The OpenHIE Architecture is intended to represent a pattern for key architectural components in a health information exchange. The diagram is a high-level conceptual diagram, or logical overview of the OpenHIE architecture that is intended to be notional. This diagram represents the consensus of the OpenHIE Architecture Review Board as determined through the Architecture Governance and Principles. It is expected that implementations based upon OpenHIE may have more precise lower-level conceptual diagrams and/or physical diagrams.
