Available languages — Super-Relation
· čeština · English

A super-relation is a relation that contains other relations. Relations have initially been created to contain nodes, ways or areas and combinations thereof.

A super-relation is referred to as a 'parent' in Osmosis. The hierarchical structure of super- and sub-relations is also called a 'nested relation'.


Nested relations are virtually undocumented and rarely used but still there is an effort to process them.

Examples of a super-relation is the Great Lakes which contains relations of each of its 5 lakes.
