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 1.0 specification.
- The SBVR CMOF model as published with the OMG specification
- The model used for code generation is available in CVS: org.eclpse.sbvr.xmi/model/SBVR.uml
Class diagrams created from the original SBVR 1.0 metamodel specification:
- concept representation diagram -- Shows a subset of associations between concept, representation, and designation.
- set diagram -- Shows subclasses of set and their associations.
- terminological dictionary diagram -- Shows associations between terminological dictionary, vocabulary, and body of shared meanings.
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:
- concept representation diagram -- Shows a subset of associations between concept, representation, and designation.
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]
