The increasing of health data sources to support clinical practice is opening the path for its secondary use in biomedical research. This changes the research paradigm, from data generation to data management and analysis. Although the potential for secondary use of this data is vast, including the improvement of healthcare systems and the advancement of clinical research, data discovery is challenging. In order to maximize data reusability, the FAIR principles have been developed as a guiding framework for system development. Nevertheless, the discovery and reuse of biomedical data present two main challenges: i) data partners grappling with ethical and social concerns related to data discoverability; ii) clinical researchers struggling to find the best data sources for their research studies. In this paper, we present a platform that provides a set of tools, compliant with the FAIR principles, to help data custodians when sharing data about biomedical databases, while allowing researchers to search for and select databases that meet their specific research needs.
