Dassault Systèmes Unveils V5 SOA Strategy

Open architecture for collaborative online PLM services

Paris, France, June 22, 2006 – Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced its V5 SOA (Service Oriented Architecture) strategy. This strategy demonstrates DS’ commitment to extend the benefits of PLM solutions to new markets and new types of users and communities. V5 SOA is the cornerstone for DS and its partners to deliver fully collaborative PLM services on demand.

“I am delighted that DS fully endorses the SOA strategy and standards for its applications and extends it to match customers’ PLM needs,” said Robert LeBlanc, General Manager, Websphere, IBM. “Together with DS, we will service our customers and partners with the unique value of our combined complete PLM solutions to collaborate and innovate.”

“With our V5 SOA strategy, DS extends current CAA V5 architecture with best in class web technologies and introduces the unique power of 3D collaborative applications for networked innovation,” explains Dominique Florack, executive vice president, Strategy, R&D, Dassault Systèmes. “DS demonstrates once again its commitment to secure and leverage customers’ investments while continuously delivering breakthrough applications and services to speed up and extend the PLM business transformation.”

“V5 SOA increases our ability to develop next-generation PLM solutions and solve the challenges at the core of our customers’ businesses,” says Yoshikazu Niwa, executive corporate officer, Nihon Unisys Solutions Ltd. “SOA architecture allows us to rapidly integrate our solutions based on an existing application framework, with a unified user interface, bringing added flexibility to the supply chain. It will drive innovation and ensure that our customers remain competitive.”

V5 SOA is the technical foundation for DS’ PLM brands and partners’ solutions moving forward. It bridges the gap between PLM solutions and existing enterprise middleware, by providing services in five key domains:

  V5 SOA collaborative user experience
  V5 SOA business process modeling and execution
  V5 SOA IP modeling, integration and management
  V5 SOA Enterprise foundations (search, collaboration…)
  V5 SOA openness (web services, 3DXML, …)

DS will leverage its strategic technological partnerships with IBM and Microsoft to optimize V5 SOA on their respective platforms.

The V5 SOA strategy will be unveiled at the annual CAA V5 DEVCON Conference in Paris on June 27-28, 2006 where customers and partners can network and learn the latest information on the CAA V5 development platform for PLM solutions. Complete information on registering to attend DEVCON 2006 and a full program of events can be found at www.3ds.com/devcon
