Issue 30: How to model a person's nationality
Three notions must be distinguished: Nationality as by birth/ provenance, nationality that can be acquired like citizenships, nationality as social characteristic
In practical scope.
1) by birth:
E21Person. (P98) was born - E67 Birth. (P7) took place at: E53 Place, connects to place hierarchies.
E21Person. (P98) was born - E67 Birth. (P10) falls within: E4 Period, connects to political systems as periods.
2) as citizenship:
E21Person. (P107) was member of: E74 Group
3) as social characteristics:
E21Person. (P2) has type: E55 Type
Proposal accepted. Nationality must be dealt with separately as social, legal and cultural characteristic.
