Abbreviation: ISO-11179 Formally known as the ISO/IEC 11179 Metadata Registry (MDR) standard.
Definition: is an international standard for representing metadata for an organization in a metadata registry. The 11179 standard is a multipart standard that includes the following parts:

  • 'Part 1: Framework'. Published in 2004.

This part of ISO/IEC 11179 introduces and discusses fundamental ideas of data elements, value domains, data element concepts, conceptual domains, and classification schemes essential to the understanding of this set of standards and provides the context for associating the individual parts of ISO/IEC 11179.

  • 'Part 2: Classification'. Published in 2005.

This part of ISO/IEC 11179 provides a conceptual model for managing classification schemes. There are many structures used to organize classification schemes and there are many subject matter areas that classification schemes describe. So, this Part also provides a two-faceted classification for classification schemes themselves.

  • 'Part 3: Registry metamodel and basic attributes'. Published in 2003.

This part of ISO/IEC 11179 specifies a conceptual model for a metadata registry, and a set of basic attributes for metadata for use when a full registry solution is not needed.

  • 'Part 4: Formulation of data definitions'. Published in 2004.

This part of ISO/IEC 11179 provides guidance on how to develop unambiguous data definitions. A number of specific rules and guidelines are presented in ISO/IEC 11179-4 that specify exactly how a data definition should be formed. A precise, well-formed definition is one of the most critical requirements for shared understanding of an administered item; well-formed definitions are imperative for the exchange of information. Only if every user has a common and exact understanding of the data item can it be exchanged trouble-free.

  • 'Part 5: Naming and identification principles'. Published in 2005.

This part of ISO/IEC 11179 provides guidance for the identification of administered items. Identification is a broad term for designating, or identifying, a particular data item. Identification can be accomplished in various ways, depending upon the use of the identifier. Identification includes the assignment of numerical identifiers that have no inherent meanings to humans; icons (graphic symbols to which meaning has been assigned); and names with embedded meaning, usually for human understanding, that are associated with the data item's definition and value domain.

  • 'Part 6: Registration'. Published in 2005.

This part of ISO/IEC 11179 provides instruction on how a registration applicant may register a data item with a central Registration Authority and the allocation of unique identifiers for each data item. Maintenance of administered items already registered is also specified in this document.
