Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 57: Integrated generic resource: Persistent identification of elements in procedural shape modelling. This HTML product description covers the ISO 10303-57:2018 international standard as published by ISO and available in PDF format (Edition 1, October 2018).

Abstract

ISO 10303-57:2018 specifies the integrated resource constructs used for the persistent identification of explicit model elements in procedural shape modelling. It defines standardized representations and data constructs intended to support persistent identifiers for geometry and model elements so they can be referenced, tracked and re-used across systems and over time.

Scope

ISO 10303-57:2018 provides the integrated generic resource definitions required to represent and persistently identify elements created by procedural shape modelling techniques. The scope covers data constructs, entity definitions and identification mechanisms that enable consistent identification and referencing of model elements across STEP-based data exchanges and implementations. The resource is intended to be used by higher-level application protocols and implementation modules that require stable persistent identifiers for geometry and procedural constructs.

Key topics and requirements

• Definitions of data constructs and entities for persistent identification of procedural shape model elements.
• Standardized representation of persistent identifiers so elements can be referenced across files, systems and revisions.
• Integration points for using the resource within the broader ISO 10303 (STEP) family and application protocols.
• Requirements that support traceability, long-term archival, and interoperability of procedural geometry references.
• Conformance expectations for implementers using STEP EXPRESS schemas and implementation methods.

Typical use and users

Primary users include CAD/CAM/CAE software developers, systems integrators, tool vendors, digital-archiving practitioners, and standards implementers who need stable, interoperable identifiers for elements created by procedural modelling workflows. The resource is commonly used where STEP-based data exchange, long-term model archival, and cross-tool traceability of geometry are required. Implementation and verification teams working on STEP application protocols and modules will also use this part when persistent IDs are needed.

Related standards

ISO 10303-57 is one part of the ISO 10303 (STEP) family of standards. It is an Integrated Resource (IR) and is related to other IR parts falling in the 41–62 range, as well as to various Application Protocols (APs) that consume IR constructs. For broader context on STEP structure and related parts (APs, modules and resources), consult the general ISO 10303 family descriptions.

FAQ

Q: What is this standard?

A: ISO 10303-57:2018 is an Integrated Generic Resource in the ISO 10303 (STEP) family that specifies constructs for persistent identification of elements in procedural shape modelling.

Q: What does it cover?

A: It defines data constructs, entity definitions and identification mechanisms to allow stable, persistent references to explicit model elements produced by procedural modelling methods, enabling traceability and interoperability across systems.

Q: Who typically uses it?

A: CAD/CAM/CAE developers, implementers of STEP application protocols and modules, systems integrators, and organizations requiring long-term archival and cross-system traceability of procedural geometry.

Q: Is it current or superseded?

A: The edition published in October 2018 (Edition 1) was reviewed and confirmed in 2024 and therefore remains current as of that confirmation. Implementers should check ISO for future reviews or revisions.

Q: Is it part of a series?

A: Yes — it is part of the ISO 10303 (STEP) series. ISO 10303 is a large family of parts (IRs, APs, modules and implementation methods) covering product data representation and exchange; ISO 10303-57 is one integrated resource within that family.

Q: What are the key keywords?

A: Persistent identification, procedural shape modelling, STEP, ISO 10303, integrated resource, geometry identifiers, model element IDs, interoperability.
