The lack of integration of data into a scientifically credible, globally assembled, information platform with consistent terminology and definitions hinders our understanding of the 4.2 ka BP Event. Using such an information platform, we show the presence of a strong and coherent signal for the 4.2 ka BP Event in northeastern China. Our prototype database approach, guided by semantic analysis and georeferencing, can serve as a guide to the assembly of a larger-scale global 4.2 ka database.
