Big data management is a major challenge, as it is necessary to establish a process that ensures quality, findability, accessibility, and reusability of data. In this seminar, we will present practical examples on how to prepare data, document it, and publish it in the repositories of the National Open Access Infrastructure (OAI). You will also learn about the benefits of reusing big data in an HPC environment. Participants can bring one or more research datasets for uploading into the repositories of the National Open Access Infrastructure.
