Draft is document in place, http://www.ivoa.net/internal/IVOA/IvoaVOEvent/VOEvent-0.3.htm Objective is to use schemas as building blocks -- IVOA resource, RTML, etc... (2) Twiki page is here http://www.ivoa.net/twiki/bin/view/IVOA/IvoaVOEvent Mailing list archive is here http://www.ivoa.net/forum/voevent/ (waiting for links from IVOA front pages) (3) Working to interoperate existing alert systems -- IAU Bureau of Telegrams -- Gamma-ray Burst Coordinate Network (GCN) -- RTML - Remote Telescope Markup Language -- Astronomer's Telegram Question: What other alert systems are out there? (4) Planning for a 2-day workshop in Pasadena in March or April. All IVOA exec are invited. Dates still fluid. (5) We need an ontology of event types: it would contain for example Comets, Supernovae, Novae, Outbursts Of Unusual Variable Stars, Features On Planetary Surfaces.
