![]() The Core model Committee Draft (CD) is currently in ballot process at ISO!The 10303-4000 (Core model) ballot will end 19 March 2021. Contact your national standardisation body to download this CD and contribute by providing comments. ![]() ISO STEP Core model Technical Report available The “Core model” is an essential component of the STEP Extended Architecture. The Core model, developed in SysML, provides a set of data interoperability capabilities harmonised and shared between STEP Application Protocols (AP242, AP243 MoSSEC, AP239 PLCS).

Published in March 2020 ![]() The two phases of AP239 ed3 development:
From an administrative viewpoint, the first phase has been linked to a first ISO AP239 ed3 project, and the second phase will be associated to a second ISO AP239 ed3 project (due to the time needed to perform the harmonization work). During the AP239 ed3 workshop in Asheville, NC (USA) in March 2019, the AP239ed 3 Steering Committee has then made the decision to propose a New Work Item at ISO for the second AP239 ed3 project. This NWI will be balloted at ISO in Q1 2021. ![]() The STEP AP239 ed3 "PLCS" White Paper was submitted as an accompanying document of the related ISO New Work Item in November 2015. You can download the White Paper here. | ![]() ISO 10303-239 “Product Life Cycle Support” Edition 3 projectContext“Our product information lives for more than 50 years, and we need to understand how to manage that over time”. Enterprises today are more aware that data and information assets represent significant values, with direct influence on their financial performance and operational capabilities. Poor quality and poor management of data and information resources are recognized as major cost drivers and a significant obstacle to business performance and improvement. ISO standard 10303 STEP with its Application Protocols, Methods and Models represents a viable alternative to the current chaos of multiple, fragmented standards and proprietary data formats, and is a proven way to ensure fast, reliable data exchange between partners and suppliers using different systems. STEP supports engineering, manufacturing, electrical/electronics, architecture and product life cycle information. STEP AP 239 edition 3 project objectivesConsidering above status, and after analysis of requirements from A&D industries (ASD SSG, ASD ILS DMEWG, SAE LOGSA, LOTAR, OASIS PLCS members) and from MoDs and Defense bodies (US, UK, Swedish, Norwegian and French), it is clear to all stakeholders that a new version of STEP AP239 (named “edition 3”) is needed to secure past investment in PLCS and to answer to new business needs from Industry and from Operators. The proposed STEP AP 239 edition 3 project was formalized end of 2015 through a White Paper (ref). The main objectives of STEP AP 239 edition 3 are:
A normative XML schema is the priority – based on the core model (and related derived XSD) of the new STEP architecture, across all STEP APs.
Consistency with other standardization projectsThis standard will be consistent with the ISO 10303 STEP modular Application Protocols described in the following figure:
As illustrated in the next figure, the STEP series of standards has been designed to cover the entire life cycle of product data across all functions throughout the supply network.
The project will take also into account close coordination with other related standardization projects (e.g. LOTAR, STEP AP 242 ed2, STEP AP 209, STEP AP 210, STEP AP233, PDM-IF / Future PLCS Implementor Forum). PlanningThe project plan is described in the following figure, with a kick-off in June 2016 and a final result (AP239 ed3 International Standard) published by ISO in 2021: Call for participationDon’t miss the opportunity to build the ISO standard that will enable the future product support services, to be used from design of product support to operation!
