The Interoperability Layer is the base of the Platform architecture.
OpenHIM
Console: http://127.0.0.1:9000
Username: root@openhim.org
Password: instant101
As part of the Interoperability Layer setup we also do some initial config import for connecting the services together.
OpenHIM: Import a channel configuration that routes requests to the Data Store - HAPI FHIR service
This config importer will import channels and configuration according to the file openhim-import.json in the folder <path to project packages>/interoperability-layer-openhim/importer/volume.
The interoperability layer that enables simpler data exchange between the different systems. It is also the security layer for the other systems.
This component consists of two services:
Interoperability Layer - OpenHIM for routing the events
Mongo DB for storing the transactions
It provides an interface for:
Checking the transactions logs
Configuring the channels to route the events
User authentication logs
Service logs
Rerun the transactions tasks
Reprocess mediator launching
OpenHIM is based on two 3 main services, openhim-core as a backend, openhim-console as a frontend and mongo as a database.
It is a mandatory component in the stack and the entry point for all incoming requests from the external systems.
