README.md

Extract the MODS/ALTO metadata of a bunch of METS/ALTO files into pandas DataFrames.

Build Status

modstool converts the MODS metadata from 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.

alto4pandas convets the metadata from ALTO files into a pandas DataFrame.

Column names are derived from the corresponding ALTO elements. Some columns contain descriptive statistics (e.g. counts or mean) of the corresponding ALTO elements or attributes.

Usage

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

~~ alto4pandas /path/to/a/directory/full/of/alto_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()`.

% modstool /srv/data/digisam_mets-sample-300 INFO:root:Scanning directory /srv/data/digisam_mets-sample-300 301it [00:00, 19579.19it/s] INFO:root:Processing METS files 100%|████████████████████████████████████████| 301/301 [00:01<00:00, 162.59it/s] INFO:root:Writing DataFrame to mods_info_df.pkl


In the next example we convert the metadata from the ALTO files in the test data
directory:
