Overview
EN IEC 61360-7:2026 – Standard Data Element Types with Associated Classification Scheme – Part 7: Data Dictionary of Cross-Domain Concepts is an international standard developed by the European Committee for Electrotechnical Standardization (CLC) in alignment with the International Electrotechnical Commission (IEC). This standard specifies a comprehensive data dictionary domain, "IEC 61360-7 – General items," focusing on cross-domain concepts that can be applied to various electrical engineering, electronics, and related domains.
As a horizontal publication, EN IEC 61360-7:2026 provides a harmonized framework for defining, managing, and exchanging standardized data elements-such as classes and properties-enabling interoperability across sectors. The data dictionary is structured for machine-sensible integration, ensuring consistent terminology and semantic clarity in industrial data exchange.
The official data dictionary is maintained and made available through the IEC Common Data Dictionary (IEC CDD) at https://cdd.iec.ch.
Key Topics
- Cross-Domain Data Dictionary: The standard introduces a domain for general or cross-domain items, supporting cases where standardized classifications are needed across industries.
- Generic Concepts & Structures: Covers generic classes and properties that serve as building blocks for interoperable data element definitions, including classes for features, qualifiers, and operational states.
- Identification with IRDI: All dictionary elements are uniquely identified by International Registration Data Identifiers (IRDI), supporting traceability and machine-readability.
- Qualifier Properties: Includes qualifiers like applicability, value origin, processing, lifecycle, operational state, value quality, and time stamps, which help contextualize data.
- Standardized Terminologies: Ensures uniform interpretation and facilitates mapping between different domain-specific vocabularies and ontologies.
- Maintenance and Extension: The data dictionary is maintained in the IEC CDD, allowing for continuous updating, extension, and harmonization within the global standards community.
Applications
EN IEC 61360-7:2026 plays a vital role in several practical applications:
- Industrial Automation & Integration: Supports seamless exchange of technical data between automation systems, enhancing efficiency and reducing misinterpretation.
- Product Lifecycle Management (PLM): Provides a standardized base for defining product features and properties throughout design, operation, and maintenance phases.
- Digital Engineering & Twins: Enables clear and interoperable data definition in digital twin models, supporting cross-domain collaboration and accurate simulation.
- Supply Chain Data Exchange: Facilitates communication between suppliers, manufacturers, and integrators by standardizing data representation and retrieval.
- Regulatory Compliance & Auditing: Eases the creation of documentation compliant with international requirements, supporting audits and certifications.
- Data Quality & Consistency: Improves data governance by standardizing item descriptions, qualifiers, and features, ensuring high data quality and minimizing semantic ambiguities.
