The Mapping Open Science and Interdisciplinary Connections (MOSAIC) hub transforms how researchers discover and engage with Open Science globally. This dynamic platform maps the evolving ecosystem of Open Science initiatives, providing unparalleled visibility into resources from diverse disciplines and regions. Beyond simple discovery, MOSAIC illuminates relationships between resources, institutions, and experts that might otherwise remain hidden. It serves as both compass and bridge for navigating the complex landscape of open, transparent, and reproducible science worldwide.
