Class Property (2.18.0)

Property(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Defines properties that can be part of the entity type.


name str
The name of the property. Follows the same guidelines as the EntityType name.
value_type str
A reference to the value type of the property. This type is subject to the same conventions as the Entity.base_types field.
Occurrence type limits the number of instances an entity type appears in the document.
Any additional metadata about the property can be added here.




Types of occurrences of the entity type in the document. This represents the number of instances of instances of an entity, not number of mentions of an entity. For example, a bank statement may only have one account_number, but this account number may be mentioned in several places on the document. In this case the 'account_number' would be considered a REQUIRED_ONCE entity type. If, on the other hand, we expect a bank statement to contain the status of multiple different accounts for the customers, the occurrence type will be set to REQUIRED_MULTIPLE.

Values: OCCURRENCE_TYPE_UNSPECIFIED (0): Unspecified occurrence type. OPTIONAL_ONCE (1): There will be zero or one instance of this entity type. The same entity instance may be mentioned multiple times. OPTIONAL_MULTIPLE (2): The entity type will appear zero or multiple times. REQUIRED_ONCE (3): The entity type will only appear exactly once. The same entity instance may be mentioned multiple times. REQUIRED_MULTIPLE (4): The entity type will appear once or more times.
