Semantic Message Flow Diagram

A diagram that unifies the direction of control and the direction of data into a single connection line, visualizing the semantic information flow among processes, entities, and events. Each connection line (message flow) simultaneously represents the trigger for an action (control) and the transmission of information (data), expressing the semantic causal structure of actions, information, and state transitions.

In SimpleModeling.org articles, the abbreviated term “Message Flow Diagram” is primarily used.

While BPMN Message Flow represents communication between different processes, the Semantic Message Flow Diagram handles the integrated semantic structure of control and data within a single model.
