0MQ: The Intelligent Transport Layer

[John Swinbank]

Hello,

Naive question: what existing Jabber infrastructure is there?

As of now, there's nothing at <http://www.voevent.org/> which refers to Jabber. Readers who want to "get started with… subscribing to streams" are directed to SkyAlert (which – correct me if I'm wrong – is all web based) or to DC3 Dakota (which only covers the simple TCP transport).

Googling finds me <http://voeventnet.caltech.edu/software/index.html>, but I'm not sure how seriously to take that: my understanding was that VOEventNet is defunct. At any rate, I tried the Java client and didn't get much sense out of it (specifying "jabber.server=moriori.cacr.caltech.edu" as per the help causes it to return "Could not connect to null:5222.: (504)").

Any other pointers appreciated.

Cheers,

John
