OK, I did not think it might confuse users, the label needs to be changed. It's of course not intended to use in statements which have no value, it's just an attempt to express wikibase data model in Wikidata. https://www.wikidata.org/wiki/Q16354757 is not Wikibase Data model :) I changed the

Hoi, For me it is obvious ... this search for perfection is an enemy of what is good in Wikidata. It destroys the results of queries. It is not usable and it is only of use in a very small percentage of cases. Compare it with the female mayor question. Our issue is that we have not enough data in

You should ask the people that are at this time developping it, and Lydia, how they will handle this. Because they will, it's in the Wikibase DataModel, the same as qualifiers. We will probably be provided with options on how we want to handle ranks, unknown values and so on when we will build a

In wikidata, the absence of a claim about something cannot mean the claim has no couterpart in reality, as Wikidata is an will always be incomplete. For example if we have a series, maybe finished, maybe unfinished, we wil have claims that says: Episode 2 follows Episode 1 Episode 3 follows

Hoi, A question about the example... does that second source really care about this and what do we do when we know this to be incorrect. It is bad enough to want to know about the sum of all knowledge, I do not care for present and past mistakes. Thanks, GerardM On 23 April 2015 at 12:15,

Hoi, That does not clarify it. So what would we say ... it is in dispute sure but the way we work is that we have a child as a known person. So sources may dispute to their hearts content.. It is a relation that goes both ways.. How do we say novalue because it has to be a person ... John Doe does
