Scope note:
This property describes the active or passive presence of an E77 Persistent Item in an E5 Event without implying any specific role.
It connects the history of a thing with the E53 Place and E50 Date of an event. For example, an object may be the desk, now in a museum on which a treaty was signed. The presence of an immaterial thing implies the presence of at least one of its carriers.
Examples:
- Deckchair 42 (E19) was present at The sinking of the Titanic (E5)
