The UAF Resource Interaction Scenarios: Resources viewpoint is a UML Sequence diagram type that enables you to model Resources as a vertical object lifeline symbol, and Needlines as MessageFlow lines between the Resource lifelines. On this diagram you model the sequential order of Needlines, chronologically from top to bottom.

See Important tips on drawing Sequence-style diagrams for tips on moving the horizontal Message-style lines and moving the headers of the object lifelines to the top of the diagram.
