Time and place

Attributes of events, not people or objects directly

Time and location belong under Events, not directly under Persons, Groups or Objects.

While the CASTEMO ontology technically allows you to attach dates and places directly to people or objects, it is more proper to attach time and place to Events. For instance:

  • a Person can have the Event of birth (labelled for instance "birth of Alexander the Great"), death, etc., which will be classified as Event of that class (e.g. "birth", "death", with SCL something like "life-cycle event"), and will have its time and place (and potentially other circumstances) attached;
  • a manuscript (Object), or text (Territory) or textual version (Resource) can have the event of composition, which will again have its time and place.

This is ontologically more appropriate, if you think what time and place really describes, but also practically, for instance if you need to treat more complicated spatial or temporal relations such as range (some time between year 1250 and 1350) or uncertainty.

Such Event will be attached to the entity through a property, e.g.:

P Alexander the Great - PROP - C event of birth - E birth of Alexander the Great
