Chapter 5. Richer Metadata and RDF > Resource Description Framework

5.2. Resource Description Framework

This system of defining everything with URIs, and using this to describe the relationships between things, has been formalized in a system known as the Resource Description Framework (RDF). In this section, we'll look at enough RDF to give us a head start on the rest of the book. For a much deeper insight into RDF, take a look at Shelley Powers' Practical RDF (O'Reilly).

Because RDF is quite abstract — its ability to be written in different ways notwithstanding — in this chapter we are going to look at what the RDF developers call the "data model," which we can call "the really simple version, in pictures."
