What is Global Data Dictionary

The GS1 Global Data Dictionary (GDD) is a repository of the data elements defined across all GS1 Standards.

What is the scope of the Global Data Dictionary?

GS1 Business Message Standards (BMS) and their components with definitions for GDSN 3.1 to latest version, GS1 XML for EDI, and EPCIS 1.0.1. Higher versions will be added upon ratification.

  • Business Messages
  • Business Information Entities - message components and relationship between them
  • Business Data Types
  • Code Lists used in Business Messages

The Business Messages are composed of Business Information Entities that comprise classes of information and their attributes. The attributes, in turn, have data types that may contain code lists.

Structure of Global Data Dictionary

The structure and allowed content of Business Message are published as XML schemas that are used to validate the actual messages exchanged between business partners.
 

 

All the message components have their definitions, relationship to other components and multiplicity - the specified number of times they can appear in the given location of the message. All this information is also published in the GDD. 

GDD contains also code lists used in GS1 EANCOM®.

The specification of GS1 Business Messages and XML schemas defining their structure can be freely downloaded from GS1 website.
