VOEvent is a standardized language used to report observations of astronomical events; it was officially adopted〔 〕 in 2006 by the International Virtual Observatory Alliance (IVOA). Though most VOEvent messages currently issued are related to supernovae, gravitational microlensing, and gamma-ray bursts, they are intended to be general enough to describe all types of observations of astronomical events, including gravitational wave events. Messages are written in XML, providing a structured metadata description of both the observations and the inferences derived from those observations. The rapid dissemination of event data with a formalized language was the original impetus〔 〕 for the creation of VOEvents and the network (now called (VOEventNet )) used to transport the messages; indeed VOEvent messages are designed to be compact and quickly transmittable over the internet. The VOEvent language (which is codified in an XML schema) continues to evolve; the (latest version is 2.0 ). == History == VOEvent builds upon previous generic publishing schemes such as International Astronomical Union Central Bureau for Astronomical Telegrams (IAUCs and CBETs) and the Astronomer's Telegrams (ATELs). The principal difference is that VOEvent messages are intended to be automatically parsed and filtered whereas ATELs and IAUCs are intended to be read by humans. The scope of VOEvent is informed by several other messaging schemes used to facilitate rapid discovery announcements for specialized sub-fields of astronomy (such as OGLE microlensing alerts and Supernova Early Warning System). The closest ancestors of VOEvent are The Telescope Alert Operation Network System (TALON) and the Gamma Ray Burst Coordinates Network (GCN) messages, used extensively by the gamma-ray burst community. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VOEvent」の詳細全文を読む スポンサード リンク
