Linked-Data Generator (LD Generator) is Cognal Labs’ semi-automatic JSON-LD Generator, which greatly assists webmasters in generating the new JSON-LD data format (see JSON-LD.org).
On the JSON-LD website this paragraph explains the rationale for the new Linked-Data format:
“Linked Data empowers people that publish and use information on the Web. It is a way to create a network of standards-based, machine-readable data across Web sites. It allows an application to start at one piece of Linked Data, and follow embedded links to other pieces of Linked Data that are hosted on different sites across the Web. “
