metaevent

A metaevent is a concept used in various fields, including computer science, programming, and event-driven architectures, to describe an event that is itself triggered by the occurrence of other events. Essentially, it's an event about events. This can involve tracking, processing, or reacting to a sequence, pattern, or collection of existing events.

In software development, metaevents are often employed to manage complex workflows or to aggregate information from multiple sources. For instance, a system might generate a "user session completed" metaevent only after detecting a series of individual user actions, such as login, page views, and logout events. This allows for higher-level abstractions and more sophisticated logic based on combined event data.

The purpose of a metaevent is to simplify the handling of intricate scenarios by encapsulating the logic of detecting and responding to multiple related events within a single, higher-order event. This can lead to more organized and maintainable code, as developers don't need to write repetitive logic for every possible combination of underlying events. It promotes a more declarative approach to handling asynchronous operations and system states.
