The data that are generated or collected at Research Infrastructures can be very complex. In Social Sciences and Humanities there are multimedia, multilingual sources, and data collections can be surveys, panels, events, or based on registries and contain thousands of variables. To use these data, a newcomer needs training – on the structure, on caveats, on previous results. Such training is part of the SSHOC project and we will give a brief introduction where and how this training can be found. This presentation was part of the Social & Cultural Data – taking the Users’ Perspective session on 28 November 2019 at the EOSC Symposium in Budapest, Hungary.
