This page provides the required Docuware for the MoDisco v0.10.0 Release Review, as part of the Juno Simultaneous Release.


MoDisco stands for Model Discovery.
It provides a generic and extensible MDE framework to support different reverse engineering scenarios such as modernization, quality assurance, retro-documentation, architecture improvement, etc.
Thus, the focus of MoDisco is on Model Driven Reverse Engineering.
It is an Eclipse Model Development Tools (MDT) project, inside the Eclipse Modeling Project (EMP).


In this release

For the third time, MoDisco is part of an Eclipse Simultaneous Release. The different features provided by MoDisco v0.10.0, as part of Juno, are of three categories.


  • The EMF reference implementation of the core of Abstract Syntax Tree Metamodel (ASTM, an OMG/ADM standard);
  • The EMF reference implementation of Knowledge Discovery Metamodel (KDM, an OMG/ADM standard), corresponding discoverers, a KDM extension for weaving models of code with models of physical resources, a transformation to UML2;
  • The EMF reference implementation of Software Metrics Metamodel (SMM, an OMG/ADM standard);
  • The customizable Model Browser for more efficiently navigating large and complex models discovered from legacy systems;
  • The Discovery Manager for fastest integration of new or existing discoverers;
  • The Discovery Workflow for more easily building discovery chains (including discoverers and transformations);
  • The Generic Discoverer Benchmark for facilitating the execution and visualization of results from benchmarks on various model discoverers (NEW);
  • The Metrics Visualization Builder for automatically generating HTML, SVG or Excel representations of metrics stored in a model.


  • Java
    • The EMF implementation of a metamodel for the full Java language;
    • The corresponding specific Model Browser customization;
    • The complete discoverer for automatically creating Java models from Java source code;
    • An additional discoverer for automatically creating composite models mixing models of Java source code and models of Java physical resources;
    • The complete generator for automatically creating Java source code from Java models;
    • The transformation from Java models to KDM models.
  • JEE
    • The EMF implementation of a metamodel for JSP;
    • The corresponding specific Model Browser customization;
    • The complete discoverer for automatically creating JSP models from JSP source code;
    • A complete discoverer for automatically creating models from web.xml files and ejb-jar.xml (multiple versions);
    • Facilities for developing new discoverers for project deployment descriptor files;
    • A library of queries and facets based on the Java metamodel but dedicated to the extraction of JEE information.
  • XML
    • The EMF implementation of a metamodel for XML (W3C definition);
    • The corresponding specific Model Browser customization;
    • The complete discoverer for automatically creating XML models from XML documents/files.

Use Cases

  • The Model filter plugin allows extracting specific information from Java projects using UML2 models (e.g.; dependency graphs, method calls) and displaying it in a graphical way.
  • The Simple transformation chain plugin shows how to chain components from the two other layers in a workflow that allows, for instance, to produce UML2 models out of Java projects.

Accordance with project plan themes and priorities

  • Perform a restructuring within the MoDisco project in order to plug, when required, the concerned MoDisco components with the corresponding EMFT-EMF Facet project's ones (cf. the Query Manager and Facet Manager components moved from MoDisco). As this restructuring is not 100% complete, previous versions of these two Query Manager and Facet Manager components have been kept in order to ensure the full operation of all MoDisco components.
  • Study and provide means to work on improving the overall scalability of the MoDisco components (cf. the new Generic Discoverer Benchmark).
  • Provide the required service and support on the available components in order to ensure the quality and reliability of the platform.
    • Infrastructure layer (cf. generic components)
    • Technologies & Use Cases layers (cf. technology-specific components)


Non-Code Aspects

The complete MoDisco documentation is available from the MoDisco Wiki page:

  • Project's general information;
  • Reference documentation on the various components (direct access here to the MoDisco User Guide);
  • Version specific information;
  • Additional information on available use cases, as well as incubation and deprecated components;
  • Complementary resources and useful links.

The MoDisco website provides a direct access to all the related resources.


The current MoDisco API situation is detailed in this report.

Testing & Packaging

MoDisco uses a Buckminster-based system to build and promote versions.
Each new build is tested at least with 4.2 (Juno).
Core plugins are provided with dedicated test plugins checking their valid behavior.
MoDisco is integrated into the Juno Release Train since the beginning.

Tool Usability

MoDisco is used for building Model Driven Reverse Engineering solutions to different scenarios such as:

  • Legacy Modernization
  • Quality Assurance
  • Retro-documentation
  • Architecture Improvement
  • Etc


Some components or APIs from the MoDisco previous release builds are now deprecated.


  • Bugzilla snapshot for Juno as of June 04, 2012.

MoDisco-Bugzilla snapshot Juno.png

178 bugs over 842 in total are still opened (click here to get the current Bugzilla status). Most of them are regular bugs and requests for enhancements. As a consequence, we will work on progressively fixing them for the service releases. This will include notably the work on the 5 bugs currently considered as "major". However, note that these bugs concern only some legacy technology-specific components and that none of them is related to the MoDisco core infrastructure.


The MoDisco project has been working in close collaboration with the OMG Architecture Driven Modernization (ADM) Task Force, which has resulted in the EMF implementation of the Abstract Syntax Tree Metamodel (ASTM), Knowledge Discovery Metamodel (KDM) and Software Metrics Metamodel (SMM) specifications.

UI Usability

MDT MoDisco intends to conform to the User Interface Guidelines. The missing items to be fixed in the next version are summarized in
