A creation_date attribute is used to define the moment when an entity was created or came into existence. This allows Veezoo to interpret user questions involving the age since an entity was created.

Example: A kb.Company class may have a creation_date attribute. When the user asks "how old is our company", Veezoo should compute the age based on the creation_date.


To use the creation_date attribute, you need to define it in your class as shown in the example below.

import: [

kb {
class Company {
name.en: "Company"

creation_date: Incorporation_Date


date Incorporation_Date {
name.en: "Incorporation Date"

datetime_format: DayFormat

sql: "${COMPANIES.incorporation_date}"
