EPCIS Transformation

EPCIS Transformation (Transformation Event)

This page describes the XML to JSON mappings for a transformation (Transformation Event).

Note: ILMD (Instance/Lot Master Data) also generates (layer: 'object', label: 'lotILMD')

GS1 to JSON mapping

This section shows the GS1 XML to JSON mappings. JSON keys are on the left, and the XPaths to the corresponding tag in GS1 XML are on the right, separated by a colon character (:).
