Legacy systems embrace a large number of technologies, making the development of tools to cope with legacy systems evolution a tedious and time consuming task.

As modernization projects face with both technologies combination and various modernization situations, model-driven approaches and tools offer the requisite abstraction level to build up mature and flexible modernization solutions.

What is MoDisco ?

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

Quality Assurance: verifying whether an existing system meets the required qualities (detection of anti-patterns in existing code and computation of metrics.)
Documentation: extraction of information from an existing system to help understanding one aspect of this system (structure, behaviour, persistence, data-flow, change impact , etc).
Improvement: transformation of an existing system to integrate better coding norms or design patterns.
Migration: transformation of an existing system to change a component, the framework, the language, or its architecture

In each case, 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, ...)

MoDisco aims at supporting these three phases by providing :

Metamodels to describe existing systems
Discoverers to automaticaly 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 process

Description

To facilitate reuse of components between several use-cases, 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 one specific modernization use case.

Infrastructure : generic components independent from any legacy technology.

See MoDisco architecture detail...

Infrastructure

All the components of this layer are available as plugins and provided in one single Eclipse feature

Feature Infrastructure 0.7 contains :

reference implementations of OMG/ADM metamodels (KDM and SMM)
a transformation from KDM to UML
a model browser to facilitate the navigation through a complex model
a discovery manager to register and integrate discoverers into Eclipse
a discovery workflow to easily chain several discoverers and transformators
a sources discoverer which creates a KDM model describing the files and directories of an existing project
a metrics vizualizations builder which generates HTML, SVG or Excel outputs from a model containing metrics

Technologies

All the components of this layer are available as plugins and provided in several Eclipse features : one for each technology.

Feature J2SE5 0.7 contains:

a complete metamodel for the Java language
a complete discoverer to create J2SE5 models from Java source code contained in a Java project
a transformation from J2SE5 models to KDM

Feature JavaAST 0.2 contains:

a complete metamodel for the Java language
a complete discoverer to create JavaAST models from Java source code contained in a Java project

Note : a new component merging J2SE5 and JavaAST has been developped and will be released soon

Feature CSharp 0.6 contains:

a complete metamodel for the C# language
a transformation from CSharp models to KDM

Use-Cases

All the components of this layer are available as plugins

Model Filter : creation of a UML model containing dependencies for a Java classes selected in the Eclipse environment
Bugzilla metrics : conversion of Bugzilla data into Excel, HTML or SVG documents
BIRTSampleDB : extraction of model from a BIRT database.

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

Project plan

Additional components are planned to be added to MoDisco.

See the project's plan ...

-The [http://www.eclipse.org/gmt/modisco/ MoDisco] ('''Model Discovery''') component is an Eclipse/[[GMT]] component which has been initiated by the '''AtlanMod Team''', [http://www.inria.fr/ 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.
+As modernization projects face with both technologies combination and various modernization situations, model-driven approaches and tools offer the requisite abstraction level to build up mature and flexible modernization solutions.

-== Overview  ==
+== What is MoDisco&nbsp;?  ==
-The goal of [http://www.eclipse.org/gmt/modisco/ 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.
+MoDisco provides an extensible framework to develop '''model-driven tools''' to support use-cases of '''existing software modernization'''&nbsp;:
-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 [[MoDisco/Architecture|architecture of MoDisco]], integrating OMG/ADM standards such as [[MoDisco/KDM|KDM]], will allow integrating all these contributions.
+*'''Quality Assurance''': verifying whether an existing system meets the required qualities (detection of anti-patterns in existing code and computation of metrics.)
+*'''Documentation''': extraction of information from an existing system to help understanding one aspect of this system (structure, behaviour, persistence, data-flow, change impact , etc).

-<br> 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.
+<br> In each case, modernizing an existing software system implies:
-== Definitions  ==
+*'''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, ...)
-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):
+MoDisco aims at supporting these three phases by providing&nbsp;:
-*'''Model discovery''': the general process composed of the two following metamodel-driven steps:
+*'''Metamodels''' to describe existing systems
-**the retrieval of the information from an existing system according to specific metamodels
+*'''Discoverers''' to automaticaly create models of these systems<br>
-**the injection of this information into one or several models that conform to the same specific metamodels.
+*'''Generic tools''' to understand and transform complex models created out of existing systems
+*'''Use-cases''' illustrating how MoDisco can support modernization process
-*'''Discoverer''': an implementation (i.e. a program, a ''tool'', etc) that has been designed for performing a model discovery process.
