---+++ Agenda:
*Focus Area 1*
What are the purposes of a system that exchanges information about immediate astronomical events (VOEvents). How and why should we search and subscribe to such a feed? How would messages be generated from one telescope and be used to drive another telescope? What can be done with a federation of VOEvent data from different sources?
(eg searching LIGO/GRB databases? Xray flash followed by optical transient?)

*Focus Area 2*
What is the semantic structure of a VOEvent message? Is the "Who, When, Where, What, How" paradigm the correct one? How should existing schema be integrated? Please try to read the existing draft semantics:
http://www.ivoa.net/internal/IVOA/IvoaVOEvent/VOEvent-0.3.htm

*Focus Area 3*
How can we make a set of adjectives ("ontology") that can be used to describe a VOEvent (eg supernova, planetary volcano, magnitude increase, etc)

*Focus Area 4*
How can we build a system that exchanges VOEvent messages for the purposes that we uncover in Focus Area 1? What are the softeare components, protocols, and messages? What is the security infrastructure (if any)? Who can create and inject messages into the system? Who can read, subscribe, and query the messages?
