Eclipse OCL (Object Constraint Language) 1.3.0

Release Date
Deliverables

The release deliverables have the same form as is found in most Eclipse projects, namely:

  • MDT OCL source code release, available as versions tagged "R1_3" in the project's CVS repository.
  • MDT OCL SDK (includes runtime, sources, examples, and documentation) (downloadable and update site).
  • MDT OCL runtime binary distribution (downloadable and update site).
  • MDT OCL stand-alone binary distribution (downloadable).
  • MDT OCL tests (downloadable)
Compatibility

Compatibility of Release 1.3: The MDT OCL project will be developed in parallel, and released simultaneously, with the following projects. As stated above, each milestone release of the MDT OCL project will be compatible with the corresponding milestones for each of these projects, and delivered the appropriate offset.

  • Eclipse Platform SDK version 3.5
  • Eclipse Modeling Framework (EMF) version 2.5
  • Model Development Tools (MDT) UML2 version 2.3

Therefore, the MDT OCL initial release will be compatible with these versions and will publish binary and source compatibilities with migration guides on subsequent releases.

Internationalization

The Eclipse Platform is designed as the basis for internationalized products. The user interface elements provided by the Eclipse SDK components, including dialogs and error messages, are externalized. The English strings are provided as the default resource bundles. As a result, the MDT OCL project will provide English strings in its default bundles and be localized to a subset of those locales offered by the Platform. This plan will be updated to indicate which locales will be provided and the time frame for availability.

Target Environments

In order to remain current, each Eclipse release targets reasonably current versions of the underlying operating environments. The Eclipse Object Constraint Language (MDT OCL) project depends upon on the Platform and other projects, which are mostly "pure" JavaTM. The 3.5 release of the Eclipse Platform Project is written and compiled against version 1.4 of the Java Platform APIs, and targeted to run on version 1.4 of the Java Runtime Environment, Standard Edition. MDT OCL will target the same Java version as EMF and UML2, which currently require Java 5. Eclipse Platform SDK 3.5 will be tested and validated on a number of reference platforms. MDT OCL will be tested and validated against a subset of those listed for the platform.

Themes

Release Currency

The MDT OCL project will maintain currency with its dependencies, in particular advances in the EMF and MDT UML2 projects. Additionally, as an implementation of the OMG's OCL 2.0 specification, the MDT OCL project will maintain currency with the revised 2.1 specification.

Extensibility

The Object Constraint Language is re-used and extended by other language specifications, in particular the OMG MOF® Query/View/Transformation family of languages. This theme addresses the need for extensibility of the MDT OCL language implementation and APIs.

Appealing to a Broader Community

There are a few fairly routine capabilities which, historically, MDT OCL has not supplied because of its narrow focus on parsing and evaluating OCL text. User demand shows the value of providing the EMF.Edit plug-ins, for example, as well as a more flexible feature structure.
