Gokhan, Thanks for the example. I was able to leverage it to get the qudt units to work in owl value constraints and an earlier email from Holger to get the units to work as types.
>From Holger: Add a triple to make qudt:Unit rdfs:subClassOf rdfs:Datatype. Then I could set the range of a datatype property to Centimeters, and the form allows me to enter the literal with Centimeter as datatype. - This works great as assigning values to properties that have unit types assigned, results the correct literal type being assigned, e.g., 98.6^^unit:DegreeFahrenheit - However this solution did not work for value constraints as described in this email. I noticed in your example that you had subclasOf xsd:double and I had been concerned about the numeric type of the unit:units, because I could not find an explicit reference to xsd:double in the model, so I added a statement to subclassOf xsd:double to unit:Fahrenheit and tried unit:Fahrenheit[>90, <110], and it works. I think it will still work if I remove the <qudt:Unit rdfs:subClassOf rdfs:Datatype> suggested by Holger On Tue, Oct 5, 2010 at 6:28 PM, Gokhan Soydan <[email protected]>wrote: > Hi Arthur: Hi Arthur, > > I have added a triple to make qudt:Unit rdfs:subClassOf rdfs:Datatype.
