UML14 — "Physical" Metamodel References (uml-rtf)

  • Key: UML14-964
  • Legacy Issue Number: 3124
  • Status: closed  
  • Source: Google ( Don Baisley)
  • Summary:

    UML's "physical" metamodels need to be more careful about which association
    ends have corresponding references. In places where an association end can
    relate one element to another element imported from another model, it is
    generally best to not have a reference on the inverse end. Note that
    "reference" is a MOF concept. The lack of a reference does not affect
    whether an association end is navigable. It does affect whether a link can
    be in a different MOF package extent (this is a MOF constraint). If both
    sides of an association have references, then related objects are forced to
    reside in the same package extent, which prevents the federation of UML

    An important aspect of interoperability comes from federation: UML
    facilities having links to other UML facilities. The overuse of references
    prevents use of such links in places where they should be allowed.
