| ![]() The objective of this web page is to provide an overview of the ISO STEP Extended Architecture project, supported by the ASD SSG. It covers:
Goals and benefits of the STEP Extended ArchitectureThe goal of the STEP Extended Architecture project is to answer to the increasing needs of the industries, governmental agencies and PLM vendors / integrators to use a set of efficient and consistent international standards for product and process information interoperability. Several initiatives of development of PLM interoperability standards are progressing, but most of them are fragmented, either limited to a specific technical domain (e.g., requirement management, electrical harness), to a type of industries, or to a specific function (visualisation, integration/sharing). For the European Aerospace and Defence industries, with products developed with a worldwide supply chain, with a very long life (> 70 years), and a very high level of security, it is crucial to rely on ISO standards having a broad scope, capable to be enhanced and maintained through the time.

Project managed by ISO/TC 184/SC 4The status of progress and orientations of the STEP Extended Architecture” project is managed by the ISO/TC 184/SC 4 organisation. It is documented and approved via the WG 12 and WG 21 of the Subcommittee 4. Objectives of the projectThis project aims at enhancing the existing module-based STEP standard architecture, in order to deliver more benefits and easier implementation and usage by the international community.
Overview of the main related STEP standards of interest for the European A&D industriesThe current STEP architecture covers the following Application Protocols (APs), organised in 2 categories, modular and non-modular, but sharing in any case the same generic implementation constructs (“Application Resources” and “Integrated Resources”, in STEP terminology): Modular Application Protocols:
Non modular Application Protocols:
The next figure illustrates the information scope of these standards. First planned deployments of the results of the STEP Extended ArchitectureThe STEP architecture is enhanced in a phased approach, taken into account the lessons learnt from the past STEP standards implementation, and of the new business and Information Systems technology needs. The first major evolution of the STEP architecture are planned to be implemented at short term for the development of the following Application protocols:
