Events denoting dimensional changes of State (measures / observations) over
an entity? Periods / processes: spans while an observation in respect to a
(dimensional) concept remains the same?
State: countryPresident,
Event: presidentialElection,

Still thinking in a more semiotical / dimensional approach.
