Berners-Lee was in Washington recently to tout the project: 'In his futuristic scenario, the Semantic Web offers controlled access to American health care data, plus databases charting the location and status of rivers, underground water, forests and local vegetation, along with economic data on local industries and what they produce -- all marked up in special vocabularies. Those allow scientists to run global queries across the Web, fishing randomly for correlations that might exist between where the sick people lived, worked and played -- such as a polluted stream or industrial dump.'"
