From Relation: A role is an optional textual field describing the function of a member of the relation. For example, in North America, east indicates that a way would be posted as East on the directional plate of a route numbering shield. Or, multipolygon relation, inner and outer are used to specify whether a way forms the inner or outer part of that polygon.
