**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.
