Health informatics - Harmonized data types for information interchange

This standard provides a set of datatype definitions for representing and exchanging basic concepts that are commonly encountered in healthcare environments. It specifies a collection of datatypes suitable for use in health-related information environments, declares the semantics of these datatypes, and provides UML definitions and XML-based representations.

The standard offers a useful contribution to the internal design of health information systems, but it is primarily intended for defining external interfaces and messages to support communication between them.
