< To: MDT

This page provides the required docuware for the MDT OCL 3.0.0 Release Review, as part of the upcoming Helios Simultaneous Release.

Overview

OCL is an implementation of the Object Constraint Language (OCL) OMG standard for EMF-based models.

The OCL component provides the following capabilities to support OCL integration:

• Defines APIs for parsing and evaluating OCL constraints and queries on EMF models.
• Defines an Ecore implementation of the OCL abstract syntax model, including support for serialization of parsed OCL expressions.
• Provides a Visitor API for analyzing/transforming the AST model of OCL expressions.
• Provides an extensibility API for clients to customize the parsing and evaluation environments used by the parser.

Features

New in this release

• Elimination of deviations from the OMG standard.
• Internal improvements and upgrade to the newest LPG parser version.
• OCL annotations are supported in Ecore models
• OCL Editor support in examples.

Non-Code Aspects

The complete MoDisco documentation is available from the Wiki:

• General documentation on the various components;
• Version specific information;
• Additional information on available use cases, as well as incubation and deprecated components.

The Help plugins are automatically generated from the content of the Wiki.
The MoDisco website provides a direct access to all the related resources.

Testing & Packaging

MoDisco uses the Modeling Project Releng system to build and promote versions.
Each new build is tested at least with Eclipse 3.6 (Helios).
Core plugins are provided with dedicated test plugins checking their valid behavior.
MoDisco is integrated into the Helios Release Train since December 2009.
It is also part of the Amalgamation Modeling Package for Helios.

Community & Support

• Strong collaboration with the OMG Architecture Driven Modernization (ADM) Task Force
  • MoDisco book chapter in Information Systems Transformation: Architecture-Driven Modernization Case Studies by The Morgan Kaufmann/OMG Press (pages 365-400)
  • Presentation at upcoming 2nd Biannual Symposium On Eclipse Open Source Software & OMG Open Specification on June, 22 2010
• Several presentations and demos at EclipseCon (2009 & 2010) and Eclipse Summit Europe (2009)
• Dedicated MoDisco newsgroup
• Bugzilla (v0.8.0 only, snapshot taken on the 27th of May 2010):

IP Issues

The Eclipse IP Process has been strictly followed and all plugins contain the appropriate about.html and license files.
The MoDisco IP Log is available from http://www.eclipse.org/projects/ip_log.php?projectid=modeling.mdt.modisco

• Some third-party libraries are used (cf. corresponding validated CQs)

All MoDisco content is released under EPL.
