Event

class nominal.Event

A time-based annotation on one or more assets.

Events flag a moment or interval: a fault, a phase boundary, an anomaly. Created from a client:

e = c.createEvent("<asset rid>", "overspeed", ...
                  Type="error", Duration=seconds(10));

Events attach to assets, not to runs or datasets. A run shows the events whose time falls within it.
