OLDP is a web application, written in Python 3.5 and based on the Django web framework, It is used for processing legal text and providing a REST-API and Elasticsearch-based search engine. OLDP is being develop by the non-profit initiative Open Legal Data with the goal of building an Open Data platform for legal documents (mainly court decisions and laws). The platform makes legal information freely accessible for the general public and especially third-party apps.
Our documentation is available here.
A live demo is available here (in German).
- Cases: Court decisions with meta data and content in HTML.
- Laws: Full-text laws and regulations and their corresponding case-law.
- Courts: Browse courts organized by states, jurisdiction and level of appeal from your country.
- Search: A document search engine based on Elasticsearch/Haystack supporting most common search syntax and faceting.
- API: Adding, updating, retrieving and deleting data through CRUD REST API based on DRF including auto-generated API clients from Swagger.
- Themes: Easily adjust the look and feel depending on your countries needs (see German theme).
Before you can use OLDP, you’ll need to get it installed. For a more detailed guide on how to get started with OLDP have a look at: Getting started
To skip the whole installation procedure you can simply run OLDP as Docker container.
Just git clone the repository first and then start everything with a docker-compose up from within the repository directory.
A small tutorial on how to use OLDP with Docker can be found here.
Before anything else you will need to install the application dependencies.
- Python 3.5 with pip (virtualenv or conda recommended)
- Node JS 8.12.x with npm for building JS dependencies
- Database (MySQL, SQLite, ...): All database engines that support Django's DB API should work. MySQL is recommended.
- Elasticsearch 5.4.x: Our search engine backend. Other systems supported by haystack should also work.
- Redis 4.x: Caching engine (optional)
- gcc Required to compile some Python libs
- python-mysqldb, libmysqlclient-dev if you choose MySQL as database
- gettext for Django locales with msguniq
- pandoc convert docbook to HTML (import GG)
- GDAL: Geospatial libraries used by the haystack search module (see here).
# Create virtualenv
virtualenv -p python3 env
source env/bin/activate
# Clone repository to current directory
git clone https://github.com/openlegaldata/oldp.git .
# Install dependencies
apt-get install -y $(cat apt_requirements.txt)
pip install -r requirements.txt
npm install
The first time you run OLDP, you will need to initialize the database with its default blank values. If you want to run OLDP in production mode, you also need to prepare static files and localization.
# Prepare assets (JS, CSS, images, fonts, ...)
npm run-script build
# Prepare database
./manage.py migrate
# Localization (German and English, needed for production)
./manage.py compilemessages --l de --l en
# Prepare static files (needed for production)
./manage.py collectstatic --no-input
Run the following command to start the web app at https://localhost:8000/.
./manage.py runserver 8000
The manage the app settings we rely on django-configurations.
Pre-configured settings can be used by setting the DJANGO_CONFIGURATION environment variable to either Prod, Dev or Test.
You can as well override specific settings from oldp/settings.py with environment variables:
