Linked Data (LD)

Linked Data (LD) is structured data which is linked with other data through the web. It builds upon standard web technologies, such as the Resource Description Framework (RDF) and Uniform Resource Identifiers (URIs), and uses them to share machine-readable data between computers.

LD has four requirements:

  1. Uses URIs as names for things​
  2. Uses HTTP URIs so people can look up these names​
  3. Provides useful information, using open standards such as RDF and SPARQL, when people look up a URI
  4. Includes links to other URIs so people can discover more things​
