On this techcast, Brian Sletten describes how the Semantic Web helps to define relationships between interconnected data, discusses the various tools and APIs, and how it is already being used, even without our knowledge.

Services like Friend of a Friend (FoaF), tools like RDFa, query tools like SPARQL, are discussed. If you don't know what the Semantic Web is or why it exists, Brian gives us a good overview and it's worth time listening to. Today, the US Government, wikipedia, and other systems are making data available via these mechanisms, as well as online retailers like Best Buy and Tesco.
