This Deliverable provides an overview of the ongoing data FAIRness implementation within the Biodiversity and Ecosystem subdomain, also in relation to the overall ENVRI FAIR project developments. Considering the central role assumed by the WP5 Task Forces within the project, the current compliance of the subdomain RIs with Task Forces recommendations has been analysed, through a specific questionnaire administered to all subdomain RIs. Considering this survey results, single RI roadmaps are presented to fill the current gaps. A particular focus is finally reserved to the ongoing subdomain use cases, which are considered a key step in developing interoperability within the subdomain.
