Therefore, methodical aspects and scientific reasons can speak in favor of a combination of a sample archival system and a research data repository. Such a combination was realized with the Chemotion repository and the Molecule Archive at KIT (Karlsruhe Institute of Technology). The Chemotion repository is a repository for research data related to chemistry, particularly experimental chemistry. Scientists can either upload data directly or interoperably transfer it from an electronic lab notebook to the repository without losing information. The data are peer-reviewed in combination with automatic checks and can then be disclosed with persistent identifiers. Especially for organic chemistry, the repository offers additional functions for direct viewing and analysis of the stored data by discipline-specific research software and thus enables an easy way of re-using the data. The repository follows an open-access policy and is part of the strategy of NFDI4Chem in Germany.
