This Implementation Guide (IG) brings together base and core HL7® FHIR® artifacts designed specifically for the European context.
It provides a foundation for interoperability, ensuring reusability across national projects, European initiatives, and derived HL7 Europe guides.
The guide supports:
Developers and implementers who need common building blocks.
Policymakers and program leads who require consistent definitions for EHDS-aligned projects.
Standards experts who wish to build on a harmonized European foundation.
The HL7 Europe Base and Core Implementation Guide provides a layered approach to FHIR interoperability in the European context; and it aims to support a coherent and reusable set of FHIR specifications across Europe.
It includes:
Base profiles. Loosely constrained baseline definitions of common European concepts (e.g., Patient, Practitioner). They provide flexibility and serve as the foundation for Core and derived profiles.
Core profiles. More constrained profiles designed for reuse across most European IGs. They introduce essential constraints, can often be used directly, and pursue alignment with IPS.
See the Introduction page for detailed explanations of Base and Core profiles, their relationship with Extensions and scoped IGs, and their alignment with EHDS and IPS.
This guide is published for two HL7 FHIR versions:
Both versions are maintained by HL7 Europe and evolve based on community feedback and EHDS requirements.
