Openness is important for BMW and DS Powerful: From thousands of publicly available APIs to open interoperability between V6 and other PDM, CAD, and enterprise systems, V6 is designed for openness Interoperability V6 is interoperable with CAD desktop systems through xcad adapters, with ERP and non-ds PDM applications via the X-PDM Event Bus, and via Web Services for other integrations. There also exist several alternatives for Federation of data including Exalead and Adaplets. ormation 5/10/2012 ref.: 3DS_Document_2012 3DS.COM Dassault Systèmes Confidential Info Leading: DS is leading the definition, implementation and improvement of PLM openness. (e.g., DS is a committed, well recognized and core team member of the Codex of PLM Openness (CPO) initiative). DS signed the CPO next steps ongoing. Committed to Industry Standards: DS supports global ISO standards For over 30 years, DS has relentlessly driven PLM towards an open, unified collaborative platform for our customers. Infrastructure V6 leverages industry-standard protocols such as HTTP and HTTPS, as well as existing NAS and/or SAN disk sub-systems Extensibility V6 provides a comprehensive CAA2 development environment to perform GUI enhancements, data model optimization, changing business logic and behavior, creating new applications, creating or updating integration components, and much more Interfaces V6 Web Services Infrastructure is compliant to Standards XSD, WSDL, SOAP, WS-I Standards, WS-Security (new in V6R2013), as well as wide range of APIs, Web Services for customization, automation and integration Standards V6 through its integration architecture supports a variety of standards such as STEP, IGES, FMI, AUTOSAR and JT - Dominique Florack, Senior EVP, Products, Strategy - R&D Dassault Systèmes Architecture V6 supports an n-tier layered architecture supporting industry-standard operating systems, applications servers, databases and virtualization platforms 30
