  15. The Semantic Web “The Semantic Web is about two things. It is about common formats for integration and combination of data drawn from diverse sources, where on the original Web mainly concentrated on the interchange of documents. It is also about language for recording how the data relates to real world objects. That allows a person, or a machine, to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing.” http://www.w3.org/2001/sw/

  16. W3C Example of RDG Syntax English Statement: "http://www.thenewpornographers.com” has a creator whose value is “Claire Puziss” RDF terms for the parts of speech: Subject: the URL, i.e. location Predicate: ”has a creator" Object: “Claire Puziss” RDF Statement: <?xml version="1.0"?> <RDF> <Description about="http://www.thenewpornographers.com/"> <title> the new pornographers | official website</title> <author>Claire Puziss</author> <homepage>http://www.thenewpornographers.com</homepage> </Description> </RDF>
