QVT12 — Figure 7.3

  • Key: QVT12-5
  • Legacy Issue Number: 15424
  • Status: closed  
  • Source: Institute for Defense Analyses ( Steven Wartik)
  • Summary:

    I am confused by something in the MOF QVT specification (version 1.1) and am not sure if it’s an error or my own misunderstanding. Figure 7.3 (p. 24) has links from two instances of ObjectTemplateExp to a single instance of PropertyTemplateItem (the one in the middle). Figure 7.6 (p. 30) shows a composite association between ObjectTemplateExp and PropertyTemplateItem. Why then are there two links to the instance in Figure 7.3? Doesn’t a composite association mean that a PropertyTemplateItem can be owned by only one ObjectTemplateExp?

  • Disposition Summary:

    The problem is that UML Object diagrams omit the decorations from instantiated relationships. Shrt of
    moving to a non-standard UMLX diagram, we can perhaps get away with some explanations.
