The STEP Modular Architecture

The first Technical Note in this series [1] introduced the international standard ISO 10303, informally known as STEP (STandard for the Exchange of Product model data). Subsequent Technical Notes discussed various issues faced by users of STEP and how the ISO TC184/SC4 committee is addressing these issues. This paper presents the current move to modularize the STEP application protocol architecture. This paper describes the initial STEP architecture, requirements for improvements to the architecture, features of the new modular architecture, status and issues. Background STEP (STandard for the Exchange of Product model data, formally known as ISO 10303) is an international standard designed to enable the exchange of product data between heterogeneous computer systems used throughout the product life cycle. STEP is being developed under the leadership of ISO TC 184/SC4, the ISO sub-committee responsible for data exchange standards in the area of industrial and manufacturing application...
