The GS1 Global Data Dictionary (GDD) contains thousands of attributes, including both basic and category-specific information, such as allergens for grocery, dosage for health care, and textile material for apparel. The GDD also features multimedia attributes, such as 360-degree and montage images.
While not fully comprehensive, these attributes are sufficient for many use cases, including supply chain, shelf planning, and basic ecommerce listings.
All GDD attributes, however, are not supported by every GS1-certified GDSN data pool. Although these data pools are required to maintain complete support, many function without.
