ISO 13584-24:2003

Overview

ISO 13584-24:2003 - Industrial automation systems and integration - Parts library - Part 24: Logical resource: Logical model of supplier library - defines a logical model and EXPRESS-based resource constructs for representing and exchanging supplier libraries (PLIB). The standard provides a set of integrated EXPRESS information models that combine constructs from other parts of ISO 13584 and ISO 10303 (STEP) into a single schema. It supports exchanging libraries made up of part-family definitions, family representations, and new representation categories, and it includes provisions for referencing external files and specifying allowed file formats.

Key topics and technical requirements

• Integrated EXPRESS information models: three LIIMs are defined to support exchange of (1) definitions of families of parts, (2) representations of families of parts, and (3) definitions of new representation categories.
• Generic EXPRESS resource constructs: reusable types and entities (instance resources, table resources, variable semantics, domain resources) used to model supplier libraries.
• Explicit vs implicit modelling: mechanisms for both explicit (set-extension) and implicit (meta-modelling / entity data type) descriptions of part families and classes.
• Two-level description & dictionary interoperability: integration with common dictionary schemas (including interoperability considerations with IEC 61360) and the BSU mechanism for referencing between schema populations.
• Library expressions and rules: strong typing of variables/expressions, property values, context-dependent properties, and a set of EXPRESS rules/functions to ensure semantic consistency.
• External file referencing and formats: provisions for supplier libraries to reference external documents/files; the standard specifies allowed formats per model, and points to the ISO 13584 view-exchange protocol parts for additional formats.
• Internet/HTTP support: guidance for representing documents within a library exchange context and remote access via HTTP.

Applications

ISO 13584-24 is practical for:

• Exchanging supplier part catalogs and digital component libraries across PLM, CAD and ERP systems
• Standardizing part-family definitions and multiple representation formats (geometry, metadata)
• Implementing supplier-neutral parts library (PLIB) solutions for procurement, BOM management, and configuration
• Enabling automated data interchange between manufacturers, suppliers and system integrators

Who should use this standard

• Component and supplier catalog managers
• PLM/CAD/ERP developers and integrators
• Software vendors implementing PLIB or STEP/EXPRESS-based data exchange
• Systems engineers and standards architects working on industrial automation interoperability

Related standards

• ISO 13584 (PLIB family of parts library standards)
• ISO 10303 (STEP - product data representation)
• IEC 61360 (common dictionary / component attributes)
• ISO 13584 view-exchange protocol parts (external file formats and views)
