The term Linked Open Data refers to data that is published on the Web according to a set of best practices, as defined by Tim Berners-Lee. “Linked Open Data (LOD) are inherently interoperable and have the potential to play a key role in implementing the “I” in FAIR. They are machine-readable, based on a standard data representation (RDF – Resource Description Format) and are seen as epitomizing the ideals of open data. They offer great promise in helping to achieve a specific type of machine-executable interoperability known as semantic interoperability, which relies on linking data via common vocabularies or Knowledge Organisation Systems (KOS)”1.
An excellent example of these best practises can be found here.
