VOEvent
Activities since Trieste have focused on discussions and preparations for VOEvent v2.0. Intent is to move this to proposed recommendation stage in coordination with the VOEvent IV workshop at UCSC at the end of April 2009.
VOEvent v2.0 will include support for the representation of time series and orbital elements, for improved references to external URIs of various types, for explicitly referencing external schemata in support of non-native event streams, and for a controlled vocabular(ies) based on the excellent work of the semantics WG. In addition, the WG is investigating different options for authentication via digital signing technologies.
As separate initiatives that will likely result in distinct proposed recommendations, the WG is discussing the Simple Event Access Protocol (SEAP) and Registry support for servers serving streams of scientifically related VOEvent packets. These efforts are not currently scheduled, but one would anticipate significant progress over roughly the next year.
The VOEvent WG continues to pursue collaboration with several extra-IVOA entities, particularly including the internationally sited Heterogeneous Telescope Networks (HTN) consortium and NASA's Gamma-ray bursts Coordinates Network (GCN). We are aggressively pursuing additional event streams, for instance, events resulting from the upcoming Dark Energy Survey to be conducted with the very wide field DECam at the CTIO 4m Blanco telescope.
In addition to VOEvent sessions and joint sessions at the Baltimore Interop, WG personnel will be presenting at the ADASS Sky/WWT tutorial and at the ADASS BOF, "Architectures for Time Domain Astronomy". Several ADASS contributions derive from VOEvent technologies and projects.
