# File Type: JSON-LD

Central to the data standards is the use of [JSON-LD](https://json-ld.org/spec/latest/) (JavaScript Object Notation for Linked Data) as the data format of choice. JSON-LD is a lightweight, flexible, and web-friendly format designed to facilitate data interoperability among diverse systems. It extends the traditional JSON format by introducing the ability to contextualise data through linking, making it a compelling choice for representing and exchanging structured data in a decentralised environment like for DPI.

The use of JSON-LD promotes a semantic understanding of the data, ensuring that the exchanged information is not only machine-readable, but also meaningful and interpretable across different systems and stakeholders.
