BACM11 — Resolve specification of ownership and quantification in OWL specification

  • Key: BACM11-28
  • Status: open  
  • Source: Thematix Partners LLC ( Mr. James Rhyne)
  • Summary:

    In MOF metamodeling, OCL and other constraints apply to instances. In the BACM, these instances are also classes and inherit from their meta-classes (same for associations). In the translation to OWL, there is no instance/metaclass association and no mechanism (other than punning) that is useful. The instance model in OWL is created by specializing the BACM base model. E.g. VS is a specialization of ValueStream and VSS is a specialization of ValueStreamStage. But [VS owns VSS] must be stated for VSS to exist and [VS1 owns VSS] may not be stated for VS1 not equivalent to VS. This is a requirement on the ontology maintainer, not a requirement on the individuals that can be addressed by an OWL reasoner.
