Overview
ISO/IEC 11179-3:2023 - "Information technology - Metadata registries (MDR) - Part 3: Metamodel for registry common facilities" defines a conceptual metamodel for metadata registries. It specifies the information that must be recorded in an MDR using a conceptual data model and provides a reusable Core Model that defines a generic registry item. The fourth edition (2023) documents modelling conventions, conformance rules and modular packages used to structure registry implementations.
Key Topics and Technical Requirements
The standard is organized into clear clauses that set modelling, conformance and structural requirements:
- Modelling approach (Clause 5): Guidance on applying a metamodel, use of UML packages, class diagrams and extensibility patterns.
- Core Model (Clause 6): Basic and core classes, predefined datatypes (Boolean, Date, Datetime, Integer, String, Text, Phone_Number, Postal_Address, etc.) and reusable constructs for registry item definitions.
- Identification (Clause 7): Metamodel for uniquely identifying registry items (scoped identifiers, namespaces).
- Designation and Definition (Clause 8): Metamodel for names, labels, definitions, naming conventions and language/context-aware designations.
- Registration (Clause 9): Rules and metadata about how items are registered, lifecycle and provenance.
- Classification (Clause 10): Structures for categorizing items, taxonomies and association classes.
- Mapping (Clause 11): Metamodel constructs to express mappings and relationships among registry items.
- Conformance (Clause 4): Levels and profiles for conforming implementations, implementation conformance statements and roles for registration authorities.
The document emphasizes extensibility, clear terminology, and formal specification practices to support interoperable metadata registries.
Practical Applications
ISO/IEC 11179-3:2023 is intended for practical metadata management and semantic interoperability use cases:
- Building and operating metadata registries / data dictionaries for government, finance, health or enterprise environments.
- Designing metadata management solutions that require consistent identification, naming, classification and mapping of data elements.
- Implementing data governance programs that need standard metadata models for provenance, registration and conformance.
- Enabling system integration, API metadata catalogues and semantic mapping tools to exchange metadata reliably.
Who Should Use This Standard
- Metadata architects and data modelers
- Data governance leads and information managers
- Software vendors of metadata registry, catalog and data governance tools
- Standards bodies and registry administrators
