We discussed this during last workshop in Paris, but this was never written down.

The idea is to add XMPP chat support to gargantext. We could then host IRC meetings inside Garg. Also, XMPP is quite large so other options are possible, eg. chatops (a bot which can interact with user, e.g. returns graph PNG upon request or send him a link of a webpage and it saves it and adds to documents).

I have set up my private server with ejabberd, it works nice so far. I have been using it for couple of months now and chat on IRC with it.

I also tested this Haskell library in another project

https://hackage.haskell.org/package/pontarius-xmpp

It seems to work fine, though it's quite a thin wrapper around the XML provided by the protocol (which doesn't have to be bad).
