| <introduction> |
| <html:div> |
| This document lays out the feature and API set for the |
| 2.0.0 release of the EMF Compare project. |
| This project plan inherits from the Modeling Project Plan, |
| which should be referenced when consulting this individual project plan. |
| </html:div> |
| </introduction> |
| |
| <release_deliverables> |
| <html:div> |
| The release deliverables have the same form as is found in most Eclipse projects. Namely: |
| <html:ul> |
| <html:li> |
| EMF Compare source code release, |
| available as versions tagged with "R2_0" in the project's GIT repository. |
| </html:li> |
| <html:li> |
| EMF Compare SDK, |
| which includes runtime, sources, examples, and documentation, |
| and is available as a download or on the update site. |
| </html:li> |
| <html:li> |
| EMF Compare binary distribution, |
| available as a download or on the update site. |
| </html:li> |
| </html:ul> |
| </html:div> |

| <release_milestones> |
| <preamble> |
| <html:div> |
| The 2.0 release for EMF Compare is planned outside of the platform release train. |
| It was initially planned to align with the Juno release train, but was postponed |
| in order not to confuse users as to what was the "Juno" version. |

| <postamble> |
| <html:div> |
| EMF Compare will produce maintenance releases to align with the Juno Service Releases |
| which includes the Eclipse Platform's 4.2.1 and 4.2.2 releases.<html:br/> |
| They will be released a while after the Juno SR release trains in order not to |
| confuse adopters.<html:br/> |
| EMF Compare may produce additional interim maintenance releases.<html:br/> |
| Maintenance releases will only be published if they contain new fixes. |
| </html:div> |
| </postamble> |
| </release_milestones> |
| |
| <target_environments> |
| <html:div> |
| In order to remain current, each Eclipse release targets reasonably current versions of the underlying operating environments. |
| The EMF Compare project depends upon on the Platform,which is mostly "pure" Java™.The 4.2 release of the Eclipse Platform Project |
| is written and compiled against version 1.5 of the Java Platform APIs, and targeted to run on version 1.5 of the Java Runtime Environment, Standard Edition. |
| EMF Compare rely on EMF Core which is written and compiled against version 1.5 of the Java Platform APIs., |
| EMF Compare relies on Java 5.<html:br/> |
| Eclipse Platform SDK 4.2 will be tested and validated on a number of reference platforms.<html:br/> |
| EMF Compare will be tested and validated against a subset of those listed for the platform.<html:br/> |
| <html:br/> |
| Given that there is no operating system dependent code in EMF Compare, it's expected that EMF Compare will work anywhere the Eclipse Platform does. |
| </html:div> |
| <internationalization> |
| <html: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.<html:br/> |
| The English strings are provided as the default resource bundles.<html:br/> |
| Similarly, the EMF Compare project will externalize all its user interface elements, |
| provide English strings for them in its default bundles, |
| and localize a subset of the locales offered by the Platform.<html:br/> |
| The download page will provide the details as they become available. |
| </html:div> |
| </internationalization> |
| </target_environments> |
| |
| <compatibility_with_previous_releases> |
| <html:div> |
| EMF Compare 2.0 is a full overhaul of the project, including its design and architecture.<html:br/> |
| As such, the project's API is not compatible with its previous 1.* versions. A migration guide |
| will be provided in order to ease the adoption effort to this new version.<html:br/> |
| |
| EMF Compare is developped with and targets the following projects : |
| <html:ul> |
| <html:li> |
| Eclipse Platform SDK version 4.2 |
| </html:li> |
| <html:li> |
| EMF Core 2.8 |
| </html:li> |
| </html:ul> |
| The ultimate EMF Compare release will be compatible with the released version of its dependencies |
| and will publish binary and source compatibilities with migration guides on subsequent releases. |
| </html:div> |

| <themes_and_priorities> |
| <preamble> |
| <html:div> |
| A list of project goals and agreed upon implementation time frames is found in this document.<html:br/> |
| For the milestones listed in this document, a set of overall themes is used to indicate what major |
| set of functionalities is expected to be the focus of each.<html:br/> |
| These themes are presented below, while the goals of the associated Bugzilla entries are available |
| for more detailed information. |
| </html:div> |
| </preamble> |
| <theme name="Architecture Overhaul"> |
| <description> |
| <html:div> |
| <html:p> |
| EMF Compare 1.* presents limitations that cannot be worked around in order to fix some of the |
| problems identified with the project : merging, scoping, memory performance...<html:br/> |
| Furthermore, this version of EMF Compare proposed a somewhat complex API to its clients and |
| we cannot easily re-design this to ease the project's use. |
| </html:p> |
| <html:p> |
| One of the main goals of EMF Compare 2 is to do a complete overhaul of the project's architecture |
| in order to lift these limitations and clarify the API we provide to our adopters.<html:br/> |
| Among other changes, the core model of EMF Compare will be simplified for clarity, and the main |
| interfaces to launch comparisons and merges of two or three models will be made less convoluted. |
| </html:p> |
| </html:div> |
| </description> |
| </theme> |
| |
| <theme name="Support for Large models"> |
| <description> |
| <html:div> |
| <html:p> |
| Though this was also one of the priorities of the 1.3 release that shipped along with the Juno |
| release train, this is one of the points for which we had to make compromises in order to |
| cope with the aforementioned limitations of the 1.* stream.<html:br/> |
| EMF Compare 1.3.0 did propose a lot of improvements on the scalability front, but we could not |
| ensure scalability for millions of elements as can be seen in most "real-life" models used |
| by our adopters in production. |
| </html:p> |
| <html:p> |
| EMF Compare 2.0 will provide the mandatory architecture and API changes required for the |
| project to handle such a scale of input models. Namely, it will propose a "scope" feature that |
| will be fully customizable so that the subsequent version of EMF Compare, 2.1, can provide |
| the fragmented scope that will be able to handle extremely large input models. In short, EMF |
| Compare will be able to function with time and memory footprints dependent on the number of |
| actual differences instead of being dependent on the input models' size. |
| </html:p> |
| </html:div> |
| </description> |
| </theme> |
| |
| <theme name="Integration with the Eclipse UI"> |
| <description> |
| <html:div> |
| <html:p> |
| EMF Compare 1 presented a user interface mimicking the standard Eclipse compare UI, but which |
| was not really integrated with it : folder comparison was not using EMF Compare to show |
| structural differences, the viewers were our own, the displayed elements weren't compatible with |
| what Eclipse Compare was expecting... |
| </html:p> |
| <html:p> |
| EMF Compare 2 is now deeply integrated with Eclipse Compare, reusing its API in each and every |
| possible means. This means that the icons will be the exact same as the standard "text" |
| comparisons, the behavior will be closer to Eclipse compare (notably on folder comparisons and |
| viewer switching)... |
| </html:p> |
| </html:div> |
| </description> |
| </theme> |
| |
| <theme name="Performance Enhancements"> |
| <description> |
| <html:div> |
| <html:p> |
| Some performance bottlenecks in EMF Compare 1.3 have been identified yet cannot be solved without |
| fully re-thinking the comparison process. EMF Compare 2.0 will provide these enhancements and will |
| be faster than the 1.* stream even without the aforementioned changes that are planned for version |
| 2.1. |
