UML22 — UML 2 Super / Kernel / excessive restriction on redefinition

Open Closed All
  • Key: UML22-854
  • Legacy Issue Number: 8461
  • Status: closed  
  • Source: International Business Machines ( Mr. Jim Amsden)
  • Summary:

    In section 7.3.44 on pg. 130 of ptc/04-10-02 there is a constraint that states: “All redefinitions shall be made explicit with the use of a

    {redefines <x>}

    property string.” Unfortunately, this is violated in numerous places in the metamodel. This results in numerous inconsistencies in the metamodel.

    Recommendation:

    As a practical resolution with minimal impact, it is recommended that this restriction be removed. This means that the use of the same association end name for a given association end implies a redefinition of the corresponding association end in an ancestor class.
