Scope note:
This property links an E67 Birth event to an E21 Person in the role of biological father.
Note that biological fathers are not seen as necessary participants in the Birth, whereas birth-giving mothers are (see P96 by mother (gave birth)). The Person being born is linked to the Birth with the property P98 brought into life (was born).
This is not intended for use with general natural history material, only people. There is no explicit method for modelling conception and gestation except by using extensions.
A Birth event is normally (but not always) associated with one biological father.
Examples:
- King George VI (E21) was father for the birth of Queen Elizabeth II (E67)
In First Order Logic:
P97(x,y) ⊃ E67(x)
P97(x,y) ⊃ E21(y)
