ISO/IEC 11179-30:2023

Overview

ISO/IEC 11179-30:2023 - Information technology - Metadata registries (MDR) - Part 30: Basic attributes of metadata defines a minimal, standardized set of basic attributes needed to describe metadata where a full ISO/IEC 11179-3 metadata registry is not appropriate. Published in 2023, this part of the ISO/IEC 11179 series provides a simplified set of metadata descriptors suitable for use in other International Standards, data dictionaries, and lightweight metadata specifications. It supports consistent interpretation, interchange and referencing of metadata across systems and documents.

Key topics and requirements

• Defines the notion of basic attributes for metadata items and provides terms and definitions for core concepts such as data element, data element concept, conceptual domain, value domain, permissible value, and value meaning.
• Specifies common attribute categories used to describe metadata items, including:
  • Identifying attributes (unique identifiers)
  • Naming attributes (labels and preferred names)
  • Definitional attributes (definitions and explanatory notes)
  • Administrative attributes (status, versioning, provenance)
  • Relational attributes (links between metadata items)
• Lists attributes specific to different metadata objects: data element concepts, data elements, conceptual domains, value domains, permissible values, and value meanings.
• Includes a conformance framework describing degrees of conformance (e.g., strictly conforming implementations, conforming implementations) and requires an Implementation Conformance Statement (ICS) for declared conformance.
• No normative references are required for this document, emphasizing its role as a lightweight attribute specification.

Applications and who uses it

ISO/IEC 11179-30:2023 is practical for organizations and professionals who need standardized metadata without implementing a full metadata registry:

• Standards developers embedding metadata requirements in other International Standards
• Data architects and data modelers creating consistent data element specifications
• Data stewards and governance teams preparing data dictionaries and catalogs
• System integrators and software developers implementing interoperable data exchange formats, code lists or lightweight MDRs
• Government agencies and regulated industries standardizing national or sectoral data collections

Benefits include improved metadata consistency, clearer data definitions, easier data interchange, and streamlined documentation for compliance and interoperability.
