Overview

JSON (http://www.json.org) will be used to provide a lightweight data-interchange format between the web tier and any clients for requests that can currently return XML responses.

Motivation

This is the most important part of the RFC. It describes the problem domain in detail. Focusing on this will allow reviewers to fully understand why the proposed change is being made, and potentially suggest different/better ways of accomplishing the desired results. The more time we spend on understanding the problem, the better our solution will be.

The Fusion framework uses JSON in order to keep client side code simple (it much easier to work with than XML) and JSON is a more compact format so communication over the wire is more efficient.

Currently Fusion uses a web tier PHP script to convert the XML responses to JSON, but this is inefficient so we will move the generation of JSON into the server. This should further speed up the generation of the JSON, and where required we can eliminate the intermediate XML form.

Proposed Solution

This is a more detailed description of the actual changes desired. The contents of this section will vary based on the target of the RFC, be it a technical change, website change, or process change. For example, for a technical change, items such as files, XML schema changes, and API chances would be identified. For a process change, the new process would be laid out in detail. For a website change, the files affected would be listed.

Implications

This section allows discussion of the repercussions of the change, such as whether there will be any breakage in backwards compatibility, if documentation will need to be updated, etc.

Test Plan

How the proposed change will be tested, if applicable. New unit tests should be detailed here???

Funding/Resources

This section will confirm that the proposed feature has enough support to proceed. This would typically mean that the entity making the changes would put forward the RFC, but a non-developer could act as an RFC author if they are sure they have the funding to cover the change.
