The German Federation for Biological Data (GFBio) comprises around 20 partner institutions from the scientific community. It has been funded by the German Research Foundation (DFG) since 2013 over three project phases, ending in 2022. The project partners, consisting of data centers, data management and IT specialists, were driven by the mission to make biological and environmental data permanently discoverable. Together, the GFBio project partners developed tools and services for researchers along the data lifecycle, which describes the various steps from planning to data collection to publication. One result of the collaboration is the data portal www.gfbio.org, which makes data from 9 affiliated data centers accessible and provides a central point of access to developed services (search, submit, analyse) and support on all issues related to standardization, publication, and management of biological and ecological research data. Internally, work processes were standardized, common standards and formats agreed upon, and technical interfaces created to enable accessibility, harmonization, and (semantic) enrichment of the data.This community collects the outputs from the final phase of GFBio.
