This workshop provides an opportunity to learn about the functionality of a reputable repository developed in the project NFDI4Health and NFDI4Health Task Force COVID-19, which is a part of NFDI4Health. NFDI4Health is one of the funded consortia of the National Research Data Infrastructure programme of the DFG. German Central Health Study Hub aims to make research data from clinical, public health and epidemiological studies as accessible as possible to people and machines. This does not mean, however, that the data are publicly accessible and can be reused without restriction. Rather, the aim is to open up research results and data for new usage scenarios within the legal and technical limits. With open science becoming a standard practice in research, university and research libraries are increasingly tasked with providing services to support the FAIR publication of research data. Many German and European research grants require a mandatory strategy for publishing research data in their application forms. Alongside education on good research data management (RDM) practices, selecting a suitable repository is an important step in this process. Additional to the target audience of researchers, the workshop might give open science educators another tool in their toolbox to offer RDM services to researchers.During a hands-on session, participants will input a provided dataset into the metadata fields, with the chance to ask questions and discuss their experiences. This highlights potential challenges during metadata input and equips fellow educators to anticipate user questions. Descriptive metadata is crucial for the findability of research data, and continued access is ensured by using an appropriate repository. Reusability increases with comprehensive documentation and meaningful context information for any dataset. In addition to an introduction to core RDM principles and the reasons and benefits of publishing research data, there will be interactive elements to further awareness of the importance of metadata and good documentation practices.
