  12. 12. The Web of Data• A global network of linked statements• A place where anyone can say anything about anything• A vast collection of machine-readable knowledge (and opinion)• Statements are linked, and links are qualified 12
  13. 13. • Linked Data is about publishing and consuming data using international data standards• Based on 20 year old idea• A system of linked information systems 13

Linked Data Improves Discoverability & AccessLinked Data - refers to a set of best practices for publishing andinterlinking structured data for access by both humans andmachines via the use of the RDF family of syntaxes (e.g., RDF/XML, N3, Turtle and N-Triples) and HTTP URIs.Linked Data can be published by an person or organizationbehind the firewall or on the public Web. If Linked Data ispublished on the public Web, it is generally called Linked OpenData. - W3C Linked Data Glossary: 18
