[OSM-talk] Go Map!: Mobile mapping on iOS

[Aun Johnsen]

GoMap!! is limited in its capabilities to edit relations to reduce the chance of breaking anything. Without being sure, when splitting a way that is member of a relation, both parts continue with same membership. This might give undesired results in very few relations, so I think it is a safe approach for an app that doesn’t do editing of said relations.

You can't (AFAIK) create relations, and from a quick test it seems splitting ways of a turn restriction will result in inconsistent relations (two from members in this test), i.e. if you split a way it will likely keep all (new) members in the relation regardless of relation type (i.e. routes and multipolygons will not break when splitting some of their members).
