The document discusses the evolution of the web from a "Web of Documents" to a "Semantic Web." It argues that while the vision of a Semantic Web proposed in 2001 has yet to be fully realized, the pieces are falling into place. Examples of linked open data projects show how structured data from sources like Wikipedia, the BBC, and government data is being interconnected using semantic web technologies. The use of semantics on the web brings value by sometimes solving narrow problems and linking data beyond specific applications.
