ISO 13584-24:2003

Industrial automation systems and integration - Parts library - Part 24: Logical resource: Logical model of supplier library

ISO 13584-24:2003 provides generic EXPRESS resource constructs that support the description of different kinds of information about supplier libraries. It also contains a set of integrated EXPRESS information models for representing supplier libraries for the purpose of exchange. These integrated information models integrate EXPRESS resource constructs from different parts of ISO 13584 and ISO 10303 into a single schema. Three integrated EXPRESS information models are defined in ISO 13584-24:2003. They permit respectively the exchange of libraries which consist either of definitions of families of parts, representations of families of parts or definitions of new representation categories that may be provided for any family of parts. These integrated EXPRESS information models contain provisions that permit a supplier library to reference external files. For each integrated EXPRESS information model, ISO 13584-24:2003 specifies which formats are allowed for these external files. Other external file formats are defined in the view exchange protocol series of parts of ISO 13584.

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)

Keywords: ISO 13584-24, parts library, supplier library, EXPRESS, PLIB, data exchange, industrial automation, product data, STEP, ISO 10303.
