  • Summary:

    The class “IsPartOf” is an example of an instance in the standard where a class is used to represent a relationship where a simple UML association would do. The concept is that an Exhibit can be part of other Exhibits. This is most naturally expressed as an “isPartOf” association that has Exhibit as its source and target. Introducing a class for this relationship clutters the model.

  • Disposition: Resolved — SACM 1.0b2
  • Disposition Summary:

    This issue was raised during the review of the Evidence metamodel by Integrate.
    Reject - current situation is fact oriented (aligns with SBVR). The modeling style of the
    Evidence metamodel uses MOF in a disciplined way which facilitates a more straightforward mapping to
    RDF triples and to SBVR statements. In particular, the modeling style of the Evidence Metamodel
    introduces explicit "association classes" named with verbs or verb phrases when a relation between two
    entities is modeled. Shortcutting this pattern using "natural modeling style" breaks this pattern and makes
    RDF mapping more complicated.
    Disposition: Closed, no change
