DOCUMENTATION OF RESEARCH DATA AND CODE
The life cycle of the data as well as the code is described detailed in chapter 3 (Methodology) of the thesis.
Also the Data Management Plan can be helpful (DMP).

If values were used more than once, entries were combined in one cell and separated by " | "


CODE

re3data_extract.ipynb
- Jupyter Notebook in R fetching data about repositories from re3data's API.
re3data_normalize.ipynb
- Jupyter Notebook in R normalizing single fields and splitting up size property
re3data_analysis.ipynb
- Jupyter Notebook in R uncollapsing rows for size sublevel, analysing fields, with on-the-fly-modifications and plots
