VOEvent network operations
• Entering new mission-critical phase– Unexplored territories– Commitment to resolving problems
• Teamwork will be (re)emphasized– More specific roles
• Once turned on, it stays on – forever– Dedicated resources, many 9’s reliability– User support 24/7/365– Capacity must scale up to LSST levels

V2.0 – Time Series +
• SimpleTimeSeries in <What>
• STC Orbital Elements in <WhereWhen>
• More general external <References>
• Datatypes for <Param>
• Benefit from vocabularies
• Tweaks and small enhancements
• Ruggedize schema while keeping simple

The Tao of VOEvent
• High level• Light weight• Flexible• Low cost of entry
![Page 11: VOEvent Working Group](https://reader035.vdocument.in/reader035/viewer/2022062310/568166ef550346895ddb47e3/html5/thumbnails/11.jpg)
VOEvent
• Low latency & rich semantics
• Human readable & computer parse-able
• Robotic autonomy & historical telegrams
• Push paradigm vs. SEAP for query
VOEvent dualism
All design choices are made under dynamic tension
