JSONXMLRPC

JSONXMLRPC is a specification that defines a way to encode XML-RPC requests and responses using JSON. This allows for the use of JSON, a more lightweight and commonly used data format, in systems that traditionally rely on XML-RPC. The specification outlines how to map XML-RPC's structured data types and method calls to their JSON equivalents.

The primary goal of JSONXMLRPC is to bridge the gap between JSON-based APIs and XML-RPC services. It enables developers to leverage existing XML-RPC infrastructure while benefiting from the ease of use and performance advantages of JSON. The specification details how to represent XML-RPC's basic types, such as strings, integers, booleans, and arrays, as well as complex types like structures (objects in JSON) and fault objects.

JSONXMLRPC also addresses the process of encoding method calls and responses. A method call in XML-RPC, which includes the method name and its parameters, is translated into a JSON object. Similarly, the response, containing either a return value or a fault, is represented in JSON format according to the specification. This standardization facilitates interoperability between different systems and programming languages, making it easier to integrate JSON-centric applications with XML-RPC services without significant re-engineering.
