Understanding GDSN 

GDSN Overview

The Global Data Synchronization Network (GDSN) is a network of interconnected data pools (1WorldSync is one certified data pool) that trading partners use to efficiently and securely share product information. It was developed by GS1 (Global Standards), the entity that creates and updates these standards.

You can leverage GDSN attributes to share logistical, shipping, and regulatory information securely with retailers. You can sync item information into the data pool with as many valid attributes defined as you want, and the retailer can then sync with those items capturing any subset of an item’s associated attributes.

1World Sync (1WS) is a GS1 certified GDSN data-pool, and Salsify is a certified Solution Provider with 1World Sync. Customers submitting information to GDSN with Salsify do so through 1WS.

Data Flow & Hierarchy


GDSN maintains levels of hierarchies, and each level contains separate attributes.  For example, a widget is sold to the consumer with one widget in a package.  There is information for that lowest level of hierarchy: a Global Trade Identification Number (GTIN) that identifies that unit, along with other logistical information like packaging, dimensions, and weight and the details the retailer needs to sell that product. 

But that widget is sold to the store in cases with multiple units in the case, and sometimes multiple inner packs inside the case.  So there are separate product values to identify the case and inner cases separately - a GTIN for the case, its weight and dimensions, and a separate set of information for the inner case.  The cases may be sold to the retailer by pallet, and there is another set of information that describes the pallet.

Data Flow

The flow of data starts with your internal data. It’s imported to Salsify, where it is stored and transformed to meet the GS1 requirements to send to GDSN. With help from our Customer Success team, you’ll prepare your products to deliver the attributes your retailers require, and transform any data necessary to meet validation requirements.

We will help you set up the retailers you’ll publish data to. When your products are ready, you’ll publish your validated product details through Salsify to 1WS, where they’ll be sent to your data pool, and on to retailers through the global registry. The illustration below shows the process of data from your internal systems to a single retailer. Additional retailers will access your product information from your data pool through the same process.

Preparing to Deliver Data to GDSN through Salsify

There are a few steps to get started with GDSN in Salsify. This is a brief overview–you will work with your customer success team who will help you get everything up and running.

Existing Product Content Architecture

The details for each level of hierarchy are stored in Salsify and passed through to GDSN via 1WS. The Customer Success team will work with you to architect the process to pull your existing data from your ERP to work with GDSN.

Attribute Identification

We will help you define a list of attributes that you and your trading partners need, based on some industry-specific and retailer specific readiness reports and your specific retailers’ needs.

Workflow & Readiness Process

We will work with you to set up processes in Salsify to build any additional attributes that you need to pass through to trading partners that aren’t currently available.

We’ll work with you to map the readiness report with attributes you want to pass through to GDSN and the workflows and readiness report will help you identify and fill gaps in your content.

Trading Partner Identification

You will provide a list of the trading partners and their corresponding GLNs and we'll use these in our connector as the destinations for each publish.

Solution Provider Setup

In order for Salsify to sync items on the Customer’s behalf, you will need to have the Salsify GLN set as the Solution Provider of their GLN(s). You will work with your 1WS Rep to have this set up.

Readiness, Testing & Delivery

We will work with you to map your Salsify properties to the readiness reports, we create and test the connection and get you ready to deliver your information to retailers through GDSN.
