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.
2 In the context of this part of ISO/IEC 20944, the term mandatory requirement is defined as in ISO/IEC Guide 2:2004, subclause 7.5.1: a requirement of a normative document that must necessarily be fulfilled in order to comply with that document. There is no implication that the aforementioned requirement is compulsory by law or regulation. This kind of mandatory requirement is also known as an exclusive requirement.
3 ISO/IEC Guide 2:2004, subclause 7.5.2 defines the term optional requirement, which includes the following note: An optional requirement may be either: a) one of two or more alternative requirements; or b) an additional requirement that must be fulfilled only if applicable and that may otherwise be disregarded.
