About the Data-gov Wiki

The Data-gov Wiki is a project being pursued in the Tetherless World Constellation at Rensselaer Polytechnic Institute. We are investigating open government datasets using semantic web technologies. Currently, we are translating such datasets into RDF, getting them linked to the linked data cloud, and developing interesting applications and demos on linked government data. Most of the datasets shown on this page come from the US government's Web site, although some are from other countries or non-government sources.

NEW: Visit our experimental DRUPAL site (featuring new demos and tutorials)

Dataset Statistics
Cloud of Government data in RDF

This wiki is currently hosting 312 RDFlized datasets covering the content of 540 out of 6394 datasets released at These datasets contribute 3.73 billion RDF triples.

It also hosts additional RDF-ized datasets including 1 Datasets and 2 Deleted Datasets. These additional datasets together contribute 0.01 billion more RDF triples.
