Aidbox transitions to the FHIR Schema engine

February 5, 2025

Aidbox is undergoing a significant architectural shift by fully adopting the FHIR Schema engine that has been used in production environments by multiple Aidbox customers.


As part of this transition, the existing zen and EA (Entity/Attribute) engines will be deprecated in July 2025. They will be moved to Long-Term Support (LTS) for two years, after which they will reach end-of-life.

Benefits of FHIR Schema engine

The adoption of FHIR Schema brings several benefits to Aidbox, including:

FHIR conformance
Fully supports FHIR StructureDefinitions and FHIR npm packages, ensuring compatibility with the latest standards and tools in the FHIR ecosystem.

Smarter validation
The FHIR Schema engine supports advanced features like FHIRPath invariants, slicing, and extensions, which allow you to apply precise, context-aware rules for more accurate and reliable validation of your resources. Plus, it gives you the flexibility to turn specific validation rules on or off based on your needs — so you stay in control without losing compliance.

Better performance
The FHIR Schema engine is 100 times faster than the official FHIR validator and 17 times faster than the zen validator. It is especially critical in high-load environments.

Ease of use
Aidbox integrates with the official FHIR Implementation Guide (IG) feed, featuring 700+ unique IGs that can be loaded to Aidbox in minutes. Aidbox will resolve and load transitive dependencies.

Dynamic configuration
Aidbox enables dynamic configuration with FHIR packages and canonical resources via UI and API with no restarts.

Timeline

July 2025:

Health Samurai will publish Aidbox 2507.x image that will be considered an LTS (long-term support) version. This version will receive only critical security fixes for 2 years and will be the last version that supports zen and Entity/Attribute engines. 

August 2025 and later

Starting from 2508.x version Aidbox will work using the FHIR schema engine only. Everything defined using zen and Entity/Attribute will not work.

July 2027:
Zen and Entity/Attribute engines will reach end-of-life. LTS support will end and no longer receive updates.

I skipped a lot of recent conferences to prioritize attending FHIR Camp 2024 in Portugal the week before last. It was well worth the trip! It was great to hear Grahame Grieve give the background story on how FHIR came to be an open source effort. The open source angle is really important and unique in that it will require a lot of meaningful collaboration and perhaps unprecedented transparency (things we're not great at in the US) to advance these standards in the coming years. There is and will be a lot of opportunity for people to develop and offer FHIR expertise.
