Atom Syndication Format in EMF

By Peter Nehrer, 2006-06-09
This project aims to provide an EMF-based model for representing the Atom Syndication Format. Its deliverables include an extensible Ecore model along with a set of generated implementation classes (both model and editing support). The Ecore model closely follows the official Atom Syndication Format Specification. Content rules that cannot be represented in the model itself are encapsulated in a set of external validators. This gives the model the ability to represent incomplete Atom documents or those that are not 100% standard compliant.

EMF Persistency Layer using Hibernate/JPOX with support for EJB3-EAnnotations

By Martin Taal, 2006-06-08
Elver EMF Store is a persistency solution for EMF using Hibernate or JPOX/JDO 2.0. It supports automatic creation of EMF to Relational Mappings and the related database schemas. The solution also contains a runtime layer to support specific EMF features. EMF Objects can be stored and retrieved using advanced queries (HQL or JDOQL). EMF resource implementations are provided for integration with EMF Editors. The persistence logic and mapping can be controlled using EJB3-like annotations. Most of the EJB3 mapping standard is supported.

 Sympedia GenFw Generator Framework Review, 
by Philipp W. Kutter, 2006-05-25
We have been using GenFw productively in a large project in the financial industry over the last 3 months. 
Originally we have chosen GenFw because it allowed to do certain things (like project specific code 
formatting/adding removing templates) which where not working in EMF back then. The usage of GenFw was 
straight forward, and it helped us nicely manage our custom JET templates. The option to do EMF without 
merging is something very interesting in very large projects, like the one we worked on. The developer 
of GenFw, Eike Stepper did a tremendous job porting his framework back from Eclipse 3.2/EMF 2.2 to 
Eclipse 3.1/EMF 2.1. Without this special effort, our EMF introduction would have been canceled by 
the management. In the meantime the two main issues with EMF (formatting, adding/removing templates) 
are solved, and our client was ready to move on to 3.2. Currently we investigate the usage of GenFw 
for pure code generation with Jet Templates, which are triggered by OCL rules. Last but not least, 
I would like to mention that the tutorials where great to get our people started with the framework.

XML Processing Instruction support

By Peter Nehrer, 2006-12-05
This small project provides support for modeling XML Processing Instructions in EMF. It consists of a model for representing Processing Instructions and a customized XMLResourceImpl, which handles loading and saving of PIs. Currently, Processing Instructions are not supported natively in EMF.

To add support for Processing Instructions to your model, modify your model's Resource implementation to subclass PIResourceImpl instead of XMLResourceImpl. Furthermore, add PIItemProviderAdapterFactory to your ComposedAdapterFactory instances. When a Processing Instruction is encountered in the context of a mixed-content element (or the document root), it will be added to the corresponding feature map, much like text, comments, and cdata sections.

The code was compiled against Eclipse 3.2.1 and EMF 2.2.1 in J2SE-1.4 execution environment.

Frameworks

MetaDiff

By Mark Kofman, 2005-08-02
MetaDiff is a generic model comparison solution. Generic, in a sense, that it should make possible to compare models based on different meta-models specified by EMF. It is important to point out that result is not a tool but a framework. In addition to model comparison functionality, framework should also give a possibility to extend available comparison algorithms, and provide practical way of working with different meta-models.

 TopcaseD Review,
by Philipp W. Kutter, 2008-01-08
 We use the TopcaseD ECore editor since years, and at the moment we run version 1.2 under Eclipse 3.4M4 and EMF 2.4.
Everything works perfectly, and we are looking forward to migrate to the successor of the TopcaseD ECore editor, the forthcomming official Eclipse MDT Ecore editor.
Congratulations to the TopcaseD project both for their product, and the successful integration with the mainstream Eclipse projects! We hope to see more industry players to contribute to Eclipse in the future.

Acceleo

By Jonathan Musset, 2006-04-25
Acceleo is a pragmatic implementation of the Object Management Group (OMG) MOF Model to Text Language (MTL) standard. You do not need to be an expert to start using the plug-ins and create your first code generator : using the provided example projects and the powerful completion feature of the Acceleo editor, it is very easy to get started and understand the basic principles. Acceleo is the result of several man-years of R&D started in the French company Obeo. Junction between the OMG MTL standard, its team's experience with industrial code generation and the latest research advances into the M2T field, it offers outstanding advantages : High ability to customize, Interoperability, Easy kick off, Traceability Management, and many more!

Acceleo Review, 
by Adelino, 2006-05-21
After doing the quick start tutorial found on the Acceleo web site, I am very impressed by
the simplicity and quality of this plug-in. Acceleo allows with a few clicks to generate code 
from an EMF model using one or more JET-like templates.

Dynamic JET Generator

By Joel Cheuoua, 2004-12-10
This is an Eclipse plugin, based on EMF and JET templates, whose goal is to ease the process of automating the code generation process. Using Merlin JET Generator, you'll be able not only to dynamically generate code from your EMF Genmodel, but also yo can have a better control on the generation thanks to a customizable mapping capability between the JET templates and any Genmodel elements

Dynamic JET Generator Review, by Ed Merks, 2005-06-01
I highly recommend the JET editor if you are doing editing of JET templates. It's cool!


Great .jet editor, by J366rg von Frantzius, 2005-04-06
The included .jet editor has very good syntax highlighting and some code completion, better 
than JETEditor. Works with Eclipse 3.1 M5 (0.4.6 unfortunately is broken with 3.1 M6).

Emfatic

By Chris Daly, 2004-11-10
Emfatic is a language for representing EMF Ecore models in a simple textual form.

There are currently several different ways to construct and modify EMF Ecore models, including annotated Java, XML Schema, Unified Modeling Language (UML) tools, and the EMF model editor. The advantage of Emfatic is that it represents an entire Ecore model in a single source file and it uses a Java-like syntax familiar to many programmers.

Emfatic comprises several Eclipse plug-ins, which include an editor and a parser for the language. The Eclipse plug-ins add actions that allow Emfatic source code to be compiled into an Ecore model and also allow Ecore models to be decompiled into Emfatic source code.

Emfatic Review, by Felix Leipold, 2006-06-12
Emfatic is a nice and clear way to express emf meta models. 
It's way less cluttered than annotated interfaces. I'd love to see it in the 
standard emf distribution, perhaps with autobuild emf->ecore.

Notification Gatherer

By Constantine A Plotnikov (on behalf of IBM ATS), 2004-10-07
The Notification Gatherer component is a simple utility component that automates listening to events that happen in EMF object graph. Such code usually is not very complex, but it is quite error prone because a lot of small things should be done in a lot of places. So, from our experience, the component enhances clarity of the code and reduces number of bugs. The component is a reimplementation of the idea that was previously implemented in NSMDF and NSUML open source projects. These projects have an idea that is similar to EMF one, but their APIs significantly differ from EMF API. The plug-in is submitted as patch to EMF team. URL points to corresponding RFE.

Extended EMF Reflective Editor (Exeed)

By Dimitrios Kolovos, 2006-14-02
Exeed is a tree-based EMF model editor for editing models of arbitrary ECore metamodels. It has been implemented on top of the built-in reflective EMF editor and provides features such as customizable labels and icons for model elements both in the tree view and in the properties view. To implement customized editors using the built-in EMF tools, one needs to generate one editor for each ECore metamodel and then customize the generated code. By contrast, in Exeed customization is achieved using specific EAnnotations in the ECore metamodel itself and thus, it is not required to generate and customize one editor for every ECore metamodel. Exeed has been developed in the context of the Epsilon GMT component and is open-source software.

GMF Wizards/Macros

By Dimitrios Kolovos, 2007-14-09

This extension enables users to write and execute wizards/macros that automate complex modelling tasks in GMF editors. The extension has been implemented atop GMF and thus, it works with existing GMF-based editors (e.g. the ECore and UML2 editors) without needing to customize/re-generate them. Wizards are defined using an OCL-based task-specific imperative language (Epsilon Wizard Language) which is a part of the Epsilon GMT component and provide support for user input and integration with the GMF editing stack to enable users undo/redo the effects of wizards on the edited models.

Groovy EMF Builder

By Joern Dinkla, 2007-28-11

The Groovy programming language allows the creation of domain specific languages with its "BuilderSupport" class. This is used by EMFBuilder to create a language defined by an Ecore EFactory. Because UML2 uses EMF, UML2 models can be created using the EMFBuilder, too.

This allows a direct representation of the model in the Groovy language to programmatically create or process Ecore/EMF models.

GenGMF

By Enrico Schnepel, 2009-07-05

GenGMF is a GMF model generator. It allows the easy creation of GMF based editors. Like in GMF the editor in described in an editor model. Interactive wizards support the iterative construction of the complete model. The common layout of a group of figures is modeled in a template which could be instantiated for several meta model elements. Instantiation means that you could vary e.g. the background color of the figure without modeling a new figure like in GMF.

EuGENia

By Dimitris Kolovos, 2009-10-18

EuGENia is a tool that automatically generates the .gmfgraph, .gmftool and .gmfmap models needed to implement a GMF editor from a single annotated Ecore metamodel. EuGENia provides high-level annotations that shield you from the complexity of GMF and lowers the entrance barrier for creating your first GMF editor. While EuGENia is very useful for getting started with GMF, it doesn't stop there and can be used all the way to the final polished version of your editor.

rCOS Modeler

By Volker Stolz, March 2011.

The rCOS Modeler supports component-based model driven software development using the rCOS (Refinement of Component and Object Systems) method. It provides an UML-like multi-view and multi-notational modeling and a design platform with the ability to add plug-ins.

The tool supports the rCOS method in model construction, analysis, verification and correctness preservable transformations; and it generate verifiable code from design models.

The special features of the tool include:

In the requirements phase, it facilitates both the development process and the persistence of formal verification artifacts in the model: a use case is specified as a rCOS contracts of a components in multiple views, including a sequence diagram for the interaction protocol between the actors and the component, a state diagram for the reactive behaviour of the component, the UTP specification of the designs of the methods provided by the component, and a class diagram for definitions of the objects and data types.

In the design phase, use case components are designed by model transformations implementing proved OO refinement rules and design patterns, and then decomposed and composed into a component-based model of a logical design architecture.

Consistency of the different views of the requirements models and interface compatibilities can be checked by using model checking tools like FDR.

It supports the generation of skeletons Java sourcecode out of the whole design which results in an executable prototype.

The tool is implemented on top of the Eclipse platform using a UML profile, ensuring compatibility with other UML-based software engineering tools.

Obeo Designer

By Freddy Allilaire, March 2012.

Obeo Designer is an innovative solution to create and customize graphicals modelers and MDA studios. Obeo Designer provides a settings tool to create Domain Specific Modeling:

choose if you want to use your DSL, UML, BPMN or any other standard to store your models
define what will be displayed, the graphical aspects, tool palettes and their associated behaviors, ...
assemble these various representations in "viewpoints" dedicated for users actions (performance analysis, component design, policy control, ...)
Add code generators, model transformations and validators

Obeo Designer is based on GMF, but it simplifies the creation of new designers with an interpreted engine. You don't need anymore to be an Eclipse expert to create your own modeling environment and your own diagrams.

Main customisable parts of Obeo Designer are:

Choose of serialised format for your models (EMF)
Viewpoint customisation (dynamic GMF)
Code generation (Acceleo)
Models transformation(ATL)
Code / models traceability and synchronisation (Obeo Traceability)
Collaborative work (CDO and EMF Compare)

UML Designer

By Freddy Allilaire, March 2012.

UML Designer provides a set of common diagrams to work with UML 2.1 models. The intent is to provide an easy way to make the transition from UML to domain specific modelling. This way users can continue to manipulate legacy UML models and start working with DSL. Users can even re-use the provided representations and work in a total transparence on both UML and DSL models at the same time. This product is not yet compatible with Eclipse Indigo. This module used the standard UML2 metamodel provided by Eclipse Foundation and it implements the following generic UML diagrams:

Package Hierarchy
Class Diagam
Component Diagram
Object Diagram
Composite Structure
Use Case Diagram
Activity Diagram
State Machine
Sequence Diagram

EMF Eclipse Forms Editor

By Steve Blass, 2004-10-04
This example demonstrates how to convert a generated EMF editor to an Eclipse Forms based editor by changing the generated editor to extend FormEditor rather than MultipageEditorPart and using addPages() rather than createPages(). In particular this example implements Master/Details form editing of the libary model presented in the EMF overview documentation.
