Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 43: Integrated generic resource: Representation structures. This part of ISO 10303 (STEP) defines the resource constructs used to group product-data elements into collections and contexts for the purpose of representing product-related information.

Abstract

ISO 10303-43:2000 specifies representation-structure constructs (representation items, contexts and grouping mechanisms) that allow elements of product data to be combined, associated and reused to describe aspects of products across CAD/CAM/PDM environments. It provides the conceptual building blocks used by STEP application protocols and integrated resources to express how product information is presented and organized.

Scope

This part of ISO 10303 defines the resource-level constructs for representation structures: the contexts in which representation items are combined, the element types used to describe presentation and structure, the associations between elements (including definitional and compositional relationships), and the means to group elements into representations that can be reused across different views or application protocols. It is intended for use when describing properties and representational aspects of products within STEP-compliant data exchanges.

Key topics and requirements

• Definition of representation constructs (representation items and contexts) used to model presentation-oriented data.
• Rules for grouping and associating representation elements into collections and representations used across product descriptions.
• Specification of relationships between representation elements (including one element defining or referencing another).
• Expressing presentation contexts so that similar representations can be applied to multiple product instances or views.
• Integration with other ISO 10303 integrated generic resources and with application protocols that consume representation structures.

Typical use and users

Used by implementers and integrators of STEP-based CAD/CAM/PDM systems, software vendors producing STEP import/export modules, systems engineers defining data-exchange profiles, and standards authors creating or maintaining application protocols that rely on representation data. Typical use cases include exchanging presentation information (views, pictorial representations, assemblies of representational elements), creating neutral archives of product representations, and enabling downstream systems to interpret or render product views consistently.

Related standards

Part of the ISO 10303 (STEP) family. Commonly referenced or paired parts include ISO 10303-1 (overview and principles), Parts 11 and 21 (description and implementation methods such as EXPRESS and STEP-File), other integrated generic resources in the 40–62 range (for structure, geometry and presentation), and higher-level application protocols (for example AP203/AP214/AP242) that use representation constructs. Later revisions of Part 43 and adjacent IR/AP parts (releases up to 2022) provide the current normative references.

FAQ

Q: What is this standard?

A: ISO 10303-43:2000 is Part 43 of the ISO 10303 family (STEP), titled "Integrated generic resource: Representation structures", which defines constructs for organizing and grouping representation (presentation) elements of product data.

Q: What does it cover?

A: It covers resource constructs for representation structures — contexts, representation items, grouping and association rules — used to describe how product information is presented and organized for exchange and reuse across systems.

Q: Who typically uses it?

A: CAD/CAM/PDM software developers, integrators, systems engineers, and standards authors who need a neutral, standardized way to represent presentation and view-related product data in STEP exchanges.

Q: Is it current or superseded?

A: The 2000 edition (Edition 2) has been withdrawn. Part 43 has been revised in subsequent editions; the active published version of Part 43 (as recorded by ISO) is the 2022 edition (ISO 10303-43:2022). Users should prefer the latest published edition for current implementations.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 (STEP) family of standards, which is organized into description methods, implementation methods, integrated generic resources (including Part 43), application protocols, and other modules.

Q: What are the key keywords?

A: STEP, ISO 10303, representation structures, representation items, presentation context, integrated generic resource, product data exchange, CAD interoperability.
