In computing, linked data describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as Hypertext Transfer Protocol|HTTP and uniform resource identifier|URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried.
Tim Berners-Lee, director of the World Wide Web Consortium, coined the term in a design note discussing issues around the Semantic Web project. However, the idea is very old and is closely related to concepts including Network model|database network models, Citation analysis|citations between scholarly articles, and Authority control|controlled headings in library catalogs.
