Notice

The official version of the OHIE workflows can be found in the OpenHIE Architecture Specification.

Overview

Description: This workflow enables requested metadata to be sent from an interlinked registry to another system.  In DATIM, it will be used to send data from the interlinked registry with the source metadata (indicators, mechanisms, sites) to another interlinked registry.  

Referenced Standards and APIs

Assumptions and Prerequisites

  • Metadata being requested has already been populated in the ILR (interlinked registry).   

Actors

External System Actor (Actor outside this HIE)

  • The system requesting the updated metadata (sites, mechanisms and/or indicators).  

OpenHIE System Actors (Actors within the HIE receiving the request for updated metadata.)

  • IL -The Interoperability Layer (IL) is the component that enables easier interoperability between disparate information systems by connecting the infrastructure services and client applications together. An interoperability layer receives transactions from the external system and coordinates interaction between components of the HIE and provides common core functions to simplify the interoperability between systems.
  • ILR - The interlinked Registry containing the metadata (sites, indicators and / or mechanisms) requested by the external system.
