The first release candidate for the IBM FHIR Server under the Apache 2.0 license.

This release represents a complete overhaul of the internal IBM FHIR Server component that was used within IBM Watson Health, including:

  • a new FHIR R4 object model that implements both the builder pattern for creating valid, thread-safe, immutable objects and the visitor pattern for allowing simple traversal
  • high-performance JSON and XML parsers and generators for readings and writing FHIR objects
  • a high-performance FHIRPath engine that operates directly over the model and supports both instance validation and search parameter extraction
  • an updated JDBC schema and database utilities for deploying a Db2 multi-tenant schema in under 2 minutes
  • numerous changes to support a combined score of 98% compliance on the AEGIS Touchstone Basic and Advanced test suites
  • significant cleanup and refactoring to reduce the surface area of the server implementation
