Because Jupyter notebooks are used by Yelp employees for several important business processes, Yelp developed Folium to improve notebook reproducibility through better archiving and sharing capabilities. Folium includes APIs to upload and tag notebooks and import existing notebooks into JupyterHub. It also offers a front-end service to search, preview, and navigate through notebooks (including by identifying similar notebooks). In addition, Folium logs the running environment from the current notebook servers and enables users to parameterize notebooks.
