MOF14 — Modeling OCL Helper Functions

  • Key: MOF14-21
  • Legacy Issue Number: 4569
  • Status: open  
  • Source: Adaptive ( Mr. Pete Rivett)
  • Summary:

    Many metamodels including the MOF Model (see 3.9.6) have 'OCL Helper' operations which are purely for the purpose of factoring the OCL constraints, and are not intended to be part of the 'external' model (e.g. to be represented in IDL).

    There seems to be no way of representing these in the MOF Model: and indeed the OCL Helper functions in MOF Specification do not appear in the XMI file, making it somewhat incomplete as a normative definition and meaning that many of the OCL constraints could not be executed by an OCL engine.

    This applies not only to MOF but to other metamodels.
