The document summarizes the evolution of data citation practices over time. It discusses how data citation was initially part of literature but became more complex with digital data. Early efforts in the 1990s-2000s had little traction. Starting in the mid-2000s, multiple disciplines began developing their own data citation approaches and guidelines, with DOIs becoming a major driver. There is now a consensus phase with joint principles being developed, though implementation is just beginning and will require local cultural changes. The document provides examples of how data is currently cited and discusses best practices around identifiers, versions, and microcitations.
