MoDisco provides an extensible framework to develop model-driven tools to support use-cases of existing software modernization.

• See MoDisco home page

Overview

Modernizing an existing software system implies :

• Describing the information extracted out of the artifacts of this system
• Understanding the extracted information in order to take the good modernization decisions
• Transforming this information to new artifacts facilitating the modernization (metrics, document, transformed code, ...)

To support these activities, MoDisco aims at providing :

• Metamodels to describe existing systems
• Discoverers to automatically create models of these systems
• Generic tools to understand and transform complex models created out of existing systems
• Use-cases illustrating how MoDisco can support modernization processes

To facilitate reuse of components between several modernization solutions, MoDisco is organized in three layers:

Use-Cases: tools providing a solution for a specific modernization use-case. Technologies: components dedicated to one legacy technology but independent from any specific modernization use case. Infrastructure: generic components independent from any legacy technology.

Relationship with other Eclipse Projects

MoDisco reuses lots of EMP projects:

• EMF to describe and manipulate models of existing systems.
• M2M to implement transformation of models into other models
• M2T to implement generation of text (documentation or code)

MoDisco also reuses other projects such as:

• JDT to create models out of Java source code

Team

MoDisco was started by the AtlanMod Team (Inria, Mines de Nantes & LINA), and then strongly supported by Mia-Software:

• Hugo Bruneliere - AtlanMod (project co-leader)
• Fabien Giquel - Mia-Software (project co-leader)
• Grégoire Dupé - Mia-Software (committer)
• Nicolas Bros - Mia-Software (committer)
• Gabriel Barbier - Thales (committer)
• Frédéric Madiot - Obeo (committer)

MoDisco was rescued from termination by:

• Edward Willink - Willink Transformations Ltd.
