The CATSS database ("Computer Assisted Tools for Septuagint Studies") is a Septuagint database with morphology and Hebrew text alignments (BHS) with text-critical notes. The database can be publicly accessed at http://ccat.sas.upenn.edu/rak//catss.html, and can be retrieved as plain text files. The user must agree to the CATSS' unfortunately limited license. It is not good that this license is so closed, and in the future it would be great to see it opened up as Creative Commons.
While the CATSS database is published online, the dataset is provided in a complicated format which makes using that data difficult. This repository contains a number of Python methods which can be used to automatically retrieve the data and convert it into easy-to-use json files. This is especially crucial with the alignment ("parallel") files, which are quite complicated in their arrangement.
Another goal of this repo is to update, where relevant, the documentation for the alignment dataset, since some notations have not been updated in the docs.
Though the CATSS dataset is not provided under a permissive license, it is still published freely online. It is hoped that the development of these tools will encourage more people to use the CATSS dataset, which in turn will hopefully encourage the license holders to release it under a more open license.
Note that due to the license, the CATSS data itself is not stored in this repository. But you can download your own copy of the data by doing:
from download_catss import download_catss
download_catss()
