The system that produces the aggregate data to be exported. This could be a point-of-service system like an EMR or an HMIS that is sending to another HMIS. It could also be a mediator or other service that produces an aggregate message.
Interoperability Layer (IL)
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 point of service systems and coordinates interaction between components of the HIE and provides common core functions to simplify the interoperability between systems.
The system that will be receiving aggregate data. Examples of this system could be an external HMIS system or an HIE.
