Duration Field

Overview

A duration of time. We follow the definition of XML Schema duration datatype directly and that definition is implicitly inlined here. Read more in Table Schema Standard.

Example

from frictionless import Schema, extract, fields

data = [['name'], ['P1Y']]
rows = extract(data, schema=Schema(fields=[fields.DurationField(name='name')]))
print(rows)

{'memory': [{'name': isodate.duration.Duration(0, 0, 0, years=1, months=0)}]}
