N2 - This report describes general principles for standardizing soil properties/observations that are served from WoSIS (WorldSoilInformation Service) as ‘wosis_latest’. Data for nominally similar soil properties, collated from disparate sources, are grouped according to major features of the corresponding analytical methods; that is, the properties are grouped according to ‘operational definitions’. For example, major features for defining soil pH, for example, are the sample pretreatment, extractant solution (water or salt solution), and in case of salt solutions the salt concentration (molarity), as well as the soil/solution ratio. A further descriptive element may be the type of instrument used for the actual laboratory measurement.
