5.1.1 Functional relationship
Functional relationship is defined if object A has the same relationship to
two objects, than these two objects must be the same (see
Figure 2
).
Example: Zagrebačka gora is variant name of Medvednica, the same
mountain (feature) in the real world. Peak (Sljeme) is part of the Mountain
(Zagrebačka gora), and Peak (Sljeme) is part of Mountain (Medvednica),
then if Mountain (Medvednica) and Mountain (Zagrebačka gora) is the
same thing relationship is functional.

5.1.2 Inverse Functional relationship
Inverse Functional relationship
is defined if object A has relationship
to a object B, and object C has this relationship to the object B, than
object A and object C must be the same thing (see
Figure 3
).
Example: Mountain (Zagrebačka gora) has part Peak (Sljeme), and
Mountain (Medvednica) has part Peak (Sljeme), than if Mountain
(Medvednica) and Mountain (Zagrebačka gora) are the same thing
relationship is inverse functional.
