Trifolia-on-FHIR (ToF) supports multiple versions of the FHIR standard: STU3 and R4. It defaults to the FHIR server selected during previous login.

To select a different FHIR server: 

  1. Click the FHIR server button to display the Edit Settings screen. 
  2. In the Selected FHIR Server field, click drop down menu and select the FHIR server.

FHIR Versions in the UI

Depending on the FHIR server and the version it supports, the screens for editing resources may appear (e.g., STU3 vs. R4). The screens in ToF reflect the changes between STU3 and R4 resources. In STU3, for example, ImplementationGuide has "packages" with "resources" inside each package. In R4, ImplementationGuide has "resources" parallel to "packages," and each resource references a package.
