FHIRconnect: Towards a Seamless Integration of openEHR and FHIR
[2511.14618] FHIRconnect: Towards a seamless integration of openEHR and FHIR
Research was conducted on achieving seamless interoperability between openEHR and HL7 FHIR standards.
Summary
This paper proposes FHIRconnect, a novel domain-specific language (DSL) and transformation engine, to address the interoperability challenges between openEHR and HL7 FHIR caused by fundamental data modeling differences. It enables standardized, bidirectional data exchange, providing a technical foundation for advancing semantic interoperability in healthcare IT systems.
Key Players
Details
This research aims to solve the interoperability challenge arising from fundamental differences in data modeling approaches between openEHR and HL7 FHIR. To achieve this, the authors developed 'FHIRconnect,' a novel domain-specific language (DSL) and an open-source transformation engine. This approach features a triple-layered architecture that leverages international archetype-based foundations while supporting local customizations. Key achievements include successfully mapping 24 international archetypes to 15 FHIR profiles across seven clinical domains. By providing a comprehensive DSL with formal specification for openEHR-FHIR transformation, along with an open-source execution engine (openFHIR) and an accessible mapping library, the work enables community-driven mapping standardization. This significantly reduces reliance on custom ETL solutions, thereby establishing a technical basis that advances both syntactic and semantic interoperability in healthcare IT systems built on open standards.
