# EHDS Logical Models to FHIR Profiles Mapping

**Ongoing alignment:**The Xt-EHR logical models are under active revision and continuous refinement. Updates from Xt-EHR will be progressively incorporated into this Implementation Guide to maintain alignment with the evolving EHDS specifications.

### EHDS Logical Models → FHIR Profiles

 The Xt-EHR Joint Action defines EHDS logical data models for core clinical and administrative concepts. This Implementation Guide provides HL7 FHIR profiles that realise those models. 

 The sections below group the EHDS logical models into categories. 

Each table shows:

* the logical model
* the FHIR datatype or profile(s) used in this IG
* a link to the detailed element-by-element mapping

** † ** Mapping with additional clarification note below.

**Scope Clarifications:**
*  The mapping `EHDSObservation → MedicalTestResultEuCore` does not apply to every kind of Observation. Not all observations are medical test results; for example, social history observations are Observation resources but are outside the MedicalTestResult scope. 
*  `EHDSMedicationPrescription` is defined in the HL7 Europe MPD guide context. A prescription is not represented by simply the core ` MedicationRequest` alone; it requires the MPD modelling context and related constraints. 
*  `EHDSDocument` is represented as `CompositionEuCore` when modelling the structured clinical document composition; it is represented as `DiagnosticReportEuCore` when modelling report-oriented diagnostic content and results.
