Returns a handle to a property.
If input property is zero, the handle will point to the first property having cardinality restriction to the class.
else it will point to next property with known restriction
If all properties are past (or no relevant properties are found), the function will return 0.
minCard and maxCard will contain restrictions for returned property
Note: this function does not return inherited restrictions.

Property owlClass
Size: 64 bit / 8 byte (value)
This attribute represents a handle to the class. The term owl is comming from W3C, the classes follow the expression power of Semantic Web concepts, therefore classes support multiple inheritance. Technically classes can also be distributed over different resources, however for this the parametric library is required as an extension on the basic Geometry Kernel API.
Property rdfProperty
Size: 64 bit / 8 byte (value)
This attribute represents a handle to the property, this can be either a datatype property (attribute), an object property (relation) or non-defined property. The handle will be static during the life-time of the model, when the model (or part of it) is saved and opened again, the handle will most probably be different.
Property minCard
Size: 32 bit / 4 byte (reference)
The minimum cardinality (i.e. number of elements) of this property.
Property maxCard
Size: 32 bit / 4 byte (reference)
The maximum cardinality (i.e. number of elements) of this property.
