ISO 13584-501:2007

Overview

ISO 13584-501:2007 - "Industrial automation systems and integration - Parts library - Part 501: Reference dictionary for measuring instruments - Registration procedure" defines the requirements and processes for an ISO-registered reference dictionary for measuring instruments. The standard specifies how to represent measuring-instrument classes, descriptive properties (data element types) and domains of values as computer-interpretable dictionary entries. It also establishes the role and required behaviour of a registration authority responsible for developing, validating, maintaining and distributing the reference dictionary. Covered instruments include environmental and laboratory measuring instruments.

Key topics and technical requirements

• Reference dictionary structure: each dictionary entry (class, property or domain of values) has a human-readable definition and a computer-sensible unique identifier to allow unambiguous referencing.
• Ontology representation: entries implement ontologies for the measuring-instruments domain; entries are instances of EXPRESS entity data types from the common dictionary schema.
• Classification principles: rules for hierarchical classification (principal identification layers, domains, functions, principles) and auxiliary classifications to ensure consistent indexing.
• Registration authority processes: organization structure, roles (technical committee, validation committee, secretary), decision rules, registration workflow and timeframes for initial registration and updates.
• Computer-sensible description and distribution: requirements for information models, conformance classes, external files, language usage for text attributes, control of intermediate/formal releases, and distribution mechanisms.
• Versioning and maintenance: rules for version and revision numbering, formal release identification, and long-term maintenance procedures.
• Normative annexes: include templates and formats such as information object registration, physical dictionary file layout, class/property definitions and application forms.

Practical applications and users

ISO 13584-501 is used to achieve consistent, interoperable description and exchange of measuring-instrument data across systems. Typical users:

• Manufacturers and suppliers of measuring instruments (environmental and laboratory)
• Metrology and testing laboratories
• Software vendors (PLM, PDM, parts library, CAD) implementing parts libraries and data exchange
• Systems integrators and automation engineers requiring standardized device descriptions
• Procurement, regulatory and compliance teams needing unambiguous identification and properties

Benefits include improved data interoperability, reliable referencing of instrument properties and domains of values, and streamlined cataloguing and exchange of parts and instrumentation data.
