### DHDR FHIR Implementation Guide This document illustrates the use cases supported by DHDR solution, along with the content and data standard for the DHDR FHIR interfaces. To describe the structure of resources, we use the FHIR structure definition (http://hl7.org/fhir/STU3/structuredefinition.html) format. Each resource type has its definition and schema on the hl7.org/fhir site, linked via the FHIR resource list, along with examples in both XML and JSON formats.
