EAI — Unnamed derived association between an EAITerminal and a source or sink

  • Key: EAI-16
  • Legacy Issue Number: 4869
  • Status: closed  
  • Source: Model Driven Solutions ( Ed Seidewitz)
  • Summary:

    Document: UML Profile and Interchange Models for EAI
    Section: 6.3.3 (EAITerminal)

    Description:
    The last constraint in this section states that "An EAITerminal on the exterior of a node constructed from an FCMComposition has a derived association with a single source or sink." Since it is not named, it is unclear to what "derived association" this statement refers, if the association even exists in the metamodel.

    Recommendation:
    The constraint needs to be made explicit. Perhaps the "interface" association from FCMNode to FCMTerminal (which is a derived association in Figure 6-2) is meant. In this case, however, note that the constraint cannot be written as a constraint on FCMTerminal, since this association is not navigable from FCMTerminal back to FCMNode. I think the constraint would have to be on FCMComposition (or, better, on EAIMessageFlow).
