ISO 13584-25:2004

Overview

ISO 13584-25:2004 - part of the ISO 13584 series on parts libraries - defines a logical model of supplier libraries that supports aggregate values and explicit content using the EXPRESS modeling language. The standard provides generic EXPRESS resource constructs to represent aggregate data types and values, and an integrated EXPRESS information model for exchanging supplier libraries. It enables supplier libraries to contain definitions, part families, representation categories and explicit instance sets, facilitating structured parts library exchange in industrial automation and PLM environments.

Key Topics

• EXPRESS-based resource constructs for modeling aggregate data types and aggregate values (aligned with ISO 10303-11 definitions).
• Integrated information model combining constructs from ISO 13584 parts and ISO 10303 to form a single schema for supplier libraries.
• Representation categories and explicit content: libraries can define representation categories, dictionary elements, and explicit sets of permitted instances (explicit content models).
• Assembled parts modeling: constructs for representing assembled parts that may contain an unlimited number of constituent components.
• Data exchange enabling: designed to be used with view exchange protocols to permit exchange of one or several representation categories for parts defined in a parts library.
• Scope boundaries: explicitly excludes representation of expressions and variables, implicit instance-set descriptions via constraints, and specification of a software system to manage supplier libraries.

Applications

ISO 13584-25:2004 is intended for organizations that need standardized, machine-readable representations of supplier part libraries where properties can be aggregate-structured or where classes have explicitly enumerated instances. Typical applications include:

• Exchanging supplier parts and catalog data between CAD/PDM/PLM systems.
• Defining supplier libraries that include complex aggregated property values (lists, arrays, sets).
• Integrating part families and multi-component assemblies into data exchange workflows.
• Implementing view-exchange scenarios to share selected representation categories of parts.

Who uses this standard

• Manufacturers and suppliers preparing structured digital catalogs.
• System integrators and OEMs needing consistent parts data for automation systems.
• PLM/PDM and CAD software vendors implementing parts library import/export and data exchange features.
• Data modelers and standards specialists working with EXPRESS schemas and ISO 10303 interoperability.

Related Standards

• ISO 13584 (other parts) - Parts library family of standards.
• ISO 10303-11 - EXPRESS language and aggregate data type definitions (referenced by ISO 13584-25).

Using ISO 13584-25:2004 supports interoperable parts library exchange, precise modeling of aggregate property values, and clearer supplier–consumer data flows in industrial automation and product lifecycle management.
