Remote Terminology Services
The Remote Terminology Service Enabled setting enables the use of a remote terminology service for validation. This can be useful in situations where a central terminology service exists that should be used by all FHIR services for an organization, or where a specialized terminology server should be used for advanced validation.
As shown in the diagram above, a Remote Terminology Service may be used with either Endpoint Validation or Repository Validation.
The remote terminology service must be configured on the FHIR Storage module that is being used for validation support. When enabled, profile StructureDefinition resources will still be fetched directly from the validation support repository, but any validatation request operations (e.g. $lookup, $validate-code, $expand, $translate) will be forwarded to the remote terminology server.
This setting expects to be configured by providing the base URL for a server that implements the FHIR Terminology Service profile. When using a remote terminology server, the following operations may be invoked against the remote server on an as-needed basis:
FHIR Terminology Servers known to work in this configuration include:
