triplemodel.terms.typed_literal

Per-object XSD datatypes for multi-valued literal fields.

class triplemodel.terms.typed_literal.TypedLiteral(value, datatype=None)[source]

Bases: object

One RDF literal value with its own XSD (or custom) datatype IRI.

Use as the element type of set[TypedLiteral] or list[TypedLiteral] when several objects on one predicate may carry different ^^datatype IRIs. Field-level literal_datatype= applies one datatype to every object; this type preserves each graph literal’s datatype independently.

Parameters:

value (str)
datatype (str | None)

value: str

datatype: str | None = None

__init__(value, datatype=None)[source]

Parameters:

value (str | int | float | bool)
datatype (str | None)

Return type:

None

classmethod from_literal(term)[source]

Build from a pyoxigraph Literal (language tags are not preserved).

Return type:: TypedLiteral
Parameters:: term (Literal)

to_literal()[source]

Serialize to a pyoxigraph Literal.

Return type:: Literal
