ===== Definition ===== //Communication Role responsible for issuing a command through a Logical Communication Endpoint.// ===== Source ===== Specialization of Communication Endpoint, Node Role, and Control Plane from Part 1, Sections 7.6, 7.4, and 8.2; generalised from control-plane command material in the original FX Demo Reference Architecture. ===== Note ===== A Command Producer Role does not require a specific command protocol, middleware feature, orchestration command, or API style. ===== Example ===== A logical Control Node performs a Command Producer Role when it issues a request for another Logical Node to report status, pause work, resume work, retry processing, or initiate recovery. ---- [[dido:99_annexes:annex-b-terms-and-definitions:c:start|Return to Top]]
