This document provides a specification for an extension to a Metadata Registry (MDR), as specified in ISO/IEC 11179-3 in which metadata which describes data sets, collections of data available for access or download in one or more formats, can be registered. Since a set can contain a single element, this document enables the recording of metadata about a single data value.
The registered metadata provides information about the data set that can include the provenance of the data set and quality, fitness for role, and risk assessments of the data set.
