Versioning refers to the documentation of all changes made to research data during the work process. It is recommended to save a new version of the data for each adjustment to ensure traceability. This can be done manually using versioning schemes (e.g., numbering: Version 1.3.2) or by using versioning software like Git. Versioning occurs during the research process itself but can also be applied retrospectively to already published research data to provide third parties with the correct version for reuse.
