|used for waterways to build a unique object for each river|
|Tools for this tag|
The purpose of waterway relations is to have an object for each river. Common tags like references, wikipedia pages, international names, only need to be added once.
Later the waterway relations can be used to form watersheds.
|waterway=*||[river, stream, canal, drain, ditch]||Subtype of the waterway relation similar to waterway=* |
Hint: If the waterway starts as a stream and becomes larger, then use the tag of the largest waterway (e.g. river). This is purely informational, the stream members still need their own waterway=* attribute.
|name=*||*||Name of the river |
the international name tags name:en=, name:de, ... are recommended for large waterways. When a river gets multiple names (f.e. because it passes in multiple language regions), use all different names in the name tag, ordered from source to mouth, and split by hyphens. The individual sections can still get their localised name for that section.

When these roles are pointing to multipolygonal relations, the members should avoid listing giant polygons in their members.
