XMPP as VOEvent transport

[John Swinbank]

Dear all, but particularly Jean-Paul,

A new thread on this, since I don’t want the discussion of VTP to turn into a more general-purpose discussion of how one could or should transport VOEvents. However, I was interested to hear that Svom is pressing forwards with XMPP as a distribution mechanism: I’m aware of that being discussed several years ago, but hadn’t seen any news in some time (I’m out of the loop; sorry).

I’d be curious to know what the latest status of this is. Is there code available? A “getting started” document describing how it works? Any thoughts on scaling to large numbers of events, or large event packet sizes, or bulk distribution? Does it help address issues regarding event authenticity?

VTP is useful as a minimal baseline, but I have reservations about it, particularly in terms of scalability, and I’d love an update on other work in this area.

Cheers,

John
