This work is developed by Atos Origin and sponsored by Airbus in the context of OPEES.

Proposal

Topcased proposes for years now some components tailored for industrial usage around the verification of static semantics of models based on MDT OCL:

  • An OCL evaluator, aiming to support and make the development of OCL rules easier. This view offers:
    • Choosing of a test model or (auto-)adaptating to the selection
    • OCL auto-completion
    • Decomposing complex OCL step by step to make debugging easier

  • An OCL checker that:
    • Evaluate a list of constraints and queries on any EMF model

    • Provides the results in either a GUI or the Problem View, or in reports based on templates
    • Can be called in GUI or batch mode

    • Can raise errors, warnings, information and rule failure messages

More information about those tools here.

The goal of this project is to contribute these tools to MDT OCL, and to propose a few improvements as:

  • Advanced meta-data around OCL rules: dependencies between rules, error messages, model scope.
  • Auto-generation of OCL verification plug-ins based on rules files.
  • Integration with the new MDT OCL rules editor.

Schedule (dates tentative)

The project is scheduled to be ready on December, 2011 as part of MDT OCL.
