The aim of this paper is a brief introduction to MDA technology and a summary / comparison to the approachments to MDA of AndroMDA and Acceleo, intending to be a practical and understandable summary Introduction Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. It was launched by the Object Management Group (OMG) in 2001 The Model-Driven Architecture approach defines system functionality using a platform-independent model (PIM) using an appropriate domain-specific language (DSL). One of the main aims of the MDA is to separate design from architecture. As the concepts and technologies used to realize designs and the concepts and technologies used to realize architectures have changed at their own pace, decoupling them allows system developers to choose from the best and most fitting in both domains. The design addresses the functional (use case) requirements while architecture provides the infrastructure through which non-functional requirements like scalability, reliability and performance are realized. MDA envisages that the platform independent model (PIM), which represents a conceptual design realizing the functional requirements, will survive changes in realization technologies and software architectures.

"I'm with Politecnico di Milano, Italy, researching on the application of model driven development (MDE/MDD/MDA = MD*) techniques to all the software field, including: web engineering and modeling of web applications (WebML, WebRatio), multimedia & multidomain search engines (Search Computing), business processes (BPMN), and web services."

" I am Johan den Haan, working for Mendix as CTO. This blog is personal, all opinions are mine and should be taken with a pinch of salt. I write about topics in the field of enterprise architecture and software engineering, like SOA, SOBA, MDE, MDA, MDD, DSL, etc. Johan den Haan on Twitter "

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.

Legacy systems embrace a large number of technologies, making the development of tools to cope with legacy systems evolution a tedious and time consuming task. As modernization projects face with both technologies combination and various modernization situations, model-driven approaches and tools offer the requisite abstraction level to build up mature and flexible modernization solutions. MoDisco provides an extensible framework to develop model-driven tools to support use-cases of existing software modernization :

The Fornax-Platform is a development platform for tools related to the Model-Driven-Software-Development - MDSD. In this context tools are cartridges, transforms, ready-to-use generators or simple enhancements to make it easier to work in a MDSD environment. Another approach is to provide Howto's and tutorials that simplify the undestanding of MDSD. The Fornax-Platform provides infrastructure and tools to simplify the management and the development of such components and tools. It is independent from companies in this area of software development.

"The Eclipse Modeling Project is one of the most active projects within the Eclipse community. Ed Merks will give a quick overview of the Modeling projects in Helios. Then Cedric Brun will demo Acceleo and Sebastian Zarnekow will show Xtext. This presentation was recorded as part of the Helios In Action virtual conference: eclipse.org/​helios/​heliosinaction.php. Presented by Ed Merks, Cedric Brun of Obeo and Sebastian Zarnekow of itemis "

"The Eclipse Modeling Project focuses on the evolution and promotion of model-based development technologies within the Eclipse community by providing a unified set of modeling frameworks, tooling, and standards implementations."

 As TOPCASED project leader I want to assess the usage of ours Tools in Academic and industrial projects. This assessment will help us and you to assure credibility of the Topcased projects and tools and then to insure their durability.  To do this "state of the art" could you give me back your usage of  TOPCASED Tools : which tool, for which kind of projects (evaluation, industrial, research) and all information you are able to give to us ? Specially for academics could you give me information about the usage of our tools in engineers trainees or thesis : which cursus at which level, number of student already trained, subject of thesis.  If you need some confidentiality on your information, tell me that and I will remains it for my own.   Thanks to send your Topcased usage returns to patrick.farail at airbus dot com  Thanks a lot to help us on this work I will give you back this results by mail.   Patrick Farail from Airbus TOPCASED Project leader 

Emfatic is a text editor supporting navigation, editing, and conversion of Ecore models, using a compact and human-readable syntax similar to Java. The EPLed Emfatic now hosted at EMFT extends the Feb 2005 alphaworks release with support for EMF Generics, folding, "red squigglies", an EMF Type Hierarchy, hyperlinks, AutoEdits, and the possibility to define templates to speed up document creation, among other usability features. The best way to gain hands-on experience with Emfatic is to right-click on any .ecore file and choose Generate Emfatic source, a similar converter works in the opposite direction. Online help is also available. Emfatic itself builds upon Gymnast, a framework for jumpstarting text editors for custom Domain Specific Languages. Documentation on how to extend Emfatic, as well as on using Gymnast, can be found in this technical report.

Mod4j (Modeling for Java) is an open source DSL-based environment for developing administrative enterprise applications. It uses a collection of DSL's to model different parts of the architecture, combined with manually written code. Currently Mod4j consists of four DSLs: the Business Domain DSL, Service DSL, Data Contract DSL and Presentation DSL. The modeling environment is seamlessly integrated into the Eclipse IDE which gives the developers one environment where they can easily switch back- and forth between models and code. The different DSL?s used in Mod4j can be used independently, but if they are used in collaboration they will be fully validated with each other. Apart from integration in the Eclipse IDE, Mod4j also supports the use of Maven. That is, using the DSL models as the source, the complete code generation process can be run automatically on a build server without the need for Eclipse. The Mod4j DSLs and the corresponding code generators are based on a reference architecture. This allows developers to model various aspects of the application and generate code that strictly follows this reference architecture. The reference architecture is described in a separate document. For a good understanding of the generated code it is useful to read this document.

Xtext - Language Development Framework With Xtext you can easily create your own programming languages and domain-specific languages (DSLs). The framework supports the development of language infrastructures including compilers and interpreters as well as full blown Eclipse-based IDE integration. While Xtext equips you with a set of sensible defaults, you can tweak every single aspect of your language with Xtext's powerful APIs. A comprehensive documentation as well as the vivid community will help you getting started in no time. And if that is not enough you can buy trainings, consulting or support contracts delivered directly by the committers.

modeling workflow engine (MWE) supports orchestration of different Eclipse modeling components to be executed within Eclipse as well as standalone. Based on a dependency injection framework, one can simply configure and wire up 'workflows' using a declarative XML-based language. The project provides the runtime used to execute workflows as well as the IDE tooling used to edit, start and debug them.

COPE, a tool based on EMF that eases the migration of models in response to an evolving metamodel. COPE explicitly records the history of the metamodel as a sequence of changes and allows to attach information of how to migrate models (which is referred to as coupled evolution). The attached information can be used to automatically migrate models to the new version of the metamodel. COPE even goes one step further and allows to reuse combinations of metamodel adaptation and model migration steps across metamodels.
