Re: [paho-dev] M3DA opensource java server

["andypiperuk@xxxxxxxxx" <andypiperuk@xxxxxxxxx>]

Hi Julien

This is great background information, thank you!

The Paho project definition states:

"The scope of the Paho project is to provide open source implementations of open and standard messaging protocols that support current and emerging requirements of M2M integration with Web and Enterprise middleware and applications."

It sounds like M3DA broadly fits into that scope from the perspective of Paho being the "protocols" container for the M2M initiative.

You mention the Java server contribution, are there client libraries as well and would you see them living in Mihini or in Paho?

We have a bi-weekly Paho team call, the next one being on Tuesday 19th March at 1330 UTC. I will ask Scott the project lead to invite you so that we can discuss. It might actually make sense to make the call a longer one so that we can cover your topic in enough detail and include our regular progress agenda.

Hi,

I'm Julien Vermillard from Sierra Wireless, I'm a software guy working mainly
on the server side communication stack. On a side side note I'm also a member
of the Apache Software foundation (mainly working on Apache MINA).

We started opensourcing our M3DA (Micro M2M Data Access) software stack.

The M3DA is a secure, structured and bandwidth-efficient protocol for exchanging
data between a M2M device and a server over the air.

M3DA is the protocol actually mainly used by Mihini for pushing captured data to
a M2M server.

General introduction to M3DA :
http://wiki.eclipse.org/images/1/16/M3DAPresentation.pdf

The full specification :
http://wiki.eclipse.org/Mihini/M3DA_Specification

The reference embedded client code is in the Eclipse incubating Mihini project
http://www.eclipse.org/mihini and the java server software is there:
https://github.com/SierraWireless/m3da-server

This M3DA server implementation is working, we plan to use it for the
EclipseCon Mihini tutorial.

We tried to keep the dependencies minimal and IP clean (in the Eclipse way) as
much as possible.

Some features are yet to be opened : HTTP transport and security mainly for IP
cleaning issues (we need to get rid of some dependencies) but we hope to
contribute them soon.

Since Mihini scope is more embedded M2M application framework I don't feel this
contribution could fit in.

>From what I understand of the Paho project scope, it's not tied to only MQTT as
protocol and we wonder if it would make sense for the Paho project to accept
this M3DA java server as a contribution ?
