This document describes the deliverable D2 “Exemplary standardised metadata templates for Geo-Bio samples (vegetation, water, sediment, rock samples) for all use cases” of the project FAIR Workflows to establish IGSN for Samples in the Helmholtz Association (FAIR WISH) funded by the Helmholtz Metadata Collaboration (HMC). Deliverable D2 is part of work package 3 “Domain-specific metadata for terrestrial and aquatic Geo-Bio samples (vegetation, sediment, water, rocks)”. The template presents the suggested metadata elements for sample descriptions of different sample types relevant in the FAIR WISH context and shall serve as the basis for batch uploading sample-metadata to the IGSN server. The modular template was developed as an all-in-one solution for the varying use cases, with the ability for users to select only the variables needed for their specific sample type. This template can already serve for the description of individual samples and will be further developed for hierarchical sample structures later during the project (i.e. vegetation plot > soil pit > soil horizon > soil 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.
