Web RDF
The document introduces the Semantic Web and Resource Description Framework (RDF). It defines the Semantic Web as a web of data that machines can understand by converting web pages into a format machines can process directly. Currently, web pages are written in HTML which machines cannot understand the meaning behind. RDF provides a standard using triples of subjects, predicates, and objects to describe resources on the web in a way that adds semantic meaning and allows machines to help find relevant information. An example is provided to illustrate using RDF triples to describe a person named Eric Miller.

- 2. What is SemanticWeb? • “The Semantic Web is a web of data, in some ways like a global database” (https://www.w3.org) • “First step is putting data on the Web in a form that machines can naturally understand, or converting it to that form, this creates what I call a Semantic Web : a web of data that can be processed directly or indirectly by machines” (Tim Berners- Lee, Weaving the web. Harper, San Fransisco. 1999)
