Abstract

The most highly developed form of time dependent data publishing in the VO is that of transient event data using the established VOEvent V1.11 standard which defines the content and meaning of a standard information packet for representing, transmitting, publishing and archiving the discovery of a transient celestial event. This session will be led by Paul Harrison and will also illustrate the integration of Transient Event Data using the developing AstroGrid Simple Time Access Protocol (STAP). Examples of current event data available through the VO will be shown but participants are also encouraged to try publishing their own event data. Finally since VO publishing of time-series datasets is less mature we will also be gathering requirements of potential publishers and therefore you are welcome to bring along a short presentation (e.g. 5-10 mins) of the time-series datasets you would like to publish and any special requirements you think may apply to publishing these datasets.

Time Series Requirements

In the afternoon we had a session on creating a time series data model. Mauro López presented a report on his attempts to use the IVOA spectrum data model and SSA to serve out light curves. The conclusion was that the spectrum data model was "almost good enough" for the job, and would certainly be a good starting point to create a time series data model, and thereby not re-inventing anything unnecessarily.

We agreed to start an effort to define a time series model and an access protocol within the IVOA Data Model WG.
