CWM12 — Invalid explicit references for some 'association generalizations' in the

  • Key: CWM12-48
  • Legacy Issue Number: 5695
  • Status: open  
  • Source: Adaptive ( Mr. Pete Rivett)
  • Summary:

    This applies to CWM 1.1 (and also CWM 1.0).
    Sun MDR user Vincent Lombart spotted that he was getting the same
    association exported twice, which I tracked down to the following problem in
    the metamodel.

    There should be no explicit association between ClassifierMap and
    TransformationMap: the diagram in the CWM spec just documents the fact that
    the inherited ownedElement association is used to link these classes.
    The CWM XMI file is produced by the Unisys Rose integration which explicitly
    ignores such associations (signalled by '/' on the association ends - normal
    derived associations have '/' on the association name). This is used in
    several places e.g. in Relational model to show that Column and ColumnSet
    are linked using the owner-feature association.

    However in the ClassifierMap case there are also corresponding references
    explicitly defined as pseudo-attributes on Classifier and TransformationMap
    which has caused the references erroneously to be generated into the XMI

    On further investigation, the following inherited associations have
    superfluous references:

    XML:ElementType <-> XML:Schema
    XML:ElementType <-> XML:Attribute
    Transformation:TransformationMap <-> Transformation:ClasifierMap
    Transformation:TransformationActivity <-> TransformationStep (in this case
    the references are called 'step' and 'activity')
    BusinessNomenclature:Taxonomy <-> Concept
    BusinessNomenclature:Glossary <-> Term
    BusinessNomenclature:BusinessDomain <-> Taxonomy (in this case one
    reference is called just 'domain')

    Proposed resolution:
    Delete the above references/pseudo-attributes (with stereotype of
    <<reference>> though this is hidden on the diagram).
