Overview

This page describes the SBVR 1.0 CMOF metamodel that may be used to load and save XMI files (with '.xmi' extension) compliant with the SBVR Exchange Document format.

Model and Diagrams

The UML and Ecore models for this metamodel are checked into CVS in the plugin: org.eclipse.sbvr.xmi.

Class diagrams created from the original SBVR 1.0 metamodel specification:

General observations about the SBVR CMOF model from the specification:

  • SBVR is defined in terms of SBVR language
    • the CMOF metamodel is generated from the SBVR language
    • the CMOF model in the specification was not created or edited using a UML modeling tool
  • There is no use of composite aggregation anywhere in the model
  • All associations own both property ends and none are navigable from the end classes.

Issues

The following issues were discovered while implementing the SBVR CMOF serialization metamodel.

Issue 1: designation::signifier

Class diagram created from the original SBVR 1.0 metamodel specification:

representation::expression has multiplicity [1..1] and is thus required in all specializations. The SBVR 1.0 specification indicates that designation::signifier {subsets expression}, but the {subsets} reference is not included in the CMOF model. Without the subsets reference, the designation subclass will require values for both expression and signifier.

  • Change designation::signifier to add {subsets expression}

The specification also shows that designation::signifier has multiplicity [1..1], but it is [0..*] in the CMOF model. This expanded multiplicity is also incompatible with use of {subsets}.

  • Change designation::signifier multiplicity to [1..1]
