Adding value restrictions on data properties

[Lindsay]

Hi all! I'm trying to create a class called high energy instrument that is equivalent to an instrument that has a power greater than a certain value.

I'm using bfo and common core ontologies. This what I have so far.

class HighEnergyInstrument():
            equivalent_to = [SatelliteInstrument &has_quality.some(
                              Power & is_measured_by_ratio.some(
                               RatioMeasurementInformationContentEntity & inheres_in.some(
                                InformationBearingEntity & has_integer_value.min(30,)
                                  & uses_measurement_unit.some(units.WattMeasurementUnit)
                              )))]
       

in protege I would use the string '30'^^xsd:integer but I'm not sure if there's something different in owlready2.

Thanks in advance!

Hello,

I think you should use constrained datatypes. For example, has_integer_value.min(30,) should be written:

        ConstrainedDatatype(int, min_inclusive = 30)

Constrained datatypes can be used as a class, e.g. in a some() or only() statement.

That's exactly what I was looking for. Thanks!
