## EHDSAlert to FHIR Flag Mapping

# EHDSAlert → FlagPatientEuCore

**Ongoing alignment:**The models are expected to continue evolving, with updates incorporated into this Implementation Guide to maintain alignment with the EHDS Implementing Acts.

### EHDSAlert → FlagPatientEuCore

 This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR FlagPatientEuCore profile used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSAlert ](https://www.xt-ehr.eu/fhir/models/0.3.0/StructureDefinition-EHDSAlert.html) 
*  **Target FHIR profile:** [ FlagPatientEuCore ](StructureDefinition-flag-patient-eu-core.md)

| Element | Relation | Resource | Element | Notes |
| header | related-to | Flag | . | Dataset-level; not usually carried in Flag as-is. |
| header.subject | equivalent | Flag | subject |  |
| header.identifier | equivalent | Flag | identifier | Copy over all identifiers if multiple. |
| header.author[x] | equivalent | Flag | author |  |
| header.date | no-map | Flag |  | No direct native Flag element for authoring timestamp. |
| header.status | equivalent | Flag | status |  |
| header.source | no-map | Flag |  | No direct native Flag element; consider extension if needed. |
| header.language | equivalent | Flag | language |  |
| description | source-is-broader-than-target | Flag | extensions:note.valueAnnotation.text | The mapping applies if the description represents additional information collected about the alert.`code.text`should be used if it represents the textual rendering of coded content, or textual description of the alert. |
