Re: Historical events

Events denoting dimensional changes of State (measures / observations) over
an entity? Periods / processes: spans while an observation in respect to a

State: countryPresident,
Event: presidentialElection,
Period / Process: presidentialRuling.

Still thinking in a more semiotical / dimensional approach.
