A particular challenge in implementing the FAIR principles (findability, accessibility, interoperability, reusability) is the cross-domain interoperability of research data. The FAIR Digital Object (FDO) concept seems to be a promising generic approach to solve this problem. However, there is a lack of both a technical specification of the concept and community-driven show cases that approach the problem from a bottom-up perspective. The GO FAIR Implementation Network on "Cross-Domain Interoperability of Heterogeneous Research Data (GO Inter)", coordinated by GESIS, organized two hackathons on 18 and 19 May 2020 and on 1 and 2 July 2020 under the direction of Peter Mutschke, which addressed precisely this problem from the perspective of real use cases. Both hackathons took place as online meetings with about 20 participants from 15 member organisations of the GO Inter network. The goal of the hackathons was to discuss and operationalize FDO models for cross-domain search and linking of research data, for semantic artifacts and services, and for cross-phase data exchange across the entire research life cycle. Furthermore, the aim was to contribute to a common understanding of the FDO concept from different application perspectives.
