Re: [Wikidata-l] Wikidata project focused on economic data

Sure. Here they are:

   - population (P1082) : number
   of people inhabiting the place
   - point in time (P585) : time
   and date something took place, existed or a statement was true
   - determination method (P459)
   : qualifier stating how a
   value has been determined
   - applies to part (P518) : part
   of the item for which the claim is valid

Use Property search

 to search for properties
Help:Sources  has info on
references and properties to use with them.

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.

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

Joe

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?

Re: [Wikidata-l] Wikidata project focused on economic data

[Edward Summers]

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?
