Wikidata:Property proposal/operating cost - Wikidata

Return to Wikidata:Property proposal/Generic

capital cost (P2130) already captures the initial capital cost of an object (building, vehicle, etc) but there is no equivalent property for capturing the recurring ongoing costs of maintaining and operating an object.

Qualifiers such as determination method or standard (P459) and valid in period (P1264) would be very important to use with this property as there are many ways to calculate an operating cost for equipment or a building. In the Tesla Model 3 example provided (USD$623/year) this was only an estimate valid at a point in time, for the first five years of ownership of a car, and excluding a number of other operating costs such as electricity and insurance.

  •  Weak support A week support from me, because I think it needs a qualifier of sort. I think the cost of annual ownership can benefit from qualifier of a country, region, city, where it's owned. For example, cost of ownership of Tesla car in Norway and US differ tremendously. Also, I think it would benefit from more time periods like 5 year and so on, but I'm not certain about it. --David Osipov (talk) 12:11, 26 October 2024 (UTC)[reply]
  •  Comment The time span should be specified using duration (P2047) qualifier; otherwise you need to create items for every combination of currencies with day/week/month/year, which would be a nightmare for editors and data consumers. Dexxor (talk) 17:57, 27 October 2024 (UTC)[reply]
  •  Oppose Operating cost will change over time and from place to place, while the cost of building a building is final at a point in time. There is no such thing as a fixed operating cost for most things, typically it will depend on a lot of factors. This means the value will have to be constantly updated and it may also like other time-series data start to accumulate. While the data might be of use to some, in all likelihood it will suffer from being permanently out of date meaning there are better sources for this data. All in all I don't think this is a good fit for a database such as Wikidata. Infrastruktur (talk) 23:06, 8 February 2025 (UTC)[reply]
