Constraints

Hi @Andreasmperu: many thanks for creating this. The constraints may need a bit more thinking about though.

If we take the original use-case as an example,

⟨ Spain (Q29) ⟩ has list (P2354) [[Special:Search/Property:has list (P2354)|Search]] ⟨ list of cities of Spain (Q189098) ⟩
of (P642) [[Special:Search/Property:of (P642)|Search]] ⟨ municipality (Q15284) ⟩

then in general:

• the target may not necessarily be single, since "Spain" may also have other notable lists related to it, eg a list of autonomous community of Spain (Q10742)
• the target may not necessarily be unique, since it is possible that it might also appear as a target of has list (P2354) on the item municipality (Q15284) (with a suitable qualifier) or municipality of Spain (Q2074737)
• the inverse is not conventional, since we do not expect there to be an item that is a "list of Spains" -- the value of is a list of (P360) on list of cities of Spain (Q189098) is municipality of Spain (Q2074737), not Spain (Q29). We also do not necessarily expect full inverse matching -- we do not expect on human (Q5) a listing of all lists relating to humans, nor on Spain (Q29) a listing of all lists relating to Spain -- only those that might be considered notable enough to include in its infobox.

These constraints should therefore all probably be dropped, unless a way can be found to suitably qualify them. Jheald (talk) 23:27, 25 November 2015 (UTC)

The initial sample might not be ideal. Q2074737 could be a better sample.

As for the constraints, let's just avoid making them mandatory.

Given the various ways is a list of (P360) is being used, maybe named after (P138) could work better. --- Jura 08:48, 26 November 2015 (UTC)

@Jura1: Maybe. But another thing: why have you made P31 mandatory? I would have thought, if anything, lists would be more likely to be created for classes. (Except for cases, like Spain, where we're using this for lists related to a thing). Jheald (talk) 09:12, 26 November 2015 (UTC)

In theory I guess that's true. In any case, I will remove "mandatory=true". --- Jura 09:19, 26 November 2015 (UTC)

I added both. Somehow I think this property might have been defined too large. Should Q29 include all lists related to Spain? --- Jura 09:29, 26 November 2015 (UTC)

@Jura1: No. The purpose is to allow Q29 to include some lists related to Spain. Jheald (talk) 11:23, 26 November 2015 (UTC)

Using inverse constraint (Q21510855)

Due to contribution the User:Xaris333 request me to explain the statement property constraint (P2302)inverse constraint (Q21510855)property (P2306)is a list of (P360):

by Wikidata property example (P1855) would mean this:

• President of the French Republic (Q191954)has list (P2354)list of presidents of France (Q29580)
• list of presidents of France (Q29580)is a list of (P360)President of the French Republic (Q191954)

and that would mean:

• Emmanuel Macron (Q3052772)instance of (P31)President of the French Republic (Q191954)

conversely, it also makes no sense:

• Emmanuel Macron (Q3052772)instance of (P31)human (Q5)
• President of the French Republic (Q191954)has list (P2354)List of humans
• list of presidents of France (Q29580)is a list of (P360)human (Q5)

it is correct

• Emmanuel Macron (Q3052772)instance of (P31)human (Q5)
• Emmanuel Macron (Q3052772)position held (P39)President of the French Republic (Q191954)
• President of the French Republic (Q191954)has list (P2354)list of presidents of France (Q29580)
• list of presidents of France (Q29580)is a list of (P360)human (Q5)position held (P39)President of the French Republic (Q191954)

Thus, a inverse constraint is not given and therefore should not be inserted. --Labant (talk) 02:09, 1 January 2019 (UTC)

Restrictive constraint?

Right now, values must be "instance of" "wikimedia list article". This excludes subclasses of the latter, so an entry with "instance of = Wikimedia information list (Q80096233)" triggers an exclamation mark. IMO, subclasses should also be included.
