The PSI Data Catalogue is a centralized platform powered by SciCat that streamlines the entire lifecycle of scientific data, from initial cataloging to long-term archiving. Designed to eliminate the silos of cross-domain research, it provides a unified hub where users can manage metadata, search for existing datasets, and securely share or publish their findings with unique DOIs. By integrating directly into diverse research infrastructures, the system automates discovery and collaboration, ensuring that high-quality data remains findable and accessible to the global scientific community. This infrastructure empowers organizations to transition toward an open data culture, directly supporting the transparency and reproducibility required for modern scientific innovation.
