Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1: Overview and fundamental principles. This part of ISO 10303 (STEP) provides the high-level overview, architectural principles and organizational structure used across the ISO 10303 series to enable machine-readable product data representation and exchange across the product lifecycle.

Abstract

ISO 10303-1:2024 defines the scope and architectural principles of the ISO 10303 family. It describes the structure of the series (integrated resources, application modules, application interpreted constructs, application domain models, application protocols and implementation methods), introduces data specification methods such as the EXPRESS language and graphical model presentation, and outlines conformance and testing frameworks used across the STEP standard.

Scope

ISO 10303-1:2024 provides the scope statement for the ISO 10303 series as a whole and an overview of the series’ architecture and structure. It documents the characteristics and relationships of the series’ constituent sets of parts (integrated resources, modules, interpreted constructs, domain models, application protocols), introduces the data-specification approaches (notably EXPRESS and graphical model presentations), and outlines implementation methods, usage guides and conformance/testing frameworks used across STEP.

Key topics and requirements

• Overview of the ISO 10303 (STEP) family and its purpose (product data representation and exchange).
• Architectural principles for product information models and modular organization of parts (IRs, AMs, AICs, ADMs, APs, Core model).
• Descriptions of data specification methods including the EXPRESS language and graphical model representations.
• Guidance on implementation methods, usage guides and recommended practices for applying STEP parts.
• Conformance testing methodology and abstract test suites (ATS) framework used for validation of implementations.
• Scheme for identification and versioning of schemas and other information objects within the ISO 10303 series.

All items above are defined or summarized in the official part-1 text for the ISO 10303 series.

Typical use and users

Used as the overarching reference for implementers and specifiers of STEP-based data exchange: CAD/PLM software vendors, systems integrators, data interoperability teams, OEMs in aerospace/automotive/industrial machinery, standards committees, conformance/test laboratories, and archivists planning long-term product data retrieval. Part 1 is consulted when designing or mapping application protocols, implementing EXPRESS schemas, or establishing conformance/testing strategies across product data workflows.

Related standards

ISO 10303-1 is the introductory part of the ISO 10303 (STEP) family. Commonly referenced related parts include: Part 11 (EXPRESS), Part 21 (STEP-file / exchange syntax), and numerous Application Protocols such as ISO 10303-242 (AP242, Managed Model Based 3D Engineering) and earlier APs (AP203, AP214). A number of application-module and technical-specification parts (for example recent ISO/TS 10303-1001 and ISO/TS 10303-1011) extend the modular content of the series.

Keywords

ISO 10303, STEP, product data, data exchange, EXPRESS, application protocol (AP), integrated resources (IR), application module (AM), conformance testing, PLM, CAD interoperability, product lifecycle data.

FAQ

Q: What is this standard?

A: ISO 10303-1:2024 is Part 1 of the ISO 10303 family (STEP). It is the overview and fundamental-principles document that defines the architecture, structure and scope of the entire ISO 10303 product-data representation and exchange standard.

Q: What does it cover?

A: It covers the series’ scope statement, architectural principles, the relationships and characteristics of the series’ parts (IRs, AMs, AICs, ADMs, APs, core model), data-specification methods (including EXPRESS), implementation approaches, usage guides and the conformance/testing framework.

Q: Who typically uses it?

A: CAD and PLM vendors, integrators, OEM engineering and data-exchange teams, implementers of STEP application protocols, standards developers and test laboratories use Part 1 as the canonical reference when planning, developing or validating STEP-based information models and exchanges.

Q: Is it current or superseded?

A: ISO 10303-1:2024 is the current published edition (Edition 3, published in January 2024) and replaces the 2021 edition which was withdrawn. National catalogues show the 2024 publication date and the ISO record lists the edition and lifecycle status.

Q: Is it part of a series?

A: Yes — ISO 10303-1 is the introductory part of the ISO 10303 (STEP) series. The series contains many parts (EXPRESS, exchange syntaxes, application protocols and application modules) that together define how product data is modeled, exchanged and validated.

Q: What are the key keywords?

A: STEP, ISO 10303, product data, data exchange, EXPRESS, application protocol, integrated resources, application modules, PLM, CAD interoperability.
