This document discusses linking government data to the web. It introduces dcat, a vocabulary for describing government data catalogs in RDF. It also describes Gridworks, a desktop application for exploring and cleaning tabular data. The document proposes two extensions to Gridworks: 1) browsing dcat descriptions of data catalogs within Gridworks, and 2) exporting cleaned data from Gridworks in RDF format to publish as linked data. The extensions could help governments more easily publish their data as linked open data on the web.
