Semantic Web

As the Semantic Web (sometimes called Web 3.0) emerges, the US government is pleased to be in the vanguard of this new technology space. To this end, is hosting demonstrations and documents that will help familiarize users with this new technology, and that will let citizens and developers work with the government in creating a new generation of "linked data" mash ups. now hosts a set of Resource Description Framework (RDF) documents containing triples created by converting a number of the datasets into this format, making over 6.4 billion triples of open government data available to the community. An index of all the RDF documents on is here.

The URI scheme chosen is a very simple one for the time being, designed to allow users to easily explore and extend the data. A proposal is being developed with RPI, one of the community leaders, for a new encoding of datasets converted from CSV (and other formats) to RDF. We're looking forward to a design discussion to determine the best scheme for persistent and dereferenceable government URI naming with the international community and the World Wide Web Consortium to promote international standards for persistent government data (and metadata) on the World Wide Web.

We've been watching the datasets schema space for a while now, as is very interested in adding support for our listing of over 450,000 datasets. We think this will help the major search engines create better relevance rankings of Federal government data, where many searches begin.

They shared one purpose: to create a new generation of "linked-data" applications called "mashups" that use's free public data in new and innovative ways. The U.S. government is in the vanguard of understanding and using the semantic web, which will transform the World Wide Web. Data will "talk" to one another,...

Two Days, One Great Mashup

Mashups are intriguing because you can create new stories from data that is accessible yet completely independent — multiple datasets merging in a way that was not expected," said Ryan McKeel, Digital Assets Applications Developer at the National Renewable Energy Laboratory in Golden, Colorado, whose Open Energy Initiative ( team helped build the Energy Data Mashup. "For instance, if you combine U.S. Census data with crime and voting records, you start painting a unique story that none of the data providers could have anticipated."

Ever wonder how residential energy use varies across the U.S.? By combining data from the Energy Information Administration (EIA) on with data from, the U.S. Census and, this mashup compares 7 cities with populations of roughly half a million. With differing electricity rates, median income levels, energy-related incentives and types of Smart Grid programs being introduced, cities across the country are transitioning to a new energy marketplace in unique ways.
