UML24 — "isStatic" property of Feature no longer appears in any diagram

  • Key: UML24-79
  • Legacy Issue Number: 15429
  • Status: closed  
  • Source: Simula Research Laboratory ( Bran Selic)
  • Summary:

    I noticed that the "isStatic" property of Feature no longer appears in any diagram. There may be others missing meta-attributes, but this is the one I detected. I realize that the XMI is the definitive spec of the metamodel, but, nonetheless, I think that the diagrams should be complete and not partial. Diagrams are for human readers and XMI for machines (unless, of course, you are Pete Rivett – just kidding, Pete!).

    Also, I am disappointed that you retained the practically useless notion of navigability in the metamodel, even though we now have the dot notation supported in diagrams. Given the fact that navigability is a run-time concept, I see no value in keeping it in the metamodel, which is, after all, a static definition. (But, I am pretty sure I will now be deluged with people who will try to convince me that navigability arrows are still useful (my response: no, they are not).)

    Perhaps the "isStatic" problem can be fixed as an editorial fix prior to the meeting?

  • Disposition Summary:

    Show the isStatic property. In addition, this is a systematic error, and there are other cases where the metamodel has content that does not show on any diagram.
