Introduction

This implementation guide includes information models created in Xt-EHR project. Information models (or logical data models) are the basis for designing the EHDS data exchange format (EEHRxF).

Specification

Xt-EHR Commons IG is a base for all the other implementation guides created in Xt-EHR project. FHIR Implementation Guides are created in cooperation with other EU projects working on EHDS implementation (please find the links under specific use cases).
Information Models IG should be used as a basis for all the use cases to make sure common data objects (patient, medication, etc) are modelled in a consistent way. Use case specific FHIR implementation guides shall include mappings to information models.

The principles of metada management, including information models, are described in Xt-EHR Metadata IG.

Content of the guide is based on many earlier works. Common sources for all use cases include:

• eHealth Network guidelines (including the results from eHN Subgroup of Semantics guideline consistency task force);
• MyHealth@EU requirements catalogue;
• X-eHealth project;
• XpanDH project.
