A log is abstractly a set of [[#Event|Event]]s. [[Causeway]] accepts an arbitrary number of files, each of which contains a JSON array of events.

Event has a number of subclasses for specific events; the common structure records causality in general:

Fields:
 
-
* <code>anchor</code> :[[#Anchor|Anchor]]
 
-
* <code>trace</code> :[[#Trace|Trace]]

<var>anchor</var> records when, in what vat, this event occurred. <var>trace</var> records what caused this event, within the turn (except when the event is a Got event).
