DiSSCo (Distributed System of Scientific Collections) is a world-class Research Infrastructure on the EU ESFRI (European Strategy Forum on Research Infrastructures) roadmap currently aiming to become an ERIC (European Research Infrastructure Consortium). Currently DiSSCo entered its Transition phase. The DiSSCo RI aims to create a new business model for one European collection that digitally unifies all European natural science assets, sharing common access, curation, policies, and practices across countries while ensuring that all the data complies with the FAIR principles (Findable, Accessible, Interoperable, and Reusable data). DiSSCo -the largest ever formal agreement between natural history museums, botanic gardens, and university collections in the world, brings together about 1.5 billion collection items, 5000 scientists, 170+ Institutions, and 23 countries working together
