urbisphere-dm: FileDB [RAW]

Information about the structure of the files and folders on the Urbisphere archive server was stored as database files to help diagnose cases of missing data. The `.db` files are created using 'updatedb'. The `.feather` file is created using Python module `pandas`. It contains patterns identified in folder and file names as locations, instruments, time periods, and so on. The combination is a catalogue called FileDB, which was used to speed up operational searches within millions of file objects. A .sql dump of the latest copy of the metadata is included, enabling advanced, targeted lookups.
