JSON-LD stands for JavaScript Object Notation for Linked Data. This is a standard developed by the W3C (World Wide Web Consortium), which makes it possible to integrate structured data in a document HTML to facilitate communication between computer applications. JSON-LD markup is essentially a method of encoding information in natural language, so that it can be understood by machines.

JSON-LD markup is often used in conjunction with other standards related to structured data, such as Schema.org. Since JSON-LD uses a graph model to represent information, it can also be associated with other graph-based specifications, such as the Web Ontology Language (OWL) or the Resource Description Framework (RDF).
