---++ Introduction
VOEvent is the emerging International Virtual Observatory standard for distributing timely notifications of transient celestial events.  The VOEvent specification provides a method for alerting subscribers to celestial phenomena in need of rapid, often automatic, observational follow-up.  The IVOA VOEvent working group is responsible for continuing to develop the specification and for motivating the development of conforming systems, interoperable with each other and with prior community resources.

A common vision for VOEvent was forged at the first VOEvent workshop at Caltech in April 2005.  The fruits of that workshop included v1.0 of the VOEvent XML specification, as well as example packets and a schema for validating those packets.  Initial transport prototypes have been designed and deployed, and as a result actual event streams from such phenomena as gamma ray bursts are being captured as conforming VOEvent packets.

At the second VOEvent workshop, we hope to continue rapid progress on resolving thorny technical issues such as the proper semantics for specifying astronomical space-time coordinates or for specifying the classification of astronomical objects and processes.  In addition, renewed attention will be directed to understanding the science drivers common to all time domain astronomy.  VOEvent does not exist in a vacuum, and seeks to both benefit from, and provide evolutionary benefit to, prior astronomical transient event alert systems.

Or: Take the only exit out of the airport and go straight until you turn right on Kino Parkway; remain on Kino for several miles until you turn left into the main entrance of the University of Arizona; turn right on Cherry and right again into the NOAO visitors parking lot.

The sessions will take place in the <b>Main Conference Room</b>.

---++ Travel
There is a list of Tucson hotels on the Univ. of Arizona [[http://www.arizona.edu/home/visiting.php][visitor]] web pages. Click here for [[http://www.arizona.edu/home/lodging.php][Tucson Hotels]]. The Four Points Sheraton is the absolutely closest hotel, but the University Marriott is better located with respect to restaurants and shops.

There are many unique [[TucsonStuff][things to do]] while in Tucson.

----+++ <i>Schedule</i>
   * Monday and Tuesday, Dec 5-6, will consist of presentations, discussions, resolution of action items, etc., pertinent to all who are interested in sky transient astronomy.
   * Wednesday, Dec 7, a small group of projects actively planning prototype VOEvent alert networks will hold a mini-interop session.  <b>Contact seaman@noao.edu if you are interested in participating in Wednesday's session.</b>
