[Standards] JSON-RPC over XMPP? / XEP-0335: JSON Containers

[Christian Schudt]

Hi,

we are using a custom JSON transport protocol in order to JSON-RPC 
(http://en.wikipedia.org/wiki/JSON-RPC).

It is very similar to XEP-0009 (Jabber-RPC), but uses JSON instead of XML. 
(It's much easier to transport complex return values or parameters with 
JSON-RPC than with XML-RPC.)

Just recently I saw that there is XEP-0335: JSON Containers and I wonder if 
anybody has thought about combining it with JSON-RPC?

Something like:

<iq to="recipient.example.com" type="set" id="q1">
      <query xmlns="urn:xmpp:json-rpc">
        <json xmlns="urn:xmpp:json:0">
          { "method": "myMethodName" }
        </json>
      </query>
</iq>

Another question: It's probably unnecessary to wrap the json element into 
another element. Can urn:xmpp:json be used as direct child of IQ in order to 
signal "this is a JSON-RPC"? Like:

<iq to="recipient.example.com" type="set" id="q1">
        <json xmlns="urn:xmpp:json:0">
          { "method": "myMethodName" }
        </json>
</iq>

Well, sure it can, but I mean, are there any ideas to push this to a more 
standard way? Like adding a section in XEP-335 which says: If a json element is 
included as direct child in an IQ-set, than the JSON content SHOULD/MUST be 
conform to JSON-RPC?
