Library with Python models derived from the page package world.opensemantic.characteristics.quantitative

Quantities and units generated from QUDT. pint mapping was done with support from ucumvert

Usage

from opensemantic.characteristics.quantitative import (
    Length, LengthUnit, Width, Area, AreaUnit, QuantityValue,
)

# Create typed quantity values
length = Length(value=1.0, unit=LengthUnit.meter)
width = Width(value=200, unit=LengthUnit.milli_meter)

# Arithmetic — units are tracked automatically via pint
area = length * width
print(area.value, area.unit.name)  # 200000.0 milli_meter_squared
assert isinstance(area, Area)

# Unit conversion
area_cm2 = area.to_unit(AreaUnit.centi_meter_squared)
print(area_cm2.value)  # 2000.0
assert area == area_cm2  # physical equality across units

# Addition with automatic unit conversion
l1 = Length(value=1.0, unit=LengthUnit.milli_meter)
l2 = Length(value=1.0, unit=LengthUnit.meter)
print((l1 + l2).value)  # 1.001 (in meters)

# pint interop: round-trip to/from pint.Quantity
q_pint = l1.to_pint()                    # -> 1.0 millimeter
restored = QuantityValue.from_pint(q_pint)  # -> Length(1.0, milli_meter)
assert l1 == restored

# JSON serialization (via oold's unified API)
print(l1.to_json())
# {'type': ['Category:OSWee9c7e5c...'], 'value': 1.0, 'unit': 'Item:OSWf101d25e...'}

TODO: Unit Name Conflicts in _collection.py

18 unit member names appear in multiple *Unit enum classes with different OSW IDs. The first occurrence goes into _collection.py; conflicting entries remain hardcoded in _model.py. These likely stem from upstream QUDT modeling where the same unit name maps to different physical quantities.

Name	Classes (conflicting OSW IDs)
day	TimeUnit vs HydraulicPermeabilityUnit
kilo_newton	ForceUnit vs TorquePerLengthUnit
kilo_newton_per_meter	EnergyPerAreaUnit vs ForcePerLengthUnit
liter_per_meter_squared_per_second	VolumetricFluxUnit vs VentilationRatePerFloorAreaUnit
meter	LengthUnit vs AreaPerLengthUnit vs VolumePerUnitAreaUnit
