The most normative definitions I found are:


4.3.1 owl:FunctionalProperty

A functional property is a property that can have only one (unique) value y
for each instance x, i.e. there cannot be two distinct values y1 and y2
such that the pairs (x,y1) and (x,y2) are both instances of this property.
Both object properties and datatype properties can be declared as
"functional". For this purpose, OWL defines the built-in class
owl:FunctionalProperty as a special subclass of the RDF class rdf:Property.

4.3.2 owl:InverseFunctionalProperty

If a property is declared to be inverse-functional, then the object of a
property statement uniquely determines the subject (some individual). More
formally, if we state that P is an owl:InverseFunctionalProperty, then this
asserts that a value y can only be the value of P for a single instance x,
i.e. there cannot be two distinct instances x1 and x2 such that both pairs
(x1,y) and (x2,y) are instances of P.

Although as someone has pointed out, this might be a little too OWL specific
