Planned useI'd like to use this property to indicate the number of people donating blood at least once during humanitarian activities of an aid organization. Is important specify the year within which the declaration is valid with a qualifier point in time (P585).
See alsonumber of volunteers (P6125)


At the moment i could add for a person the role of blood donor, but for an organization the number cannot be added; i'm proposing this property because i would like to add the number of blood donors of the national Red Cross and Red Crescent society (Q1968122) avaiable on Federation-wide Databank and Reporting System (FDRS).

  • The example that list the numbers without any regard for the time frame for which the statement is true seem questionable. ChristianKl❫ 21:58, 23 November 2020 (UTC)
  • sorry, i didn't add, but for each data about the number of donors, the period within which the declaration is valid should be specified with a qualifier point in time (P585) (about Italian Red Cross example, is important add 'point in time' to specify '2018' as valid data). Are you agree? LiaFla 11:21 24 November 2020 (UTC)
    • Yes, specifying that we want to store yearly data is important. It makes it clear how the property is intended to be used. Yearly data is likely fine while daily data would be too much statements. ChristianKl❫ 13:32, 24 November 2020 (UTC)
      • thank you, i just added it in "planned use". LiaFla 19:07 24 November 2020 (UTC)
