The GTIN Data Collection Tool is a resource to aid countries in automating the physical collection trade item identifiers – namely the Global Trade Item Numbers (GTIN) – encoded in GS1 standardized data carriers (specifically, GS1 2D DataMatrix, GS1-128 linear, or EAN/UPC) that are labelled on physical products. The data collection exercise may be implemented as a part of an effort to establish a robust product master data file that includes both trade item level identification, packaging level hierarchies, and parent-child relationships between unique trade items and generic product concepts. For the proposed data structure, trade item hierarchies are uniquely identified by a GTIN and are packaging level specific (each, inner pack, case, pallet).
