Linked Data

Linked data is structured data¹ that is interlinked with other data. With linked data structured information can be combined from different sources such as from different websites.

Linked data was proposed as a concept by Tim Berners-Lee. He suggested that all links between data should be URLs and be accessible via the HTTP protocols.

Linked data becomes more useful if a controlled vocabulary is used to express properties of the data.
