This document provides an introduction to linked data and RDF. It discusses: 1. The principles of linked data, which involve using URIs to identify things and including links to other related resources. 2. The goals of linked data, which are to transfer information between machines without loss of meaning by identifying data on the web using shared vocabularies and RDF. 3. An overview of RDF, which structures data as subject-predicate-object triples and can be serialized in formats like RDF/XML and Turtle to represent typed links between resources.
