This video tutorial with audio contains FAIR WISH expert demonstrations and explanations for using the FAIR SAMPLES Template” of the project FAIR Workflows to establish IGSN for Samples in the Helmholtz Association (FAIR WISH) funded by the Helmholtz Metadata Collaboration (HMC). It is part of Deliverable D3 of work package 3 “Domain-specific metadata for terrestrial and aquatic Geo-Bio samples (vegetation, sediment, water, rocks)”. The ultimate goal of the video tutorial is to instruct users how to use the FAIR SAMPLES Template. The video begins with an introduction to the Helmholtz Metadata Collaboration (HMC), the FAIR WISH project, the International Generic Sample Number (IGSN) and the overall motivation for making samples uniquely identifiable and citable by IGSN assignment. The content then changes to the main part of the tutorial, focussing on the FAIR SAMPLES “Excel” Template, its content and functionalities. In this part, the speaker guides the audience on how to use the template with the different categories of metadata for a sample. FAIR WISH is a joint project between the Helmholtz Centres GFZ, AWI and Hereon. It was was funded 2022-2023 by the Initiative and Networking Fund of the Helmholtz Association within the HMC Project Cohorte 2020 of the Helmholtz Metadata Collaboration Platform HMC.
