IEC 61360-7:2024

Overview

IEC 61360-7:2024 specifies a new data dictionary domain published in the IEC Common Data Dictionary (IEC CDD): "IEC 61360-7 – General items." This horizontal publication (per IEC Guide 108) defines generic, cross-domain concepts - classes, properties and qualifiers - intended to support unambiguous data exchange across electrotechnical and related domains. The dictionary is provided in DB format and maintained in IEC CDD (https://cdd.iec.ch).

All dictionary elements are machine-identifiable using an IRDI (International Registration Data Identifier). An IRDI comprises three sections separated by the character "#":

• RI - registration authority identifier
• DI - data identifier (range CAA000 to CAZ999 reserved for this domain)
• VI - version identifier

The document is designed to improve semantic interoperability, reuse of common concepts, and consistent metadata for systems that exchange technical data.

Key Topics

• Generic concepts and structures: The data dictionary defines a domain "General items" and its generic structures (classes and assigned properties) to be used across domains.
• Library of properties and qualifiers: A set of standardized properties (property IDs CBA001–CBA008) and their attributes (preferred name, definition, source, data type) are specified. Examples include:
  • Applicability qualifier (CBA001)
  • Value origin qualifier (CBA002)
  • Value processing qualifier (CBA003)
  • Life cycle qualifier (CBA004)
  • Operational state qualifier (CBA005)
  • Value quality qualifier (CBA006)
  • Time stamp token (UTC) (CBA007)
  • Time stamp token (TAI) (CBA008)
• Identification and coding rules: IRDI structure and reserved DI ranges are defined to ensure consistent registration and versioning.
• Maintenance and governance: Further development and maintenance follow the SDB content procedure (ANNEX SK) and are published in IEC CDD.

Applications

This data dictionary is practical for organizations and projects that require:

• Cross-domain data interoperability between product, systems and services in electrotechnology and adjacent domains.
• Standardized metadata for product ontologies, configuration management, asset information models and digital twins.
• Consistent qualifiers for value provenance, applicability, lifecycle stage and time-stamping when exchanging measurement and attribute data.

Use cases include system integration, data harmonization in supply chains, standardized catalogue entries and semantic enrichment of engineering data.
