Subproperties
- in addition to subclasses,
RDFS supports subproperties
- defining
father
and
mother
as subproperties of
parent
allows us define our data using
mother
and
father,
but then query on either
mother,
father,
or parent
- another common usage is to model roles, e.g.
teamLeader
is a subproperty of
teamMember
