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()`.
