+Feature: Linking of places
+    Tests for correctly determining linked places
+
+    Scenario: Only address-describing places can be linked
+        Given the scene way-area-with-center
+        And the places
+         | osm  | class   | type   | name  | geometry |
+         | R13  | landuse | forest | Garbo | :area |
+         | N256 | natural | peak   | Garbo | :inner-C |
+        When importing
+        Then placex contains
+         | object  | linked_place_id |
+         | R13     | - |
+         | N256    | - |
+
+    Scenario: Waterways are linked when in waterway relations
+        Given the scene split-road
+        And the places
+         | osm | class    | type  | name  | geometry |
+         | W1  | waterway | river | Rhein | :w-2 |

+         | R23 | waterway | river | Limmat| :w-4a |
+        And the relations
+         | id | members                          | tags+type |
+         | 13 | R23:tributary,W1,W2:main_stream  | waterway |

+         | R2     | - |
+
+    Scenario: Empty waterway relations are handled correctly
+        Given the scene split-road
+        And the places
+         | osm | class    | type  | name  | geometry |
+         | R1  | waterway | river | Rhein | :w-1 + :w-2 + :w-3 |

+        Given the scene split-road
+        And the places
+         | osm | class    | type     | name  | geometry |

+          |  0 | R |
+          |  1 | W |
+
+    Scenario: Side streams are linked only when they have the same name
+        Given the scene split-road
+        And the places
+         | osm | class    | type  | name   | geometry |
