The LOGD project investigates the role of Semantic Web technologies, especially Linked Data, in producing, enhancing and utilizing government data published on and other websites. Large portion of government data published on the Web are not necessarily ready for mashups. The Tetherless World Constellation (TWC) is now publishing over 8 billions RDF triples converted from hundreds of government-related datasets from and other sources (e.g. financial data, non-US government data) covering a wide range of topics (e.g. government spending, energy usage and public healthcare). We are also get these data inter-linked and building mashups using popular Web tools and APIs.
