Overview
ISO/IEC TR 19583-24:2025 - "Information technology - Concepts and usage of metadata - Part 24: 11179-3:2013 Metamodel in RDF" specifies how the ISO/IEC 11179-3:2013 conceptual metamodel is represented as a formal, machine‑readable schema using the W3C Resource Description Framework (RDF). The technical report documents the mapping principles and conventions used to translate classes, attributes and associations of the 11179 metamodel into an RDF schema (the schema artefact is published separately). It is primarily a specification of structure and mapping rules rather than a tutorial on RDF or a full primer on the ISO/IEC 11179 series.
Keywords: ISO/IEC TR 19583-24:2025, ISO/IEC 11179-3:2013, RDF schema, metamodel, metadata registry, semantic interoperability.
Key technical topics and requirements
- Mapping principles and conventions: Defines the guiding principles used to turn UML/metamodel constructs from ISO/IEC 11179-3:2013 into RDF constructs.
- Use of RDF and RDF vocabularies: Specifies how RDF and RDF-based vocabularies are applied to represent metamodel classes, attributes and associations.
- Schema conventions: Documents naming, namespacing and schema structuring conventions used in the formal RDF representation.
- UML stereotypes and metamodel regions: Covers how UML stereotypes and different metamodel regions (Basic types, Basic Classes, Identification, Designation & Definition, Registration, Concepts, Binary Relations, Data Description, elements related to ISO/IEC 11179‑6) are organized and mapped.
- Scope and normative references: The report is normative with respect to the structure of ISO/IEC 11179-3:2013; it does not replicate full explanatory material on RDF or the entire 11179 series.
- Artefact availability: The formal RDF schema is available as a separate downloadable artefact for direct use.
Practical applications and who would use this standard
- Metadata architects and metadata registry implementers who need a formal target model to map their registry designs to the ISO/IEC 11179 conceptual model.
- Semantic web engineers and ontologists who want a standards-based RDF representation of the 11179 metamodel for use with RDF tools (SPARQL, triplestores, Linked Data tooling).
- Data stewards and integration teams seeking improved interoperability between registry products by mapping implementations to a common RDF target model.
- Vendors and open‑source projects creating metadata registry products can use the RDF schema as an exchange format for machine-readable metadata.
Benefits: enables machine‑readable exchange, eases mapping and interoperability testing, and allows instantiation of metamodel elements in RDF for direct exchange between registry systems.
