UML2.1.2: 17.2.1 InformationFlow (from InformationFlows):
'Information flows require some kind of “information channel” for transmitting information items from the source to the destination. An information channel is represented in various ways depending on the nature of its sources and targets. It may be represented by connectors, links, associations, or even dependencies. For example, if the source and destination are parts in some composite structure such as a collaboration, then the information channel is likely to be represented by a connector between them. Or, if the source and target are objects (which are a kind of InstanceSpecification), they may be represented by a link that joins the two, and so on.'
In MagicDraw UML:
- use a Connector, Association, or Dependency to carry an InformationFlow.
- (A Link is not supported as an information flow channel.)
