Demonstrating the FHIR Extended Operation Composition/$document

Per the specification, a client can ask a server to generate a fully bundled document from a composition resource. I’ve pulled together a Postman to help demonstrate this feature on the IBM FHIR Server. Download the Postman 2. Update the SERVER_HOSTNAME 3. Update the Authorization for your username and password 4. Click Tests > Run 5. Click Run 6. You’ll see the tests run. 7. Click on the Tests of Interest, and then check the curl you are interested, such as: Good Luck with Composition/$document.

Recipe: Reindexing with fhir-bucket and the IBM FHIR Server

The IBM FHIR Server enables user defined and implementation guide defined SearchParameter definitions and is constantly improving Specification conformance. Given these dynamic changes, the IBM FHIR Server Search parameter values may require refresh to optimize the Search and Retrieval of the data in the operational data store.

Recipe: Running the IBM FHIR Server behind a Reverse Proxy

A common deployment pattern for the IBM FHIR Server is to run the Application Server behind a reverse proxy (e.g. OpenShift Route, Kubernetes Ingress, NGINX or API Gateway). By default, the IBM FHIR Server runs under the https://localhost:9443/fhir-server/api/v4 context root and URI. With a modest configuration change, one can change to a context root (baseUrl) or use the X-FHIR-FORWARDED-URL to forward the incoming url to the IBM FHIR Server (expected to be from a trusted reverse proxy).

Postgres and Vacuum with the IBM FHIR Server: Debugging Details

The IBM FHIR Server stores resources in the PostgreSQL database and uses a relational model to store historical FHIR Resource and enable search on the latest FHIR resources. The resource data is spread in a relational model that is occasionally tweaked in order to improve search or optimize the retrieval using the relational model. This article outlines debugging with VACUUM on Postgres.

Recipe: IBM FHIR Server – Adding a Custom Extended Operation to the IBM FHIR Server

The IBM FHIR Server has support for extended operations beyond the standard C-R-U-D. The Extended Operations are supported at the System, Resource, and Instance levels. Operations are packaged as JAR files, and the IBM FHIR Server loads the specific Operation using the Java ServiceLoader framework at startup. This document outlines how to add a custom extended operation to the IBM FHIR Server.
