Representation of passport information

Is there anywhere I could get guidance on how a passport (or social
security number or similar) item would be represented in the schema?
Specifically this passport will be linked to a person. So I guess my
question is two fold:
1. How do I represent the passport?
2. How do I link the passport to a Person <>?
Kind regards,
