## 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. These models will form the basis of the Joint Action proposal for the future EHDS Implementing Act.

They represent evolving, refined interpretations of the data sets described in the eHealth Network (eHN) 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.

Below is a simplified representation of a laboratory report. The data set comprises several basic parts, as visualised in the diagrams below.

### EHDS Logical Data 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 Implementation Guide.

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