We love AJuM!

This small library is a Python wrapper for ajum.de, querying the book review database of the german working group for children's and youth literature and media ("Arbeitsgemeinschaft Jugendliteratur und Medien" or "AJuM"), which is part of the german Education and Science Worker's Union ("Gewerkschaft Erziehung und Wissenschaft" or "GEW").

We deem their work to be invaluable for kindergartens, (pre)schools, universities and other educational institutions. We are thankful for AJuM's commitment and want to give something back by spreading the word and provide an easy way to interact with their review database.

Note: We DO NOT want to disrupt their services in any way, so by default the responsible function sleep()s for three seconds after each API call. Furthermore, as downloading reviews just to build an index file means making A LOT of requests, we included index.json. It was created using strict mode (which means that invalid ISBNs were skipped) and contains all review IDs per ISBN - currently totalling 44757 (valid) ISBNs with 83710 reviews (averaging 1.87 reviews per ISBN).

Getting started

Running setup.bash will install all dependencies inside a virtual environment, ready for action:

# Set up & activate virtualenv
virtualenv -p python3 venv

# shellcheck disable=SC1091
source venv/bin/activate

# Install dependencies
python -m pip install --editable .

From there, it's easy to roll out your own script:

from src.ajum import Ajum

# Initialize object
ajum = Ajum()

# Fetch review data
data = ajum.get_review('SOME_ID')

For more examples, have a look at src/cli.py and src/ajum.py to get you started - feedback appreciated, as always!
