HL7 V3 MODELS, R1 (N3 May 2010)


The document defines the infrastructure for the core models - Data Types, Reference Information, and Vocabulary -- that form the foundation for all Version 3 models. In addition to specifying the representations of these models, the document specifies how these three models should be used in combination to support implementation of V3 standards.


As Version 3 was launched, the development of the RIM, Data Types and Vocabulary proceeded in parallel guided by the stipulations in the Version 3 Development Methodology, and a growing set of understandings as to how best to apply these models to health care communication. As Version 3 matured, the responsible work groups realized that there was a "missing" specification that should be voted on by the HL7 membership, and that should specify how to use these three models in a coordinated fashion both to develop and to implement the Version 3 specifications. "Core Principles" (this document) is that "missing specification. This document specifies:

How each of the three models in conceived and what is its role in supporting V3 specifications.

How and when the linkages or bindings between these models are defined and maintained.

How these models and their bindings are represented in instances of communication.

The responsibilities of developers and implementers for these models.
