VOEvent defines the content and meaning of a standard
information packet for representing, transmitting, publishing and archiving
information about a transient celestial event, with the implication that timely
follow-up is of interest. The objective is to motivate the observation of
targets-of-opportunity, to drive robotic telescopes, to trigger archive
searches, and to alert the community. VOEvent is focused on the reporting of
photon events, but events mediated by disparate phenomena such as neutrinos,
gravitational waves, and solar or atmospheric particle bursts may also be
reported.

Structured data is used, rather than natural language, so that automated
systems can effectively interpret VOEvent packets. Each packet may contain zero
or more of the “who, what, where, when &amp; how” of a detected event, but in
addition, may contain a hypothesis (a “why”) regarding the nature of the
underlying physical cause of the event.

Citations to previous VOEvents may be used to place each event in its correct
context. Proper curation is encouraged throughout each event's life cycle from
discovery through successive follow-ups.

VOEvent packets gain persistent identifiers and are typically stored in
databases reached via registries. VOEvent packets may therefore reference other
packets in various ways. Packets are encouraged to be small and to be processed
quickly. This standard does not define a transport layer or the design of
clients, repositories, publishers or brokers; it does not cover policy issues
such as who can publish, who can build a registry of events, who can subscribe
to a particular registry, nor the intellectual property issues.
