This effort is super to see. As a Wikidata dilettante I was wondering if any thought has gone into what to do when data sources do not agree about a particular measurement. For example, consider the most basic example from the format [3]:
Population was __________ in ____
What if the World Bank says the population was 313.9 milion in 2012 but the US Census says it was 313,999,179 on July 19, 2012? Is there the ability to record the source of the data in Wikidata?
Population was __________ in ____ according to ______
Otherwise couldn’t the bots potentially stomp on each other? Or will some coordination happen where data from a particular source and bot will be privileged over others? How will that be documented? Or perhaps bots can watch for disagreements about a measurement (different value for the same property at the same time) and flag them for downstream processing by people? In a way, seeing how divergent these data sources are is interesting in itself.
I’m not trying to throw a wrench into the gears, I was just curious if there is an established Wikidata way to answer this question when it (inevitably) comes up. Perhaps I’m mistaken, but it seems to me that people disagreeing on Wikipedia is a substantially different situation than bots disagreeing on Wikidata. The bots will trample on each others work without a care, but people have the potential to discuss, negotiate and arrive at a solution. It seems like we might need to build some of this care into the data collection tools proposed for this project?

hi alex,
i saw on https://www.wikidata.org/wiki/Wikidata:Property_proposal/Economics a hint to provide sample data. would it be not an option to provide a couple of data points to make the life of persons easier, instead of making them open links and tables?

Yes Wikidata has a mechanism for adding qualifiers and references to claims.
Where there are multiple values we can also mark one of them as preferred and then simple queries will just get the preferred value.
For population figures each value would typically have qualifiers for * Point in time (when the population figure applies) * Determination method (census, estimate, whatever) * Applies to part (total, black, white, christian, muslim etc.) And each value would have a reference with the organisation, the url, the date the info was published, the date the info was retrieved etc.
The most current total value would be marked as 'preferred'. Values which are widely known but considered unreliable would be included but marked 'deprecated'.
All these properties have already been implemented and we are starting to add them to items.
Hope this helps

This is good news, and helps a lot — thanks for taking the time to respond Joe. It may be a lot of work, but it would be great if you could reference the actual property names by URL for the properties you mentioned.

Sure. Here they are:
- population (P1082) https://www.wikidata.org/wiki/Property:P1082: number of people inhabiting the place - point in time (P585) https://www.wikidata.org/wiki/Property:P585: time and date something took place, existed or a statement was true - determination method (P459) https://www.wikidata.org/wiki/Property:P459: qualifier stating how a value has been determined - applies to part (P518) https://www.wikidata.org/wiki/Property:P518: part of the item for which the claim is valid
Use Property search https://www.wikidata.org/w/index.php?title=Special%3ASearch&profile=advanced&search=&fulltext=Search&ns120=1&redirs=1&profile=advanced to search for properties Help:Sources https://www.wikidata.org/wiki/Help:Sources has info on references and properties to use with them.
