What is the Global Data Synchronization Network (GDSN)?
The Global Data Synchronization Network (GDSN) is a network of interoperable data pools and a Global Registry, the GS1 Global Registry, that allows the timely and “auditable” distribution of certified standardized master data (Trade Item and Party) from a data source to a final data recipient of this information. One of the key advantages of the GDSN is that trading partners have a single point of entry to the GDSN through the certified data pool of their choice therefore avoiding having to pay subscriptions to several data pools. Trading partners do not have direct access to the GS1 Global Registry, unless they act as their own data pool. Within the GDSN, catalogue items are identified by a combination of GTIN, GLN of the data source, and target market (a geographic area where the product is intended to be sold) while parties are identified using a GLN.
