# EHDSTravelHistory -> ObservationTravelEuEps

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

**Yellow row/cells:**In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

### EHDSTravelHistory -> ObservationTravelEuEps

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

**Mapping Context**
*  **Source logical model:** [ EHDSTravelHistory ](https://www.xt-ehr.eu/fhir/models/StructureDefinition-EHDSTravelHistory.html) 
*  **Target FHIR profile:** [ ObservationTravelEuEps ](StructureDefinition-observation-travel-eu-eps.md)
