Introduction

The Resource Description Framework (RDF) is a W3C standard for modelling linked data. The purpose of linked data is to enable data from different sources to be easily and meaningfully linked together, thereby making it more useful.

Triples

RDF represents data as simple sentences called “triples”. A triple is made up of a subject, predicate and object.

A triple can be visualized as a graph, where ovals represent the subject or object of the sentence, while arrows represent the predicates (i.e. the relationships).
