Location Registry (LocoReg)
The location registry provides an overview of health services and where they are located.
Each health service is linked to a location, which in turn is linked to an organization.
The objects are based on the FHIR standards for Organization,
HealthcareService and Location.

FHIR SDK for C#
The API can be consumed by any REST client over HTTP, but it is recommended to use a helper library for the FHIR types. It provides a lot of boiler‑plate code for free, especially when creating objects.
