Re: [paho-dev] MQTT <-> REST+websocket mapping

[Dave Locke <locke@xxxxxxxxxx>]

The MQTT _javascript_ client referred to
in Leif's blog post implements the MQTT specification over  WebSockets.
It is a full implementation of the MQTT spec (binary format not JSON) and
works in modern web browsers that support RFC 6455. This is something that
IBM are happy to contribute to Paho extending the set of MQTT client libraries
/ language bindings. 

It follows the the same approach as
the  WebSocket client in Mosquitto.  There are a few design points
that MQTT over WebSockets clients and servers need to be consistent on
in order for different implementations to be inter-operable. These are
captured on the wiki entry here: http://wiki.eclipse.org/Paho/Paho_Websockets
   This is something that should be fed into the MQTT OASIS standards
process. 

All the best 
Dave

Additionally, it seems that IBM is formally adding support
for MQTT over websockets to WebSphere MQ (per http://leifdavidsen.wordpress.com/2013/03/19/133/)
in a forthcoming fix pack. Not clear if this / the specification for this
will be open or not though.

You and all the others convinced me.  So, mqtt over
websocket is definitely the way to go.
I plan to start crafting something on GitHub on this issue.

So the main discussion on MQTT and WebSockets has so far
been around mosquitto and the IBM implementations - do pay attention to
the Paho wiki page that Nick linked to, and feel free to discuss here further
in an additional thread if appropriate.

Keen to ensure that the solution is something that we
can all agree on (and it does sound like we are moving in this direction!)
