The service re3data, the Registry of Research Data Repositories, currently lists over 2700 digital repositories across all scientific disciplines and is used by researchers and other services worldwide. A variety of funders, publishers, and scientific organizations refer to re3data within their guidelines and policies, recommending it as a trusted service to researchers looking for appropriate repositories for storage and discovery of research data. Since January 2020, the re3data COREF project has been funded by the DFG to further develop and enhance the registry service. The talk gives a general introduction as well as a demo of the service, in particular the indexing and curation process. We take a brief look at the subject classification implemented by re3data and examine which repositories indexed in re3data are associated with institutions participating in NFDI4Ing. We conclude by opening a discussion with the audience with the goal of identifying options to ensure good representation of research data repositories for engineering sciences.
