Date of Birth
- Value statement: The date of birth of a person is a generally useful piece of contextual information about the person. This can also be used as a minimum disambiguation triple for people as it significantly reduces the number of entities in the search space (although its worth noting the distribution of birthdays across all people is not uniform)
- Definition: “The official date of birth of this person, as evidenced by a resource officially owned by, operated by, or directly affiliated with the person stating their birth date. Official documentation, such as a birth certificate, may also provide evidence.“
- Tooltip definition of the predicate: “The birth date of this person”
- Type of value: Date
- For enums - all possible values: N/A
- # of accepted values: One
- Inverse Properties and Name: N/A
Examples of proper use:
- ‘Mark Zuckerberg’ → ‘Date of Birth’ → ‘5/14/1984’, citation: https://www.facebook.com/zuck/about_contact_and_basic_info. This citation points to an official page for Mark Zuckerberg (as further evidenced by Facebook’s ‘blue check’ on the profile) that states Mark Zuckerberg’s birthday.
Examples of improper use:
- ‘Apple’ → ‘Date of Birth’ → ‘4/1/1976’ is incorrect, as Apple does not have the value “is a”–> ‘Person’. This date is the founding date of the company and should be include in ‘Founded Date’.
- Usage in other schemas:
- Constraints: Entity should have value ‘is a’ → ‘Person’
- Masculine/Feminine Form: N/A
- Restrictions (ie PII concerns): N/A
