Event

An Event is a temporal occurrence where things undergo state change at identifiable points in time.

• AKA: Occurrence, Happening, Incident, Temporal Marker.
• Context:
  • It can typically involve Entities undergoing state transitions.
  • It can typically occur at Temporal Locations with time coordinates.
  • It can typically manifest in Spatial Locations within space coordinates.
  • It can typically exhibit Causal Relationships with other events.
  • It can typically possess Event Durations from instantaneous to extended.
  • ...
  • It can often trigger Subsequent Events through causal chains.
  • It can often require Precondition Events via temporal dependencies.
  • It can often produce Observable Effects in physical systems.
  • It can often be detected through Event Indicators or event signals.
  • ...
  • It can range from being a Deterministic Event to being a Probabilistic Event, depending on its predictability.
  • It can range from being an Atomic Event to being a Composite Event, depending on its structural complexity.
  • It can range from being a Local Event to being a Global Event, depending on its spatial scope.
  • It can range from being an Instantaneous Event to being a Durative Event, depending on its temporal extent.
  • It can range from being a Physical Event to being an Abstract Event, depending on its manifestation type.
  • ...
  • It can be observed by Sensor Systems through measurement.
  • It can be recorded in Event Logs using timestamps.
  • It can be analyzed by Event Processing Systems for pattern detection.
  • It can be simulated in Computational Models for prediction.
  • ...
• Example(s):
  • Natural Events, such as:
    • Weather Events like storm, earthquake, volcanic eruption.
    • Astronomical Events like eclipse, meteor shower, supernova.
    • Biological Events like birth, death, mutation.
  • System Events, such as:
    • Computational Events like program execution, error occurrence, data update.
    • Network Events like connection establishment, packet transmission, security breach.
    • User Interface Events like click, keystroke, gesture.
  • Social Events, such as:
    • Organizational Events like meeting, decision, milestone achievement.
    • Economic Events like transaction, market crash, product launch.
    • Political Events like election, treaty signing, policy change.
  • Process-Related Events, such as:
    • Activity Start Events marking activity initiation.
    • Task Completion Events marking goal achievement.
    • State Transition Events marking process phase change.
  • Measurement Events, such as:
    • Sensor Events capturing environmental data.
    • Threshold Events when values exceed limits.
    • Detection Events identifying pattern occurrences.
  • ...
• Counter-Example(s):
  • Entity, which represents things that persist rather than occur.
  • Property, which describes characteristics rather than occurrences.
  • Relationship, which connects things rather than marking changes.
  • State, which represents conditions rather than transitions.
  • Pattern, which describes regularities rather than specific occurrences.
