  Value type “geographical object (Q618123), location (Q17334923): This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value geographical object (Q618123), location (Q17334923) (or a subclass thereof). (Help)

OppositeEdit

I do not know how to mention it, but this property seems to be the opposite of destination point (P1444).

all linear objektsEdit

this property could be used for all linear (one dimentional) objekts, i.e. routes, streets, directions, etc--Avatar6 (talk) 09:20, 13 March 2016 (UTC)

Use on 'trek' violating constraintEdit

Revision 631398949 added a constraint check enforcing the property to only be used on occurrences. This seems to go counter to the description describing it as the "starting place of this journey, flight, voyage, trek [...]", so items not necessarily associated with a temporal entity. This causes e.g. a hiking trail to be marked as possibly problematic. Is this intended behavior?

I update it with trail (Q628179) as a vàlid subclasse, because it's not only valid for the journey (occurrence (Q1190554), but also the via where the journey is done by. Amadalvarez (talk) 05:13, 7 August 2018 (UTC)
I fear we are still producing many false positives. All instances of "space probe" have a starting point and many have a destination point as well, Q61742389 as example. In general all spaceflights, all individual airplane flights and so on have a starting point. --mfb (talk) 13:27, 10 April 2019 (UTC)
