Property

class Property(*args, **kwargs)[source]

Bases: Entity

Binary relationship.

Parameters:

iri – IRI.
range – Datatype.

datatype_class: alias of PropertyDatatype

datatype: ClassVar[PropertyDatatype] = PropertyDatatype(): Datatype associated with this value class.

template_class: alias of PropertyTemplate

variable_class: alias of PropertyVariable

__init__(iri: VTPropertyContent, range: VTDatatype | None = None) → None[source]

property range: Datatype | None: The range of property.

get_range(default: Datatype | None = None) → Datatype | None[source]

Gets the range of property.

If range is None, returns default.

Parameters:: default – Default range.
Returns:: Datatype.

no_value() → NoValueSnak[source]

Constructs a no-value snak from property.

Returns:: No-value snak.

some_value() → SomeValueSnak[source]

Constructs a some-value snak from property.

Returns:: Some-value snak.

class PropertyTemplate(*args, **kwargs)[source]

Bases: EntityTemplate

Property template.

Parameters:

iri – IRI, IRI template, or IRI variable.
range – Datatype or datatype variable.

object_class: alias of Property

__init__(iri: VT_IRI, range: VTDatatype | None = None) → None[source]

property range: DatatypeVariable | Datatype | None: The range of property template.

get_range(default: DatatypeVariable | Datatype | None = None) → DatatypeVariable | Datatype | None[source]

Gets the range of property template.

If range is None, returns default.

Parameters:: default – Default range.
Returns:: Datatype or datatype variable.

no_value() → NoValueSnakTemplate[source]

Constructs a no-value snak template from property template.

Returns:: No-value snak template.

some_value() → SomeValueSnakTemplate[source]

Constructs a some-value snak template from property template.

Returns:: Some-value snak template.

class PropertyVariable(name: str, variable_class: type[Variable] | type[Term] | None = None)[source]

Bases: EntityVariable

Property variable.

Parameters:: name – Name.

object_class: alias of Property

no_value() → NoValueSnakTemplate[source]

Constructs a no-value snak template from property variable.

Returns:: No-value snak template.

some_value() → SomeValueSnakTemplate[source]

Constructs a some-value snak template from property variable.

Returns:: Some-value snak template.
