Data Types Information Model vRM 1.1.0

This document describes the openEHR Data Types Information Model, which is used throughout the openEHR Reference Model. It supports the harmonisation of data types between information models used by related healthcare services. This helps to reduce the potential for errors, and the need to convert work.

This specification contains scientific and clinical data types used in other openEHR models. It is intended to work not only for the EHR, but also for other models defined by openEHR, such as the openEHR demographic and terminological models.
