Figure 3
A legend at the bottom identifies three types of boxes: A solid-outline box reads “Same as U M L 2”. A solid-outline highlighted box reads “Modified from U M L 2”. A dashed-outline box reads “New diagram type”. At the top center, a box reads “S y s M L Diagram (Same as U M L 2)”. Below it, three boxes are arranged horizontally and connected upward to “S y s M L Diagram”. The left box reads “Behavior Diagram (Same as U M L 2)”. The dashed center box reads “Requirement Diagram (New diagram type)”. The right box reads “Structure Diagram (Same as U M L 2)”. Under “Behavior Diagram”, four boxes are arranged horizontally and connected upward to it. These boxes read: “Activity Diagram (Modified from U M L 2)”, “Sequence Diagram (Same as U M L 2)”, “State Machine Diagram (Same as U M L 2)”, and “Use Case Diagram (Same as U M L 2)”. Under “Structure Diagram”, three boxes are arranged horizontally and connected upward. These boxes read: “Block Definition Diagram (Modified from U M L 2)”, “Internal Block Diagram (Modified from U M L 2)”, and “Package Diagram (Same as U M L 2)”. Below “Internal Block Diagram”, a dashed-outline box is connected with an upward arrow. This box reads “Parametric Diagram (New diagram type)”.SysML model composition diagram. Source: Wolny et al.
