The project pursues the goal of making the complete dataset available for research. The data and the web interface can freely be republished elsewhere especially if the present website is no longer updated. For this end, the entire dataset is licensed under the Creative Commons Attribution 4.0 International (CC BY 4.0) license, and the source code is published under the MIT License.
The website runs on an Apache 2.4 server under Debian, using PHP 7.3.31 and MariaDB 10.3.31 (also tested to work with PHP 8). It uses no custom packages and can run without root privileges (it can basically be deployed on any shared web-hosting).
During development, documentation and source code are made available on GitHub. A draft of the database structure explains the database model.
The database dump is published in the open-access repository Zenodo under doi:10.5281/zenodo.1411391.
