## Logical Models

### EHDS Logical Data Models

Logical data models (or information models) for the **European Health Data Space (EHDS)** are **currently being developed** by the [**Xt-EHR Joint Action**](https://www.xt-ehr.eu/). These models will form the **basis of the Joint Action's proposal** for the future EHDS Implementing Act.

They represent **evolving, refined interpretations** of the data sets described in the [**eHealth Network (eHN) Guidelines**](https://health.ec.europa.eu/ehealth-digital-health-and-care/digital-health-and-care/eu-cooperation/ehealth-network_en#ehealth-network-guidelines), and are expected to be further updated during the Joint Action process.

This Implementation Guide (IG) aims to **align with the emerging EHDS logical models** and to **provide HL7 FHIR profiles** that **realise the requirements identified in these models**.

The EHDS logical models currently supported in this version of the guide are listed below. For the most recent and in-progress versions, please refer to the [**Xt-EHR EHDS Logical Information Models**](https://build.fhir.org/ig/Xt-EHR/xt-ehr-common) Implementation Guide.

**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.
