Provides measures to support various degrees of interoperability of the EHCRs created on different systems, or different teams on the same system. Aims to enhance the ability of EHCR entries to be communicated or accessed in a way that supports the visual interpretation of original entries by the end-user of a recipient system; facilitates record navigation; enables a limited level of amalgamation of received data sufficient for the generation of longitudinal views; and allows for a limited degree of automated processing, i.e. information retrieval.
