DSpace-CRIS is becoming an increasingly popular open source alternative to implement an institutional research information management system (RIMS/CRIS): with 54 instances in 21 different countries on the euroCRIS Directory of Research Information Systems (DRIS) at the time of writing, DSpace-CRIS is the 6th most popular CRIS software solution in the directory (as well as by far the most popular open source one). This is because its expanded data model allows the main research entities (such as researchers, organisations, projects, publications, datasets, etc) to be effectively collected and cross-linked. In January 2026 the Vietsch Foundation awarded a project to euroCRIS, 4Science and the Technical University of Hamburg to expand the DSpace-CRIS data model so that it becomes possible to add instruments and facilities to the snapshot for the institutional research activity. The project plan includes the modelling of this new CERIF research entity by euroCRIS on the basis of the work done by the RDA PIDINST WG, its implementation in the DSpace-CRIS version under development by 4Science and its real-life testing by the Technical University of Hamburg via their DSpace-CRIS-based institutional CRIS TORE. This talk will summarise the project achievements and the lessons learned at the time the presentation gets delivered.
