Identity data standards have transitioned from XML to JSON and JSON-LD, driven by the need for more flexibility and simplicity in web development and API communications. XML, once dominant, provided a structured and predictable framework for data exchange but was cumbersome due to its verbosity and schema dependency. JSON emerged as a lightweight, human-readable alternative, facilitating faster data transmission and easier integration into modern web applications, which has become the standard for RESTful APIs and identity verification processes. JSON-LD further enhances this by adding semantic meaning and context, allowing data to be linked and understood in broader contexts, which is essential for tasks like Reusable KYC and cross-organizational data sharing. Didit leverages these advanced standards in its AI-native platform, offering flexible APIs and orchestrated workflows for identity verification tasks, ensuring efficient and secure data handling. This evolution in data standards has significantly improved interoperability and digital trust, enabling businesses to perform identity verification with enhanced fraud prevention, compliance, and user experience capabilities.
