This page summarizes modifications to the SBVR 1.0 CMOF metamodel that result in a more usable EMF-based implementation and API for tool development. An alternative EMF resource handler will be provided that loads and saves XMI files (with '.xmi' extension) compliant with the SBVR 1.0 specification. The modified metamodel will load and save files using the '.sbvr' file extension.

This page describes the SBVR metamodel used for tool development. It is different from the [[SBVR Exchange Metamodel]] that is used only for XMI serialization to the SBVR exchange document format. The SBVR Tools Metamodel is optimized for development of tools that create and use SBVR vocabularies and rules. This project will implement a feature for transforming models to/from the SBVR exchange document metamodel.

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.
+
  
The result of this design approach is that there are several challenges in producing a usable EMF-based implementation and a 'good' developer API.

In general, no associations or attributes are removed from the original metamodel.  Additional composite properties are added to create a hierarchical ownership structure that enables EMF commands and validation based on containment. Operations are added that derive values, support validation, and improve developer APIs.

[edit] Overview

This page describes the SBVR metamodel used for tool development. It is different from the SBVR Exchange Metamodel that is used only for XMI serialization to the SBVR exchange document format. The SBVR Tools Metamodel is optimized for development of tools that create and use SBVR vocabularies and rules. This project will implement a feature for transforming models to/from the SBVR exchange document metamodel.

[edit] Design Rationale

These pages describe more detail about the design rationale for the SBVR Tools Metamodel.

[edit] Model and Diagrams

The UML and Ecore models for this metamodel are checked into CVS in the plugin: org.eclipse.sbvr. This model is an incomplete work-in-progress and will be updated until a first release is finished.
