Re: [Wikidata-l] When the source says the information provided is dubious
Property proposal started as: https://www.wikidata.org/wiki/Wikidata:Property_proposal/Generic#statement_disputed_by I guess all additional parameters (page, chapter, etc) can go in the references section. We will be able to say things like: birthfollowed bybaptism ---time span until next event 1-7 days ---disputed by GerardM What about the uncertainty qualifier? What would be a good name? statement considered uncertain by?

Re: [Wikidata-l] When the source says the information provided is dubious
We could create a new qualifier like ''contradicted by'' or ''disputed by''. The sourcs are a problem though as we can source only the totality of a claim, not only a qualifier of this claim, so we would have to source all the sources for the claim and it's disputation sources in the source without order.. 2014-05-05 18:26 GMT+02:00 P.

Re: [Wikidata-l] When the source says the information provided is dubious
Hi, These sort of things could also be modeled with another statement and opposite properties. If there is one Statement with the claim Chopin -- creator_of -- Nr. 17 with multiple source (Kobylańska and others), another statement with the claim Chopin -- not_creator_of -- Nr. 17 with a source (Chomińsk) can be added. I dont know if this sort of properties is wanted though.

Re: [Wikidata-l] When the source says the information provided is dubious
One alternative would be XX author *unknow value* with the disputer as a source. To express uncertainty we could also use a statement which says the author is *one of *the french painter in the years 1500 minus Leonardo, and create the appropriate class, although we do not have all the expressive power right now to say that. Basic set operation like set union or set complement in another set or disjoint with could be good for that by the way (unfortunaltely disjoint with has not really been well accepted by community). 2014-05-06 17:18 GMT+02:00 Joe Filceolaire filceola...@gmail.com: Having a property with multiple values can mean a number of things: * All the values are equally valid e.g. because a work has multiple authors * All values are valid but one is preferred - usually the current value e.g. when we have population figures back over time or all the kings of Denmark. * One of the values is shown because it is widely used but is deprecated because it is wrong e.g. Beethoven born on 17 December 1770 (that his date of baptism so he must have been born a few days earlier).

Re: [Wikidata-l] When the source says the information provided is dubious
David, I assume you are referring to books. The same is true for works of art. The reason why these statements are still valuable is because it is an attribution based on grounds determined by someone somewhere and based on that loose statement alone are therefore considered of interest. You basically make a decision to include the statement or not, as you see fit. When it comes to people, one source may say Pete was the son of Klaus, while another source says Pete was the younger brother of Klaus. I think it's just a question of picking one on Wikidata to keep the family aspect of the relationship (whichever it is) intact, and sooner or later one or the other will be chosen. It's a wiki after all.

Hi Jane, No, I was not referring to books in particular, but of course it could be applied to books as well, and to works of art, and to many things in general. I agree that the statement is valuable and that it should be included, but I don't know how to represent it.

Re: [Wikidata-l] When the source says the information provided is dubious
Hmm, I guess I am still not getting it - both of your examples wouldn't make it into one of my Wikipedia articles, and I would probably remove them from an existing article if I was working on it. If it's not factual enough for Wikipedia, then it's not factual enough for Wikidata. I recall a situation where painter A was documented as a pupil of painter B who according to the sources died when painter A was just a young boy of 8. Either very young children could become pupils of other painters, or the original document got painter B mixed up with someone else. Either way it is highly doubtful that painter A was strongly influenced professionally by the art of B.

Re: [Wikidata-l] When the source says the information provided is dubious
Well in the case of attributions of artworks, these things tend to go back and forth a lot, so museums take a fairly pragmatic approach when they invent a pseudo-artist. They will attribute something like a previously attributed B to school of B or follower of B and sort it as B for all other intents and purposes. In the creator field of the artwork template on Commons we have the after qualification, which softens the attribution quite a bit - are you looking for something like that? 2014-05-05 15:43 GMT+02:00, David Cuenca dacu...@gmail.com: Jane, this info is in Wikipedia.
