Welcome to the Leibniz Center Ontology Project

The Leibniz Center for Law is an interdisciplinary research center that applies techniques from Artificial Intelligence, and knowledge-based systems in particular to the legal field. One of the most salient components in our approach is the construction and use of ontologies as basis for legal knowledge based reasoning. This website is the portal through which we publish the ontologies developed at the Leibniz Center. These ontologies are free to use for non commercial purposes, see License for more details.
