This proposal entails the use JavaScript Object Notation (JSON) to produce human readable and web technology-friendly encodings of FIX messages.

JavaScript Object Notation (JSON) is the lingua franca for communications between web browsers and the services that power them. JSON Encoding of FIX supports the development of web applications that require FIX semantics. It is not optimized for low latency, but rather for human readability and interoperability between web services and web languages.

Discussion on JSON encoding of FIX may be found on the FPL Discussion Forum in the General Q&A category using the tag “json”.

More information on the work from the JSON Encoding Working Group can be found here.

The proposed technical standard for Encoding FIX using JavaScript Object Notation (JSON) is following the technical standards review process described in the document found here.
