scope:

This document provides a specification for an extension to a Metadata Registry (MDR), as specified in ISO/IEC 11179-3:2022, in which metadata that describes concept systems can be registered. The specification in this document, together with the relevant clauses of the specification in ISO/IEC 11179-3, provides the ability to record the following metadata: • Concept systems and associated concepts; • Relations among concepts in a concept system; • Assertions about concepts in a concept system. The metamodel in this document is intended to support the full description of a concept system, including ontologies. Where there is a requirement to register an ontology where the details are defined elsewhere, consider using ISO/IEC 19763-3[7] instead.
