Claim

class LexData.Claim(claim: Optional[Dict[str, Any]] = None, propertyId: Optional[str] = None, value: Optional[Any] = None)

Bases: dict

Wrapper around a dict to represent a Claim

There are two types of Claim objects:

• Claims that where received from an existing entity.

• Claims that where created by the user by Claim(propertyId, value) and have not yet been uploaded to Wikidata. These are called ‘Detached Claims’, since they don’t belong to any entity. They don’t have an id nor an hash. They can be added to an entity by the function Entity.addClaims().

Currently modifications on both types of claims can’t be uploaded, except by use of the low level API call Lexeme.update_from_json().

property numeric_rank

Return the rank of the claim as integer.

Returns a integer representation of the claims rank: * 0 for normal rank * 1 for preferred rank * -1 for deprecated rank

Using this allows for easier comparing and filtering.

Example

>>> if claim.numeric_rank >= 0:
>>>     return claim.pure_value
>>> else:
>>>     logger.log("No valid value found.")
>>>     return None

Return type

int

property property

Return the id of the property of the claim. Example: “P27”

Return type

str

property_decorator

alias of builtins.property

property pure_value

Return just the ‘pure’ value, what this is depends on the type of the value:

• wikibase-entity: the id as string, including ‘L/Q/P’-prefix

• string: the string

• manolingualtext: the text as string

• quantity: the amount as float

• time: the timestamp as string in format ISO 8601

• globecoordinate: tuple of latitude and longitude as floats

Be aware that for most types this is not the full information stored in the value.

property rank

Return the rank of the claim.

The rank is one of: * “normal” * “preferred” * “deprecated”

Return type

str

property type

Return the data type of the claim as string.

Currently the following datatypes are used in Wikidata: * commonsMedia * geo-shape * globe-coordinate * math * monolingualtext * musical-notation * quantity * string * tabular-data * time * url * wikibase-form * wikibase-item * wikibase-lexeme * wikibase-property * wikibase-sense

Return type

str

property value

Return the value of the claim. The return type depends on the data type.
