Converting governmental datasets into linked data

Linked Data provide many benefits to data consumers, but many publicly available datasets are still released in the Comma Separated Values (CSV) format, a ubiquitous common denominator. We introduce a methodology to transform such datasets into Linked Data.

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.
