Information technology - Metadata registries (MDR) - Part 3: Metamodel for registry common facilities

2Scope / Description

1.1 Structure of a metadata registry This document specifies the information to be recorded in a metadata registry in the form of a conceptual data model: — Clause 5 specifies the approach used to model a metadata registry; — Clause 6 specifies the Core Model of the registry, including basic types and classes to be reused in extending the model. The core model defines a generic “registry item”, from which any type of item that needs to registered can be sub-classed; — Clause 7 specifies the metamodel for Identification of registry items; — Clause 8 specifies the metamodel for Designation and Definition of registry items; — Clause 9 specifies the metamodel for Registration of registry items; — Clause 10 specifies the metamodel for Classification of registry items; — Clause 11 specifies the metamodel for Mapping among registry items.
1.2 Model extensions Other parts of ISO/IEC 11179 extend the core model to support additional functionality, including the following: — ISO/IEC 11179-31[17] provides a metamodel for data specification registration, including support for data elements, data element concepts, conceptual domains and value domains; — ISO/IEC 11179-32[18] provides a metamodel for concept system registration , including support for concept systems and ontologies; — ISO/IEC 11179-33[19] provides a metamodel for data set registration; — ISO/IEC 11179-34[20] (under development) provides a metamodel for computable data registration; — ISO/IEC 11179-35[21] provides a metamodel for model registration.
