The European Health Data Space as 3LGM2-Based Enterprise Architecture Model.

The European Health Data Space (EHDS) Regulation assigns rights and obligations to the stakeholders of health information logistics across Europe. This implies specific requirements for the architecture of a European health information system. Since enterprise architecture models (EAM) effectively support the development of such information systems, we present an EAM based on the three-layer graph-based metamodel (3LGMs). The EHDS 3LGMs model describes the tasks of the stakeholders, the data to be processed and the necessary application systems and services for primary and secondary use of data. The model is freely available together with the 3LGMs tool.
