<p>The Model Focusing Tools project is a proposed open source project under the <a
href="">Mylyn Context Project</a>.</p>
The communication channel must be specified. Typically, this is the
"Proposals" forum. In general, you don't need to change this.
<p>This proposal is in the Project Proposal Phase (as defined in the
Eclipse Development Process) and is written to declare its intent and
scope. We solicit additional participation and input from the Eclipse
community. Please send all feedback to the
<a href="">Eclipse Proposals</a>
The Eclipse Mylyn and Modeling projects are two of the most innovative
and widely used projects within Eclipse. They both have strong
communities and high-quality toolsets. Modeling provides high-level,
concept-centeric tools for representing and working with complex
information, and Mylyn provides user-focused, task-centric tools for
organizing and contextualizing complex information. The aim of this
project is to bridge the two technologies, creating a unique toolset
for concept and task-focused interaction with complex information. The
project brings the productivity, integration and traceability
benefits of Mylyn to Eclipse Modeling.
The tools provided by the project also address one of the most
significant challenges to the adoption of Model-Driven Software
Development (MDSD). Models are often represented in diagram
form. Diagrams are much better at depicting complex relationships
between entities than are traditional text-based approaches. But they
have significant disadvantages as well. First, because visual models
capture relationships between entities so well, those relationships
tend to be deeply intertwined, making it difficult to pick out
immediately relevant nodes and relationships from the surrounding
clutter. Second, despite conventional wisdom, diagrams tend to be
information sparse. It can take far more screen real-estate to display
the same information as in text. Ideally, diagrams could self-adapt to
depict just the interesting things, making the best use of available
space. In the initial implementation we mainly tackle the first part
of this challenge. Diagram elements that are not relevant to the task
are hidden and then revealed progressively as the user draws closer to
them in information space.
The scope of this project is to bring Mylyn's task-focused interface
to modeling tools:
<li>Diagram editors, such as for Ecore and UML models</li>
<li>Model Navigators</li>
<li>Model Outlines</li>
<li>EMF generated editors</li>
<li>Other modeling views</li>
The scope expands to other modeling technologies as well, which could include:
<li>Graphiti based editors and views supporting non-EMF based tools</li>
<li>Forms-based editors using EEF</li>
<li>Textual models using XText</li>
<p>It is out of scope to provide integration of modeling
technologies for other Mylyn projects.</p>
<h2>Why Eclipse?</h2>
Answer these two questions: What value does this project bring to the Eclipse
community? What value do you expect to obtain from hosting your project at Eclipse?
What value do you get by having your project at Eclipse over and above the value
of hosting at Eclipse Labs?
<h2>Initial Contribution</h2>
The initial contribution work was developed by <a href="" class="external text" title="" rel="nofollow">Tasktop Technologies</a> and sponsored by <a href="" class="external text" title="" rel="nofollow">Ericsson</a> in the context of the <a href="" class="external text" title="" rel="nofollow">Modeling Platform Industrial Working Group</a> It is publicly available under the EPL v1.0 and pending contribution is hosted at <a href="" class="external free" title="" rel="nofollow"></a>.
The initial contribution is a full-featured Mylyn bridge for EMF. It
provides a focused mode for diagrams that shows only the elements
related to the task-at-hand, dramatically reducing information
overload for engineers working on large models. In addition, the
task-focused interface extensions provide Mylyn's one-click
multitasking facilities for working with models, ensuring that
developers can instantly recover from interruptions, and share
model-specific expertise, when working with models in addition to what
Mylyn already provides for engineers working with source code
(see <a href=""
class="external text"
rel="nofollow">for details</a>). Currently supported modeling tools
<li>Ecore Models within the Ecore Tools diagram editor and project
explorer extensions.</li>
<li>UML Class models using the Papyrus modeling tools.</li>
The contribution also provides support at the API level allowing
integrators to implement their own Mylyn support for existing Ecore
models and GMF editors
(see <a href="">for details</a>). Current service provider interfaces
are extensible for:
<li>Arbitrary domain models, including EMF-based models.</li>
<li>Generic GMF-based diagrams.</li>
The initial contribution has been developed using the conventions and development process of the Mylyn Context project.
<h2>Legal Issues</h2>
The initial contribution is licensed under the EPL. We don't expect
any problems during the IP review.
