The present report is focused on the technical implementation and validation of the COVID-19 clinical research repository developed within the EOSC-Life project. The first section describes the functionality of the repository, split between its two main systems - the TSD infrastructure on the one hand, operated by the University of Oslo, and the Repository Management System (RMS), developed by ECRIN, on the other hand. The RMS is designed to support and record the workflows associated with managing the repository and its interactions with providers, secondary users and requesters. Subsequently, the two systems and their interface to support the repository’s activity are described in detail, including the AAI infrastructure that will be used and shared by both the RMS and the TSD. Finally, the validation strategy that is currently applied to the RMS and to the new, repository-specific elements of the TSD is outlined.
