Party & Location models  Nigel
  • Nigel: oimt2020.ND.003-ConsideringPartyAndLocation.pptx (discussed and addressed)
  • Kam:
  • Xiaobing: TR-512.14_OnfCoreIm-Location-xbn-review.docx
    • Comment: Should reflect class hierarchy in the Qualified Name.
      • Nigel: To consider. Will need to update the GenDoc 
    • Comment: Should indicate the unit of the Carttesian attributes (x, y, z) and the precision to the orientation attributes (theta, pi, psi).
      • Nigel: These are example structures. No intention to standardize these.
  • Kam:
    • Comment: According to the UML modeling guideline (, the spec class is an abstract class. That is, no instances of the abstract class will be created. In this Party and Location models, it is not so (e.g, see the instance diagrams in Figures 4-3, 4-5 and the Location model). 
      • Nigel: In the Party and Location models, the spec classes are not for augmentation. They are concrete classes for specifying properties that are invariant with respect to the instances of the base class.
        • Will continue discussion off-line after the call.
    • Comment: In Figure 4.-3, cd1:ConstraintDomain contains lr1:LocationRole and lr2:LocatonRole, both have the same local ID value localId-1.
      • Nigel: In the diagram, the relationship between ConstrainDomain and LocationRole is not containment relationship.
      • The diagram needs update.
