The data concept repository is a repository of the metadata used for describing data held in information systems within the New Zealand health sector. This standard defines the required metadata elements and metadata management processes.

Its purpose is to provide a shared and commonly agreed and understood collection of concept definitions, coding nomenclatures and data set definitions.

The standard specifies the key elements of concepts and data sets definitions, provides a framework for the specification of an information model, and sets out the core business/change management processes associated with the repository – specifically the processes around adding new concepts or data sets, and altering or deprecating existing concepts or datasets. The standard recommends the starting point for the repository is ISO/IEC 11179.
