LINKED DATA DOWNLOADS
The data underneath Constitute are prepared as open-linked data in order to provide for efficient human and machine consumption, following the standards of the Semantic Web. For those unfamiliar with the standards and the rationale for such data, the W3C site and the Wikipedia entries on “Linked Data” and the “Semantic Web” are good places to start.
We provide Linked Data dumps in three forms:
- The ontology includes the project’s conceptual inventory together with the constitutional excerpts, and is available as an OWL ontology (.owl).
- The metadata includes selected attributes for the constitutions and is available as an N-Triples (.nt) file
- Each country page includes data on the constitutional excerpts of the country with the corresponding topics available as N-Triples (.nt), Turtle (.ttl) and RDF/XML (.xml) files.
TABULATED DATA DOWNLOADS
Analysts can also access “tabulated” versions of the excerpt data from the site itself. After “pinning” an excerpt, an entire search, or a comparison, visit the Pinned page to select and export custom slices of the data as .csv files (as well as .pdfs and Google Docs).
Developers and data enthusiasts can access Constitute's underlying data through an API, the documentation for which is here.
We also host an endpoint where humans and machines can can query the Constitute data directly with SPARQL code, a standard query language for the Semantic Web. Those who do not “speak” SPARQL will find a link to example queries, which are easily adaptable.
DOCUMENTATION OF TOPICS AND COUNTRIES
All of the data are from, or were collected for, the Comparative Constitutions Project. Some English translations are used with permission from HeinOnline and the Oxford Constitutions of the World. Many of the Arabic texts were prepared by International IDEA, in partnership with the Constitute team. Some of the Spanish texts were prepared in partnership with the Human Rights Lab of the University of Los Andes.
