## Logical Models

### EHDS Logical Data Models

The [**Xt-EHR Joint Action**](https://www.xt-ehr.eu/) has developped a set of Logical data models (or information models) - see [**Xt-EHR EHDS Logical Information Models**](https://build.fhir.org/ig/Xt-EHR/xt-ehr-common) Implementation Guide - that have been used as **basis** for the future **European Health Data Space (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 subject to further refinement.

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.

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