Introduction to the Objecteering metamodel

Presentation

Welcome to the Objecteering Metamodel User Guide!

The Objecteering metamodel contains the most accurate description of the information managed by Objecteering, as well as its definition and links.

This user guide describes all predefined J classes (Objecteering metaclasses), and constitutes a working base for J programmers and MDA Modeler users wishing to implement new services based on the metamodel (such as model transformation, code or documentation generation, metrics calculation or model requests.

What is a metamodel?
