Definition of JSON-LD markup

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.

One of the reasons JSON-LD was developed was to facilitate communication between IT applications. By using this standardised format, machines can understand the information presented and use it to improve their own operation.

This can lead to better indexing and a higher ranking in the search engine results pages (SERP).

It can be used in conjunction with other tagging methods such as Microdata or RDFa, if necessary. However, it is generally advisable to choose one method and stick with it to avoid problems of compatibility or interpretation of the data by search engines.

10. Associations with other standards

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).
