International Virtual Observatory Alliance
The VOEvent standard has been well taken up by the community since 2006, and there have been thousands of events in this format. Now there is interest in new schema for VOEvent 2.0, specifically to be able to put small tables, time series, ephemeris etc into the packet. We also discuss the use of linking to connect to complex data, and ask if any extra structure is actually needed, or if linking can always be the answer. We present some use cases for such extra structure, consider representing these within the current VOEvent structure, and suggest a simple table extension to VOEvent, based on an existing IVOA Recommendation, that would represent all the use cases in a simple way.
