Data properties link individuals to data values.
A set of instances connected to the property is called a property extension.
Contents
SubDataPropertyOf axioms count
This axiom says that a property is a subproperty of another property. It also means that the instances of the subproperty are subsets to the property extension of the second property.
Equivalent data properties axioms count
Equivalent property axioms exist when two properties have the same property extension.
Disjoint data properties axioms count
Two properties are disjoint when they don't have individuals in common.
Functional data property axioms count
A functional property is a property which can only have one value. E.g. a woman can have at most one husband.
Data property domain axioms count
The domain links a property to a class description.
There can be more than one domain for a property.
Data Property range axioms count
The range links the property to either a class description or a data range.
There can be more than one range for a property.
