ISO 22745-20:2010

Overview

ISO 22745-20:2010 - part of the ISO 22745 series on industrial automation systems and integration - defines procedures for the maintenance of an Open Technical Dictionary (OTD). The standard specifies how organizations and consensus bodies can contribute, update and manage terminology and concepts used as master data for industrial automation and related systems. Core maintenance actions covered include registering contributor organizations, adding and updating concepts and terminology, marking terms as deleted, and merging concepts.

Key Topics

• Registration of consensus organizations authorized to contribute terminology to an OTD
• Adding new concepts together with associated terminology and descriptive metadata
• Extending existing concepts by adding new terminology or language variants
• Marking terminology as deleted to preserve history while indicating deprecation
• Merging concepts to resolve duplicates or align overlapping entries
• Governance elements typically implied by these procedures: versioning, traceability, roles and responsibilities, and change control mechanisms for master data and terminology

Applications

ISO 22745-20 is practical for any activity that depends on consistent technical vocabulary and master data across systems and organizations:

• Establishing and maintaining an open technical dictionary (OTD) for catalogs, product data and component libraries
• Improving interoperability between PLM, PIM, ERP and procurement systems by standardizing concept and term definitions
• Enabling consistent master data management (MDM) and supplier/product onboarding in industrial supply chains
• Supporting terminology committees, standards bodies and industry associations in coordinated vocabulary curation
• Helping software vendors implement standardized procedures for adding, deprecating or merging terms in terminology management tools

Who should use it

• Data governance and master data teams in manufacturing and industrial organizations
• Product and catalog managers responsible for technical metadata and part classification
• Systems integrators and software vendors building PIM/PLM/MDM solutions that handle terminology and controlled vocabularies
• Industry associations, standards committees and consensus organizations managing shared technical dictionaries

Related standards

• Other parts of the ISO 22745 series (Open Technical Dictionaries and their application to master data)
• Standards and best practices addressing master data management and data quality

ISO 22745-20:2010 is essential for organizations that need repeatable, auditable procedures for maintaining open technical dictionaries, ensuring consistent terminology, master data integrity and effective cross-system interoperability.
