Abstract
We propose an extension of the VOEvent format, to translate the packet from XML to JSON – with no semantic change. We also propose to use the VOEvent data model system to define three data-model Groups: “Light Curve”, “Associated Sources”, and “Followup Imaging”. This straightforward update of VOEvent simplifies the syntax and provides simple, standard representation of common astronomical datasets.
