Extract the MODS metadata of a bunch of METS files into a pandas DataFrame.

Column names are derived from the corresponding MODS elements. Some domain knowledge is used to convert elements to a useful column, e.g. produce sets instead of ordered lists for topics, etc. Parts of the tool are specific to our environment/needs at the State Library Berlin and may need to be changed for your library.

Usage

modstool /path/to/a/directory/containing/mets_files

Example

In this example we convert the MODS metadata contained in the METS files in /srv/data/digisam_mets-sample-300 to a pandas DataFrame under mods_info_df.pkl. This file can then be read by your data scientist using pd.read_pickle().
