MoDisco

< To: GMT

The MoDisco (Model Discovery) component is an Eclipse/GMT component which has been initiated by the AtlanMod Team, INRIA. The aim of the GMT project is to produce a set of prototypes in the area of Model Driven Engineering (MDE). The MoDisco project acts in this way by providing a support for model-driven reverse engineering, i.e. principles, methodologies and tooling.


Overview

The goal of MoDisco (Model Discovery) is to allow practical extractions of models from legacy systems. Because of the widely different nature and technological heterogeneity of legacy systems, there are several different ways to extract models from such systems. MoDisco proposes a generic and extensible metamodel-driven approach to model discovery. A basic framework and a set of guidelines are provided to the Eclipse contributors to bring their own solutions to discover models in various kinds of legacy.

Due to the highly diversified nature of the considered legacy, MoDisco is a collaborative component involving many organizations. Each of them will bring its own expertise in a given area. The modular architecture of MoDisco, integrating OMG/ADM standards such as KDM, will allow integrating all these contributions.

As a GMT component, MoDisco will make good use of other GMT components or solutions available in the Eclipse Modeling Project (EMF, M2M, M2T, GMF, TMF, etc), and more generally of any plugin available in the Eclipse environment.

Definitions

We provide here a set of definitions for the main different concepts which are relevant within the context of MoDisco (i.e. which are related to model discovery and model-driven reverse engineering):

  • Model discovery: the general process composed of the two following metamodel-driven steps:
    • the retrieval of the information from an existing system according to specific metamodels
    • the injection of this information into one or several models that conform to the same specific metamodels.
  • Discoverer: an implementation (i.e. a program, a tool, etc) that has been designed for performing a model discovery process.

Available Components

MoDisco already provides an initial set of use cases to illustrate metamodel-driven reverse engineering.

You can develop your own use-cases by using the components available with MoDisco.

Metamodels

MoDisco provides several metamodel implementations dedicated to model-driven reverse-engineering.

See complete list ...

Discoverers

MoDisco provides several discoverers to get models out of existing systems.

Model Editor

MoDisco provides a generic browser to inspect the contents of models created by the discoverers. This browser is an extension of the ECore editor to facilitate the navigation through objects and links contained by a model.

Discoverers Manager

MoDisco provides a framework to define a standard contract for discoverers and generic tools to manipulate them.
