Throughout this module, we will explore the architecture and technical standards that underpin secure and efficient information exchange within the HealthData@EU infrastructure. You will learn about the deployment and configuration of Domibus (the AS4 protocol under the eDelivery building block) and the HealthData@EU dispatcher, focusing on prerequisites and the configuration for successful implementation, including national deployments to be performed by the national contact points (NCPs). By the end of this module, you will be equipped with the necessary knowledge to ensure secure and efficient cross-border information exchange within the HealthData@EU infrastructure.
