Implementation Guides

*NOTE: The messaging indicated in the Trusted Source of Data (TSD) standards and guidelines has been built upon a framework where the Federated Object Naming Services (F-ONS) serves the purpose of an index. This “index” shows which aggregator has information on what Global Trade Item Number (GTIN)/product. For GS1 Source Certification, an aggregator must prove that they have implemented the standard and have the capability to query the index, however use of the index and bilateral connections with other aggregators is optional.
