Furthermore,attention is drawn to the possibility that an implementation of one or more features of this Specification may be thesubject of a patent or other intellectual property right that does not involve a Necessary Claim. Any such patent or otherintellectual property right is not subject to the licencing obligations of GS1. Moreover, the agreement to grant licencesprovided under the GS1 IP Policy does not include IP rights and any claims of third parties who were not participants inthe Work Group.Accordingly, GS1 recommends that any organisation developing an implementation designed to be in conformance withthis Specification should determine whether there are any patents that may encompass a specific implementation that theorganisation is developing in compliance with the Specification and whether a licence under a patent or other intellectualproperty right is needed. Such a determination of a need for licencing should be made in view of the details of the specificsystem designed by the organisation in consultation with their own patent counsel.THIS DOCUMENT IS PROVIDED “AS IS” WITH NO WARRANTIES WHATSOEVER, INCLUDING ANY WARRANTY OFMERCHANTABILITY, NONINFRINGEMENT, FITNESS FOR PARTICULAR PURPOSE, OR ANY WARRANTY OTHER WISEARISING OUT OF THIS SPECIFICATION.

GS1 Digital Link Standard: URI Syntax1IntroductionThis section and its subsections are informativeGS1 defines a wide range of identifiers that underpin the supply chain and retail industry across theworld. This document assumes the reader is familiar with these and the concept of GS1 ApplicationIdentifiers. If not, please see information on [GS1 Identification Keys] and the [GENSPECS] for furtherbackground.This work has been motivated by a number of trends. For example: the desire among retailers tomove to 2D barcodes that can carry more information than just the GTIN; the problems of multiplebarcodes causing scanning errors through conflicts which suggests a need for a single butmultipurpose barcode; the growing expectation among consumers that more information isavailable online about the products they’re considering buying; the brand owner concept of thepack as a media channel linking to multimedia experiences, and more.As a result of this standard, it is possible to represent GS1 identification keys consistently withinWeb addresses as well as within barcodes containing Web addresses, such that a singleidentification approach can support both product identification for supply chain applications and alink to online material for consumer and business partner interactions. It’s this dual functionalityand enormous flexibility that is currently not possible when, for example, Brand Owners embed anunstructured Web page address in a QR Code 1.The scope of the work accommodates all Class 1 and Class 2 GS1 Keys and Key qualifiers (e.g.,serial number, batch number, consumer product variant) and other relevant attributes as the sametechnologies are equally applicable to SSCCs, GLNs, GIAIs, GRAIs, GSRNs etc. While the syntaxcan support Class 2 Keys, it is up to the Class 2 Issuing Agencies to determine whether it’s fit fortheir use. For Class 3 GS1 Keys, GS1 welcomes bilateral discussions with Issuing Agencies to seewhere alignment is possible.This GS1 standard references a number of third-party standards from the Internet EngineeringTask Force (IETF) and the World Wide Web Consortium (W3C).1.1How the GS1 Digital Link standard documents fit togetherRather than one very long document containing every detail, as of version 1.2, the GS1 Digital Linkstandard comprises 4 discrete documents:URI syntax (this document)This document provides some of the background to the design of GS1 Digital Link, highlightingexisting techniques and practices that underpin the World Wide Web, and applying those to theGS1 system. The normative portions set out the detailed syntax of Web addresses (HTTP URIs)that encode GS1 identifiers with exactly the same precision and expressivity as the AI-basedelement syntax used across the GS1 system, notably in the GS1 General Specifications. The GS1Digital Link URI syntax distinguishes between primary keys, such as GTIN and GLN, key qualifiers,such as batch/lot and GLN extension, and attributes such as expiry date and ship-to address. TheGS1 Digital Link URI syntax is the foundation on which all other aspects of the standard are built.CompressionA GS1 Digital Link URI that contains a set of identifiers and attributes may exceed the capacity ofsome data carriers. This document defines a compression/decompression algorithm that minimisesthe length of those Web URIs while retaining two critical features: 1) that the compressed form isstill a URL on the same domain as the uncompressed form, that is, there is no change in ownershipof the URL; 2) that it can be decompressed and the GS1 keys extracted without an online lookup.ResolutionA GS1 Digital Link URI is a particular form of URL and can be used in exactly the same way as anyother URL (this is an important design feature). However, it can also be the gateway to multiplesources of information, both human and machine-readable. This document defines how the keys in1Unless otherwise spec
