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.
See also:
Model and Diagrams
The UML and Ecore models for this metamodel are checked into CVS in the plugin: org.eclipse.sbvr.xmi.
- Based on the SBVR CMOF model as published with the OMG specification
Class diagrams created from the original SBVR 1.0 metamodel specification:
- conceptual schema and fact model diagram -- Associations between conceptual schema and fact model
- concept representation diagram -- Subset of associations between concept, representation, and designation
- set diagram -- Subclasses of set and their associations
- terminological dictionary diagram -- 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]
