Data type	Item
Domain	public transport stop (Q548662)
Allowed values	items with instance of (P31) → station (Q719456) (or its children, such as railway station (Q55488)) (note: this should be moved to the property statements)
Usage notes	This property replaces usages of "direction" (P560) whose values are "instance of" (P31) "station" (Q719456) or its subclasses. Uses of P560 when their values are of type "direction" (Q2151613) should not be replaced. Set to 'novalue' for loop/circular lines.

mass paths

I'm using this for mass paths, because it helps to organize them by their destination. I'm getting a warning about it, though, but it would be great if it was "legal" to use the statement for mass paths as well. If there is an alternative, I'd be happy to learn about it. A.-K. D.
