General

ISO/IEC 20944 is a series of International Standards that describe codings, APIs, and protocols for interacting with an ISO/IEC 11179 metadata registry (MDR).

This part of ISO/IEC 20944 provides the overview, framework, common vocabulary, and common provisions for conformance for ISO/IEC 20944. It addresses the following data interoperability features1:

- a common framework for variety control: harmonized concepts for conforming implementations and strictly conforming implementations;

- harmonized provisions, such as mandatory requirements 2 and optional requirements 3 , and their consistent application across all bindings of ISO/IEC 20944;

- harmonized and consistent treatment of data elements with varying data obligation attributes (e.g., mandatory, conditional, optional, extended) and varying data longevity attributes (e.g., in-use, obsolete, reserved, etc.).

This part of ISO/IEC 20944 also includes a rationale that guided its development. The rationale also discusses the harmonized use of profiles (e.g., subsets, supersets, changes, etc.) of the data structure and data elements.

1 The concept of data interoperability applies to metadata when metadata is treated as data, e.g., metadata item attributes (as specified by ISO/IEC 11179-3) that are transferred or exchanged. The concept of data interoperability is different from metadata interoperability (agreement upon the meaning of descriptive data), which is outside the scope of ISO/IEC 20944.
