Linked Data is a term used to describe openly accessible and interlinked data about "Things" on the Web. Tim Berners-Lee outlined four principles of Linked Data in his Design Issues: Linked Data note, paraphrased along the following lines:
- Use URIs to identify things that you expose to the Web as resources.
- Use HTTP URIs so that people can locate and look up (dereference) these things.
- Provide useful information about the resource when its URI is dereferenced.
- Include links to other, related URIs in the exposed data as a means of improving information discovery on the Web.
