UMLR — Making the default for Generalization isDisjoint=False is contrary to modelers' expectations.

Open Closed All
  • Key: UMLR-395
  • Status: open  
  • Source: Change Vision ( Michael Chonoles)
  • Summary:

    Almost all UML modelers assume that default semantics for Generalization is isDisjoint=True. The justification for making the isDisjoint=False (overlapping) the default escapes me.

    Most real-world semantics are disjoint, and I believe most programming languages are also disjoint.

    Please change the default for isDisjoint=True
