Common questions

Is Open Legal Data (Germany) safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed today, and the latest version (0.16.5) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

OLDP: Open Legal Data Platform

[!NOTE]

We're back! This project is getting a fresh update - join us on Discord to help revive it.

OLDP is a Web application, written in Python 3.12 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.

Demo

A live demo is available here (in German).

Features

  • 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).

Installation guide

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

Docker

To skip the whole installation procedure you can simply run OLDP as Docker (or Podman) container. Steps:

  1. Clone the repository git clone https://github.com/openlegaldata/oldp
  2. Rename the local env file (local.env) to .env
  3. Run make up, which will either call the docker or podman container engine depending on your setup
  4. Navigate to localhost:8000 to view the site

A small tutorial on how to use OLDP with Docker can be found here.

Dependencies

Before anything else you will need to install the application dependencies.

  • Python 3.12 with pip (uv recommended)
  • Database (MySQL, SQLite, ...): All database engines that support Django's DB API should work. MySQL is recommended.
  • Elasticsearch 7.17.x: Our search engine backend. Other systems supported by haystack should also work.
  • 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 with uv

uv venv --python 3.12 source .venv/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) uv pip install -e ".[dev]"

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, ...)

./manage.py compress

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

Run the following command to start the web app at http://localhost:8000/.

./manage.py runserver 8000
Settings

To manage the app settings we rely on django-configurations. Pre-configured settings can be used by setting the DJANGO_CONFIGURATION environment variable to either ProdConfiguration, DevConfiguration or TestConfiguration. You can also override specific settings from src/oldp/settings.py with environment variables (all prefixed with DJANGO_).

See the Configuration reference for the full list of environment variables (database, Elasticsearch, caching, email, MCP, logging, …).
