Ensuring the technical integrity of the GS1 system, as well as the consistent and efficient inter-operation of all the various GS1 standards, is of great importance and the GS1 Architecture publications are one of the main tools to help achieve this. A brief overview can be found in the GS1 system architecture flyer.
The GS1 Architecture Principles (Release 3, May 2016)
Sets out the architectural principles that underpin the GS1 system.
The GS1 System Architecture (Release 5, April 2016)
Defines and describes the GS1 system architecture, shows how each part of the system is related and outlines the underlying technical foundations that have guided their design.
The GS1 System Landscape (Release 5, April 2016)
Provides a comprehensive inventory of the GS1 standards and catalogues and classifies them into topic areas.
The GS1 EPC/RFID Architecture Framework standards (Issue 1.7, May 2015)
Defines and describes the EPCglobal Architecture Framework - this document is no longer maintained as the GS1 System Architecture covers most topics.
GS1 Networked Services Architecture (Issue 1, July 2013)
Addresses the concept of GS1 Networked Services and provides a series of recommendations.
Intro to the GS1 Architecture – Gain an understanding of the GS1 Architecture and the GS1 Architectural Principles by watching this short recorded presentation.
The GS1 Architecture Group is available to respond to architectural “requests for finding (RFF)” submitted by members of the GSMP community.
GTIN Reuse – Jan 2017
This Finding addresses the question of GTIN reuse and includes the conclusion 'The architectural position is that GTINs should not be reused'.
Typing within the GS1 System – Mar 2015
This Finding addresses the question 'how can a subset of relevant objects with specific same characteristics be detected in real-time in case of automated mass detection of a large number of similar objects which are identified with the same GS1 Key?'
Using external identifiers in the GS1 System – Nov 2014
The GS1 Transport & Logistics community submitted the Request For Findings on "how to integrate external identifiers for transport equipment (such as BIC codes (containers) and EVNs (rail vehicles)) in the GS1 System?". This Finding provides guidance and recommendations for GSMP groups to address such requests to recognise external identifiers in the GS1 System.
Attributes associated with multiple GS1 ID Keys – April 2014
The question raised was can a system that has been programmed to associate attribute data with a particular key, also identify the same attribute data with a different GS1 key and if so what is the impact on existing systems? This Finding scopes the issue and provides the framework for GSMP groups to address such questions.
GS1 Company Prefix usage and definition in all GS1 Standards -Sept 2015 (Release 1.2)
The GS1 Company Prefix is a fundamental building block of the GS1 System. There is, however, no formal specification (character set, minimum and maximum lengths, construction, restrictions, etc.). This Finding catalogues the usage in various GS1 System components and provides clear recommendations for improvement and clarity.
Use of the term Brand Owner in GS1 ID Key assignment - Dec 2012
For historic reasons the term ‘brand owner’ has been defined as the ‘The party that is responsible for allocating GS1 System Identification Keys’. With the introduction of new GS1 ID Keys, the term ‘brand owner’ is sometimes misleading and this Finding scopes the issue and makes recommendations to improve.
GTIN allocation when not assigned at source - Dec 2012
Sometimes products are not assigned a GTIN by the brand owner at source and an issue arises where two, or more, importers of these products wish to assign a GTIN prior to commercialisation. This Finding outlines the potential solutions available.
Compatibility of GS1 EANCOM and GS1 XML for non-transactional messages – Aug 2011
The compatibility of the two supported message standards, GS1 EANCOM and GS1 XML, particularly with regard to master data synchronization was questioned. This Finding outlines the recommendations on the use of each in particular with respect to the synchronisation of master data through GDSN and connected data pools.
Use of GRAI in eCom Trade Messages - June 2011
During the development of guidelines for Management of Reusable Transport Items (RTIs) with eCom messages, questions were raised on the use of the Global Returnable Asset Identifier (GRAI) when ordering Reusable Transport Items. This Finding clarifies that the GTIN is the only GS1 Identification Key recommended.
GS1 ICOM (Intergrated Communication) - Jan 2011
A description of how types of business data and modes of communication are integrated in the GS1 system.
Who are members of the GS1 Architecture?
The GS1 Architecture Group members include representatives from End Users, Solution Providers, GS1 Member Organisations and Global Office. The roles and responsibilities of the GS1 Architecture Group are defined in the GSMP Process Manual. This group reports to the Board Committee for Standards (BCS) within the GSMP framework.
