UML14 — Metamodel and semantics for aggregations

  • Key: UML14-934
  • Legacy Issue Number: 2279
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: The metamodel and semantics for aggregations is still causing me
    much concern. Primarily, it is stated that black diamond (composition)
    must have linked lifetimes and dependencies between part and whole.
    This means that the parts are NOT separable from the whole. It also states
    that whilst there is only one owner that owner may be changed. This means
    that the parts MUST BE separable from the whole. This is a contradiction.
