The Semantic Web is an international effort to bring machine-readable data to the web called linked data and was started by Sir Tim Berners-Lee, the inventor of the world-wide-web. Linked Data is based on a RDF (Resource Description Framework) graphs made up a series of statements, called triples, that take the form subject - predicate - object.
A relationship between the subject and object is called a property.
A predicate must be an IRI.
