Narf's FHIR Garden is available on GitHub. The FHIR Garden is a collection of Fast Health Interoperability Standard (FHIR) servers that make health data interchange possible by exposing REST API endpoints. In addition to the FHIR Garden, we also released a set of tools meant to make chaining and comparing these FHIR implementations feasible. FHIR implementations support exporting (and importing) patient data in XML, JSON, and Turtle formats.

Our tools allow us to automate a Game of Telephone (GoT) (Figure 1), where we can create a patient on one FHIR server and then export it into another. Our GoT tools allow researchers to compose long chains and store intermediate results at each hop, allowing us to find implementation discrepancies.
