| <p> |
| This document lays out the feature and API set for the |
| sixth annual release of the Eclipse Object Constraint Language (MDT OCL) |
| Project, version 3.1.0 or 3.2.0. The Indigo release will be 3.1.0 unless an interim |
| release is required in order to provide intermediate support in the event that EMF |
| or UML2 deviate from Helios compatibility during the Indigo cycle. |
| |
| A late requirement to use Xtext rather than IMP to support editing meant that many 3.0.0 facilities |
| were not fully developed in time for release 3.0.0. Resolution of evaluator issues and library usability |
| were held back, and the editors provided only as examples. Interim milestones, or if necessary an interim |
| 3.1.0 release, are intended to resolve quality issues in the editors. |
| The 3.1.0 or 3.2.0 release (for Indigo) should prepare for full integration |
| of the new editors and make the library model-driven. Switchover of the old APIs to the new functionality |
| and renaming of examples plugins should occur immediately after Indigo so that OCL clients have the |
| entire Indigo+1 development cycle to exploit the enhancements that will appear in 4.0.0. |
| |
| New external APIs are planned to provide interchangeability with alternate OCL products. |
| The existing external APIs should be unaffected, will be deprecated after Indigo, but may be |
| retained indefinitely as simple wrappers on the new APIs. |
| |
| New semi-internal parsing APIs are planned to resolve a number of hard problems and to provide |
| compatibility between the LPG and Xtext parsers. The existing semi-internal parsing APIs will |
| be retained in so far as possible, but will be deprecated in Indigo. The project team anticipates |
| working with major consumers in the release after Indigo to assist in migration to the new APIs. |
| </p> |
| <p> |
| <i><b>Note</b> that, since the |
| <a href="http://www.omg.org/cgi-bin/doc?ptc/10-02-01.pdf">OMG OCL 2.2</a> |
| standard suffers from significant ambiguities and conflicts making a compliant implementation impossible, |
| <b>MDT OCL 3.1.0</b> release is best endeavours to establish a coherent interpretation |
| of the OMG OCL 2.2 and to prototype resolutions for the OMG OCL 2.3 standards. Two of the MDT/OCL |
| committers are also members of the OMG Revision Task Force that resolves the specification issues.</i> |
| </p> |
| <p> |
| </p> |
| <p> |
| <i> |
| A guide aimed to help users to migrate from MDT OCL 3.0.0 releases to MDT OCL 4.0.0 release |
| will be provided. |
| </i> |
| </p> |
| </div><h2><a name="release_deliverables">Release Deliverables</a></h2><div> |
| The release deliverables for the MDT OCL 3.1 or 3.2 release have the same form as |
| is found in most Eclipse projects, namely: |
| <ul> |
| <li>MDT OCL SDK (includes runtime, sources, examples, and documentation) (downloadable and update site).</li> |
| <li>MDT OCL runtime binary distribution (downloadable and update site).</li> |
| <li>MDT OCL stand-alone binary distribution (downloadable).</li> |
| <li>MDT OCL tests (downloadable)</li> |
| <li>MDT OCL examples (downloadable)</li> |
| </ul> |
| MDT OCL 3.1.0 source code will be available as versions tagged "R3_1" in the project's CVS repository. |
| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="release_milestones">Release Milestones</a></h2><div> |
| Release milestones occur at roughly 6 week intervals and follow the |
| Platform milestone releases by approximately 1 week; that is, until the |
| final 3.7 release of the Platform, upon which MDT OCL and other projects |
| will release simultaneously. As MDT OCL is a dependency of numerous |
| other projects, MDT OCL Core will deliver its milestones at the +1 |
| schedule in accordance with the schedule below. MDT OCL Tools will deliver |
| at the +3 schedule (two days later). |
| </div><table border="1" align="center"><tr><td><b>3.1.0M1</b></td><td>Monday 18 August 2010</td><td/></tr><tr><td><b>3.1.0M2</b></td><td>Monday 27 September 2010</td><td/></tr><tr><td><b>3.1.0M3</b></td><td>Monday 8 November 2010</td><td/></tr><tr><td><b>3.1.0M4</b></td><td>Monday 13 December 2010</td><td/></tr><tr><td><b>3.1.0M5</b></td><td>Monday 31 January 2011</td><td/></tr><tr><td><b>3.1.0M6</b></td><td>Monday 14 March 2011</td><td><div>API freeze</div></td></tr><tr><td><b>3.1.0M7</b></td><td>Monday 2 May 2011</td><td><div>Feature Freeze</div></td></tr><tr><td><b>3.1.0RC1</b></td><td>Monday 16 May 2011</td><td/></tr><tr><td><b>3.1.0RC2</b></td><td>Monday 23 May 2011</td><td/></tr><tr><td><b>3.1.0RC3</b></td><td>Monday 30 May 2011</td><td/></tr><tr><td><b>3.1.0RC4</b></td><td>Monday 6 June 2011</td><td/></tr><tr><td><b>Indigo</b></td><td>Monday 22 June 2011</td><td/></tr></table><div> |
| MDT OCL may produce interim maintenance releases in addition to these in |
| order to satisfy clients requests. |
| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="target_environments">Target Environments</a></h2><div> |
| 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" Java. The 3.7 |
| release of the Eclipse Platform Project is written and compiled |
| against version 5.0 of the Java Platform APIs, and targeted to run on |
| version 5.0 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 3.7 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. |
| </div><h3>Internationalization</h3> |
| <div> |
| 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. |
| </div> |
| <p><a href="#toc">Table of Contents</a></p><h2><a name="compatibility">Compatibility with Previous Releases</a></h2><div> |
| The MDT OCL 3.1 or 3.2 project |
| will be developed in parallel, and released simultaneously, with the |
| following projects. |
| <ul> |
| <li>Eclipse Platform SDK version 3.7</li> |
| <li>Eclipse Modeling Framework (EMF) version 2.7</li> |
| <li>Model Development Tools (MDT) UML2 version 3.2</li> |
| </ul> |
| <p> |
| As described above, the MDT OCL 3.1.0 release should address usability of the editors. |
| The main OCL plugins should be unaffected, |
| but the associated examples plugins may be revised significantly. |
| |
| Again as described above, the MDT OCL 4.0.0 release for Indigo+1 will introduce significant new APIs |
| with a view to deprecating existing ones, which will be retained whereever possible to |
| allow consumers to migrate with assistance after Indigo. |
| </p> |

| </div><p><a href="#toc">Table of Contents</a></p><h2><a name="themes_and_priorities">Themes and Priorities</a></h2><div> |
| A list of project requirements and agreed upon |
| implementation time frames is found in this document. For the |
| milestones listed in this document, a set of overall themes is used |
| to indicate what major set of functionalities is to be concentrated |
| on for each. These themes are presented below, while the requirements |
| document and associated Bugzilla entries are left to those wanting |
| more detailed information on each. |
| </div><h3>Compliance</h3><div> |
| This theme addresses issues related to the OMG OCL 2.2 specification adoption. The bugs related to the inherited deviations |
| of the MDT OCL implementation from the OCL 2.0 specification (and consequently, OCL 2.2) also appear here. |
| |
| It is anticipated that fixes for the majority of the target 4.0.0 will appear in the |
| revised MDT/OCL Examples code in 3.1.0, but this will not be promoted to replace the |
| traditional behaviour until 4.0.0. |
