An interoperability layer enables disparate health information systems to more easily communicate between each other in order to exchange information.

Process Overview
As a part for the RHEA project an HIE has been developed for maternal health in Rwanda. For more information about this implementation see: here. During this implementation the OpenHIM (http://openhim.org/) was developed. This is expected to work for the pilot implementation for the RHEA project that is planned to run in a single district of Rwanda, however, it is not know if this instance will scale to a national level and if the technology is appropriate for national scale.
As a part of the OpenHIE project this community is tasked with reviewing and evaluating what makes a good interoperability layer going into the future and seeks to determine what technologies would be suit an interoperability layer for our purposes.
Methodology
What is an interoperability layer
Document use cases
Document requirements
Review current OpenHIM architecture
Review current OpenHIM technologies
Performance test current OpenHIM
Generate estimated load figure for national deployment
Create performance testing framework
Gather data from tests
Compile performance data into a report
Investigate and evaluate alternate orchestration/mediation engines or options
Enumerate and explore alternatives
Detail each alternative, it's implications and pros/cons
Develop evaluation tool from requirements
Evaluate each tools against the evaluation tool
Compile results
Investigate use of standards in OpenHIM and each option
Write up results of evaluation
Detail each option, with input from the evaluation results
- Detail the suggested way forward
