Les recherches relatives à la modélisation pourraient bien connaître une grande avancée dans les années à venir. En effet, un groupe d’ingénieurs est actuellement en cours d’étude pour mettre en place l’interchangeabilité des modèles. Ce groupe de travail qui porte le nom de MIWG (new Model Interchange Working Group) aura ainsi la lourde mission de permettre les échanges et les transferts de modèles qui suivent déjà les normes de langages de modélisation unifiées, l’UML, et qui ont été définies par l’OMG ou Object Management Group. Comme les modèles sont à la base de toute programmation informatique, il est certain que cette recherche revêt une grande importance pour l’avenir de l’informatique. En effet, toute programmation est conçue sur la base d’une analyse logique qui est commune à tous les programmeurs. Par contre lors de la modélisation, chaque programmeur a sa façon de procéder, ce qui a auparavant mené à l’existence d’une multitude de modèles aussi différents les uns des autres mais qui ont tous aboutis à un résultat final utilisable par tous. C’est ainsi que l’OMG a vu le jour en 1989 pour établir des normes de modélisation et ce consortium continue encore dans sa lancée en initiant ce nouveau projet. Ce groupe de travail est alors constitué d’ingénieurs travaillant pour des grands noms de l’informatique comme IBM ou Adaptive d’une part et d’autre part ceux qui sont employés par le Département Architecture Framework du Ministère de la Défense britannique et américaine. Cette équipe se réunit chaque lundi avec une mission bien définie pour une cause bien définie.
La mission du MIWG
La mission de ce groupe de travail consiste à trouver des solutions pour permettre les échanges et les transferts des modèles utilisés par les diverses branches des départements de défense britannique et américaine, ainsi que ceux utilisés par les multitudes d’entreprises et de sous-traitant travaillant de près avec eux, le but étant ainsi de faire avancer beaucoup plus vite le travail commun de ces diverses entités car en ayant la possibilité d’échanger et de transférer les modèles, elles pourront tout de suite adapter et recréer ces modèles selon leurs domaines respectifs tout en respectant les normes déjà établies. Cette étude aboutira ainsi au final à la mise en place d’une nouvelle norme d’échanges et de transfert de modèles. Certes les Départements de Défense britannique et américaine seront les premiers bénéficiaires des résultats obtenus par ce groupe de travail, mais il est certain que les autres domaines vont aussi en profiter dans les années à venir une fois que cette norme sera rodée.

OMG Announces Model Interchange Working Group Working group has successfully completed first test case for UML®-based modeling tool interoperability
Needham, MA, USA - July 8, 2009 - OMG™ members have formed the Model Interchange Working Group (MIWG) to demonstrate and facilitate interoperability between UML®-based modeling tools. The group's initial focus is on model interchange between UML®, OMG SysML™, and Unified Profile for DoDAF and MODAF (UPDM) -capable tools. MIWG comprises end users, tool vendors and experts in the UML and XMI® standards.
The MIWG's approach is to create an export of the same UML model from each participating vendor's tool and then import those models into each other's tool. The XML Metadata Interchange (XMI) format, the OMG standard for exchanging models, is used by the MIWG to transfer the model data among the participating tools. This approach will be applied across a number of test cases representing different types of models. The first test case, representing a UML Class Model, has been successfully completed, and is available on the group's Wiki page at http://www.omgwiki.org/model-interchange. Subsequent test cases will also be posted to the Wiki.
"End-users, large and small, value the ability to seamlessly move models between the various tools they use. We felt it was imperative that we could prove that tools that are built on OMG standards are in fact interoperable," said Richard Mark Soley, Ph.D., chairman and CEO, OMG. "Studies have shown that UML is in use in more than 70% of software-development organizations, along with other profiles such as SysML and UPDM that have extended UML for specific domains. As usage of these standards increase, it becomes even more critical that model interoperability is ensured."
"Model interchange is essential to achieve integration among a broad range of systems and software design and analysis tools," said Sanford Friedenthal, from Lockheed Martin and chair of the MIWG. "End users are beginning to expect this capability in their tools, and the standards have matured to a level that this is now achievable. In addition, the vendor participants in the MIWG are working very hard to deliver this capability. They have found this interchange process to provide an efficient mechanism to enhance model interchange as indicated in their responses."
"We have found our involvement in the OMG's Model Interchange Working Group to be highly valuable," stated Hedley Apperly, VP Marketing at Artisan. "Not only did we help define the first standard test case for model interchange but we have already used it to improve Artisan Studio, resulting in real model interchange benefits for our customers. Along with the other MIWG members, we would encourage other modeling tool vendors to get involved and reap the benefits of participating."
"Based on the technology of the Objecteering UML modeling tool, SOFTEAM has set up in 2009 a new generation of modeling tool called Modelio (http://www.modeliosoft.com). Interoperability is nowadays a critical feature required by the market," said Philippe Desfray, VP for R&D, SOFTEAM. "This MIWG effort between vendors and other contributors, based on the latest generation of OMG standards using XMI, will provide effective proven modeling tool interoperability. SOFTEAM welcomes this OMG MIWG initiative, and invests efforts into this working group in order to guarantee the interoperability of the Modelio modeling tool."
"Model interchange is increasingly important to our customers' businesses, and we are pleased to be able to take an active role in this initiative," said Sridhar Iyengar, IBM Distinguished Engineer. "For a long time our development teams have worked to promote modeling standards and model interchange. This concerted effort to create and agree upon a model interchange standard will allow our customers to more effectively participate in development processes that involve multiple design teams and modeling tools."
Participating Vendors include Adaptive, Artisan, EmbeddedPlus, IBM, NoMagic, Sodius, SOFTEAM, and SPARX Systems. The US National Institute of Standards and Technology (NIST) is participating to provide a validation tool as a key enabler of this process. Model Driven Solutions (MDS) has been providing additional technical expertise and configuration management support of the modeling artifacts.
Get Involved
The MIWG is continuing to produce test cases on an incremental basis to provide extensive coverage of areas of interoperability for UML, SysML and UPDM. Any organization that wishes to participate in the MIWG is encouraged to join OMG.
