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.
Contents
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 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
Description
To facilitate reuse of components between several use-cases, MoDisco is organized in three layers:
|
|
See MoDisco architecture detail...
Infrastructure
All the components of this layer are available as plug-ins 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 transformers
- a sources discoverer which creates a KDM model describing the files and directories of an existing project
- a metrics visualizations builder which generates HTML, SVG or Excel outputs from a model containing metrics
Technologies
All the components of this layer are available as plug-ins and provided in several Eclipse features: one for each technology.
Feature Java 0.6 contains:
- a complete metamodel for the Java language
- a complete discoverer to create Java models from Java source code contained in a Java project
Note: a transformation from Java models to KDM will be released soon.
The Java component merges the J2SE5 and JavaAST older components which are still available :
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
Feature CSharp 0.6 contains:
- a complete metamodel for the C# language
- a transformation from CSharp models to KDM
Feature XML 0.6 contains:
- a complete metamodel for the XML standard, subsetting W3C concepts
- a complete discoverer to create XML models from XML files
Use-Cases
All the components of this layer are available as plug-ins
- Simple Transformations Chain: creation of a UML model from a Java project, just aggregating discoverers from Infrastructure and Technologies layers.
- Model Filter: creation of a UML model containing dependencies for a Java classe selected in the Eclipse environment.
- Bugzilla metrics: conversion of Bugzilla data into Excel, HTML or SVG documents.
- BIRTSampleDB: discovery of model from a BIRT database.
- Performance-Annotated UML2 State Chart: discovery of performance information from an Excel file, computation of metrics using this information and application of them to a UML2 model using a Performance profile.
Incubation
The followings are components also available from MoDisco. However, they are not currently part of the standard MoDisco build.
The MOMOCS European Project provides:
- the MOMOCS Metamodel and corresponding Simple Editor
- the MOMOCS Transformation Tool
- the Travel Agency use case
- the Polimi Blog use case
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
Roadmap
Additional components are planned to be added to MoDisco.
