/**
 * Represents a <a href="http://www.w3.org/TR/owl2-syntax/#Inverse_Object_Properties" >
 * ObjectInverseOf</a> Represents the inverse of a property expression. This can be used to refer to
 * the inverse of a property, without actually naming the property. For example, consider the
 * property hasPart, the inverse property of hasPart (isPartOf) can be referred to using this
 * interface inverseOf(hasPart), which can be used in restrictions e.g. inverseOf(hasPart) some Car
 * refers to the set of things that are part of at least one car.
