Step-by-step instructions

wget ftp://ftp.fu-berlin.de/misc/movies/database/frozendata/*gz
  1. get imdbpy and the imdbpy2sql.py script
git clone git@github.com:cinemagoer/cinemagoer.git
pip install cinemagoer
pip install --force-reinstall "SQLAlchemy==1.4"
pip install psycopg2-binary 

cd cinemagoer/bin
python imdbpy2sql.py /directory/with/PlainTextDataFiles/ -u scheme://[user[:password]@]host[:port]/database[?parameters]

Note that this database has some secondary indexes (but not on all foreign key attributes). You can export all tables to CSV:

psql < export_csv.sql

To import the CSV files to another database, create all tables (see schema.sql and optionally fkindexes.sql) and run the same copy as above statements but replace the keyword "to" by "from".
