Eclipse MoDisco 1.2.0

The MoDisco architecture is composed of three different layers:

Infrastructure

• 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;
• The Metrics Visualization Builder for automatically generating HTML, SVG or Excel representations of metrics stored in a model.

Technologies

• 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.

The project makes good use of several different Eclipse projects (mainly Modeling projects). There is notably an historical link with the EMF Facet project (as it is a spin-off from MoDisco).
