This document provides an overview of the Semantic Web landscape in 2010, characterized by stable core technologies complemented by emerging standards. It discusses key Semantic Web technologies like RDF, RDFS, OWL, and SPARQL, and how they enable applications not previously possible. While the Semantic Web and its technologies can be viewed differently, they represent a common, coherent set of technology standards that encourage interoperability and incremental development. The document outlines the progress of the Semantic Web community from initial experiments to larger production implementations in 2010.
