Interface ObjectPropertySetup

All Superinterfaces:

PropertySetup

public interface ObjectPropertySetup
extends PropertySetup

Setup interface for creating new object properties. The creation is separated from the usage; for every ObjectProperty there is exactly one ObjectPropertySetup where all the characteristics of this property are defined.

To create a new ObjectProperty, define a subclass of Ontology , overwrite the Ontology.create() method, create an OntClassInfo and call OntClassInfoSetup.addObjectProperty(String).

Method Detail

setInverseOf

void setInverseOf(String inverseOf)

Set the inverse property. If an individual x is connected by this property to an individual y, then y is connected by the inverse property to x. For example, the inverse of the property a:hasFather could be the property a:fatherOf.

Parameters:

inverseOf - URI of the inverse property.

setInverseFunctional

void setInverseFunctional()

Set this property to be inverse-functional. This means that for each individual x, there can be at most one individual y such that y is connected by this property with x. For example, the property a:fatherOf is inverse-functional since each person can have only one father.

setTransitive

void setTransitive()

Set this property to be transitive. This means that if an individual x is connected to the individual y by this property, and y is connected to an individual z by this property, then x is also connected to z by this property. For example, the property a:ancestorOf is transitive: if x is an ancestor of y and y is an ancestor of z, then x is an ancestor of z.

setSymmetric

void setSymmetric()

Set this property to be symmetric. This means that if an individual x is connected to the individual y by this property, then y is also connected to x by this property. for example, the property a:sisterOf is symmetric.

A property can not be both, symmetric and asymmetric, but it can be neither of it. For example, the property a:loves is neither symmetric nor asymmetric because if one person loves another person, this does not mean that this feeling is mutual.

setAsymmetric()

setAsymmetric

void setAsymmetric()

Set this property to be asymmetric. This means that if an individual x is connected to the individual y by this property, then y cannot be connected to x by this property. for example, the property a:parentOf is asymmetric.

setSymmetric()

setReflexive

void setReflexive()

Set this property to be reflexive. This means that each individual is connected by this property to itself. For example, the property a:knows is reflexive since everybody knows themselves.

See Also:

setIrreflexive()

setIrreflexive

void setIrreflexive()

Set this property to be irreflexive. This means that no individual is connected by this property to itself. For example, the property a:marriedTo is irreflexive since nobody can be married to themselves.
