This paper especially discusses software engineering challenges stemming from creating a long-living software system. It aims at providing a reference implementation for a federated research data infrastructure including interconnected individual repositories for communities and an overarching search based on metadata. The challenges involve a high variety of evolving requirements, the management and development of the distributed and federated infrastructure that are based on exist- ing components, the piloting within the use cases, the efficient training of users, and how to enable the future sustainable operation.en0720-8928
