Hello,

I'm going to implement JSON-PRC web service. I need specifications for this. So far I had found only one resource that can be called as real specifications:

• JSON-RPC 1.0 http://json-rpc.org/wiki/specification
• Proposal of JSON-PRC 2.0: http://groups.google.com/group/json-rpc/web/json-rpc-2-0 (why is it on google groups?)

However I've seen that JavaScript frameworks like Dojo actively use JSON-RPC SMD

• Service Mapping Description proposal

But it requires JSON Schema specifications, but it redirects to incorrect URL as reference. So far I had found following:

• http://tools.ietf.org/html/draft-zyp-json-schema-02

And it is still draft...

Can anybody point me to some actual specifications... At least something official updated? Because it looks like that implementing JSON-RPC 1.0 as is may be not enough, at least for frameworks like Dojo. Or am I wrong?

Questions:

• Would implementation of JSON-RPC 1.0 specifications be enough to provide JSON-RPC service for most of modern clients, and how many clients there (if at-all) that actually support beyond JSON-RPC 1.0 capabilities (SMD, Schema, 2.0)?

  Because it looks like that JSON-RPC 1.0 is only one that has official specifications (and not draft)

• If I should implement SMD, or it is recommended can somebody point to official, most recent specifications of Json Schema and Service Mapping Description or links I found are really "the specifications?"
• Are JSON-RPC 2.0, SMD and JSON-Schema drafts stable enough to implement them?

Note: do not suggest existing JSON-RPC service implementations.

Anybody?
