validation-service-fhir-r4

This service can be used to validate FHIR R4 messages against implementation guides on Simplifier.

Customising the validator

The Simplifier packages to be used for validation are declared in manifest.json. These are downloaded at build time and included in the jar.

Known limitations

• Resources must use FHIR version R4
• The profiles from the Simplifier packages will only be used in one of the following cases:
  • The resource being validated specifies a profile in the meta field
  • The resource being validated is a message, and a matching message definition in the packages specifies which profile to use for a given resource type
  • A capability statement in the packages specifies which profile to use for a given resource type
• The validator does not use a terminology server, so some code systems, including SNOMED, cannot be validated

How to update validator in EPS

From repo root, run:

• make install
• make build-latest

Commit and push changes to a branch. Get merged into main and reference new commit from EPS repo

Run docker service locally

To run the docker image locally use

make docker-run

To run the docker image locally forcing a rebuild of the docker image use

make docker-rebuild-run

To test it is running you can use the following

curl http://localhost:9001/_status

To validate a FHIR message you can use

  -H "Content-Type: application/json" \
  -d "@1-Prepare-Request-200_OK.json"
