Template talk:Constraint:Item

Several values

Hi, per Property talk:P245, would it be possible to have a set of possible items? Eg, to be either a person or an organisation, {{Constraint:Item|property=P107|item=Q215627|item2=Q43229}}

Thanks! --Jean-Frédéric (talk) 16:15, 28 May 2013

I agree, this would be very useful - LaddΩ chat ;) 23:31, 7 June 2013 (UTC)

+1, I was also just checking the documentation to find out how to introduce an "OR" into the logic. --Beat Estermann (talk) 17:59, 28 July 2013 (UTC)

hi, i added {{Constraint:Item|property=P107|item=Q386724|item2=Q215627|item3=Q43229}} to Property talk:P345, but on Wikidata:Database reports/Constraint violations/P345 was generated "Item main type (GND) (P107) = creative work (Q386724)" violations". Why? --Jklamo (talk) 13:52, 23 July 2013 (UTC)

Is this still actual for some properties? — Ivan A. Krestinin (talk) 18:07, 10 September 2013 (UTC)

Yes, for example for P132 (P132) see Property_talk:P964#Type_constraint:_Add_.7B.7BQ.7C262882.7D.7D.2C_.7B.7BQ.7C261023.7D.7D. Actually, I guess the same is probably true for every country, where there are more complex administrative units, which play on different levels of the hierarchy. --Zuphilip (talk) 14:32, 2 November 2013 (UTC)

@Ivan A. Krestinin: If Plant List ID (Royal Botanic Gardens, Kew) (P1070) is present then taxon rank (P105) has to be one of the following items: species (Q7432), variety (Q767728), subspecies (Q68947) or form (Q279749). So it would be great to have something like {{Constraint:Item|property=P105|oneof=Q7432, Q767728, Q68947, Q279749}}. --Succu (talk) 10:40, 23 March 2014 (UTC)

 Done, please use {{Constraint:Item|property=P105|items={{Q|7432}}, {{Q|767728}}, {{Q|68947}}, {{Q|279749}}}}. — Ivan A. Krestinin (talk) 19:38, 23 March 2014 (UTC)

How to check "should not have"?

How can I check an item to not have a certain property? For example items having ISO 3166-3 should not have ISO 3166-1. --Pabouk (talk) 12:44, 20 August 2013 (UTC)

There is no such ability now. I did not implement it because it can greatly increase visual size of constraint section on property talk pages. But if you make constraint templates more compact, I will try to implement this ability. — Ivan A. Krestinin (talk) 18:05, 10 September 2013 (UTC)

 Done, please use {{Constraint:Conflicts with}}. — Ivan A. Krestinin (talk) 19:40, 23 March 2014 (UTC)

any of some properties

Since P107 (P107) is going to be deleted or replaced, can the constraints be changed to something like "is instance of X or subclass of Y"? --AVRS (talk) 10:13, 10 September 2013 (UTC)

I think we need to find a sensible replacement for P107. --  Docu  at 16:58, 10 September 2013 (UTC)

There are {{Constraint:Type}} and {{Constraint:Value type}} for this purpose. But be warning: many items/classes are conflicting because linked using iwiki pages describe similar, but not exact the same term. For example: Nova Gorica (Q1018) is instance of en:Town and Nova Gorica (Q1018) is instance of ru:Город, but ru:Город is linked with en:City. P107 (P107) is less conflicting because it is more general and well-defined. — Ivan A. Krestinin (talk) 17:59, 10 September 2013 (UTC)

Checks

As you might have noticed, my tool, which template links to, does not work anymore. Good news: There is a much better replacement!

• For "items with property A that do not have property B", try this.
• For "items with property A that do not have property B => item C", try this.

Someone should change that in the template. Note that the new tool can be lagging up to ~10min behind. --Magnus Manske (talk) 16:35, 30 October 2013 (UTC)

Subtree of item

How to make such a constraint, for example for located in the administrative territorial entity (P131)? So we want to define not specific administrative unit but any of subunits too. --Infovarius (talk) 12:52, 13 January 2014 (UTC)

Do you mean Template:Constraint:Type? But I really doubt that we want that for located in the administrative territorial entity (P131)... --Zuphilip (talk) 17:13, 13 January 2014 (UTC)

Yes, look at constraints at Canmore ID (P718) - without that they are going wrong. --Infovarius (talk) 14:15, 14 January 2014 (UTC)

Ah, now I understand, you want to change a constraint at Property_talk:P718, namely the one with located in the administrative territorial entity (P131). That is reasonable, but I guess it is not (yet) possible. --Zuphilip (talk) 16:56, 14 January 2014 (UTC)

Wikidata query Toolserver to Toollabs

Hi just changed the url to point to to toollabs instead of the Toolserver. Looks like the syntax has changed. Someone has to do some template magic (lua/) to make a link like "CLAIM[<property id of the talk page without the P> AND NOCLAIM[<P in template without the P>]". Multichill (talk) 10:46, 13 July 2014 (UTC)

Fixed. — Ivan A. Krestinin (talk) 15:52, 13 July 2014 (UTC)

Several properties

For Property talk:P219, I need {{Constraint:Item|property=property1 OR property2}}. Please ping me if/when it is implemented. Visite fortuitement prolongée (talk) 20:55, 30 December 2014 (UTC)
