This document describes requirements for collections of metadata about data elements and their
containing models and datasets in a healthcare environment. The collection can serve as a repository
or as dictionary describing a set of items in use in a particular domain, organisation or product for
reference, or it can additionally serve as a registry, supporting the development and communication of
standard items to an audience with shared goals.
This document specifies standard refinements that account for the detailed governance and
administration requirements that are particular to healthcare data. It focuses on the description of
data that is persisted in healthcare systems rather than the specification of messages between these
systems. It describes necessary extensions to the ISO/IEC 11179 series and to other International
Standards on metadata originating from ISO/IEC JTC 1/SC 32 to address the wider variety of value
domain types found in healthcare. Where appropriate, it also suggest restrictions/simplifications to
the ISO/IEC 11179 series that promote wider adoption without compromising interoperability between
metadata registries and opportunities for the development of tooling that consumes metadata for the
generation or the parameterization of code.
