Level:  All - General Audience


Over the last 200 years, countries have replaced their constitution an average of every 19 years. On average, five countries write new constitutions every year. The people who write these documents are often outgunned and under-resourced as they try to search and analyze constitutions from the past.

Enter Constitute (www.constituteproject.org), a new product developed by UT Austin, U Chicago, and University College London with the help of Capsenta. Constitute leverages a rich set of original data about the content of constitutions together with a complete set of constitutional texts. Users can search and extract constitutional passages using a powerful search engine based on Semantic Web technologies and then compare and analyze them. The goal of Constitute is to improve the efficiency and systemization of constitutional design and, thus, to support the independence and self-reliance of constitutional drafters.

Our presentation will:

  1. Introduce Constitute, its features, potential uses, and how it's changing constitution writing in countries like Tunisia, Libya, and Yemen.
  2. Explain how an OWL ontology representing 330 constitutional topics was created.
  3. Describe how the constitutional data was mapped to RDF and OWL using the RDB2RDF standards (Direct Mapping and R2RML) and Capsenta’s Ultrawrap.
  4. Explain design choices (XML schemas vs. RDF/OWL) and lessons learned.
  5. Illustrate how linking to other data sources can enrich Constitute.
