The Simple Power of the Link
The document discusses the core concepts of the web and semantic web. It explains how linked data uses semantic web standards to identify things with URIs and describe them using attributes. An example is given describing a spacecraft using its URI and attributes like name, mass, launch date, site, and coordinates. Links connect related concepts like the spacecraft and its launch.
