For years, a script titled `collate_samples_SvenjaMax.py` was used in a working group for data analysis. The script had been brought intp the group years ago by a doctoral student named Max and had been repeatedly expanded and adapted. In order to follow the guidelines of good scientific practice, the plan was to publish the script together with the next publication.
To do this, it first had to be clarified whether all authors agreed to this, as the script had not yet been provided with a license. The former employees were painstakingly identified and asked for permission. However, they were only unable to identify Svenja since not even Max could remember who she was.

Source code/script code also counts as research data and should be documented, archived and published with an appropriate license. Dedicated versioning systems such as GitLab as well as classic commenting of source code can be used for documentation. It is essential that it is clear who created or changed the script and when.
