Subproperty edit

Shouldn't this property be a subproperty of elevation above sea level (P2044)? Lymantria (talk) 06:37, 23 June 2016 (UTC)Reply

Double constraint edit

Hi,

Right now, there is two time more-or-less the same constraint :

which is very narrow and limitative to lighthouses using instance of (P31) = lighthouse (Q39715)

and

which is the same idea but more flexible and allow to check the lighthouses not using instance of (P31) = lighthouse (Q39715).

I removed the first but Esquilo reverted me and asked for explanations here. Here they are, I can give more if needed.

  • It's different. The problem with the type constraint is that some applications use just that and others don't support it fully. Is there a lighthouse where you were unhappy with the result?
