GDSN
Global Data Synchronization Network (GDSN) is GS1’s standard for synchronizing basic information such as items, locations, and prices. On GS1’s global website you can learn more about GDSN and find a schedule for this year’s GDSN releases.
Trade Item Information
GS1 Trade Item information is a solution for electronically exchanging information about items, for example measurements, weight, item numbers, and sustainability. If you are a supplier and need to send article information, you will learn the basics in the Guideline for trade item information. The guide also provides information to system builders and recipients of article information. If you are a developer and need to build or maintain a system used to submit item information, then you will find the technical documentation that you need under Current specifications and Upcoming specifications below.
GS1 measurement rules
When measuring an item’s dimensions, such as height, width, and depth, it is important that everyone measures in the same way so that there are no misunderstandings. When the dimensions in the item information match the actual item’s dimensions, the store can make an accurate shelf planning. In addition, it is possible to plan a transport so that everything fits and the truck’s capacity is optimally utilized.
Measure the outer dimensions of the item
Remember to always measure the outer dimensions of the item since it is the outer dimensions that are needed for shelf planning and in transport. Using the inner dimensions that you receive from your packaging vendor may result in your customer’s shelf planning not working or the item not being placed in the bin.
Measurement rules for consumer and non-consumer items
Measurement rules for all packaging types can be found in the global standard GDSN Package Measurement Rules. The parts describing measurement rules for packed consumer and non-consumer items are translated into Swedish in GDSNs mätregler för förpackningar. Please note that consumer and non-consumer items should be measured in different ways.
Product images
GS1 Product Image Specification Standard is a GS1 standard for product images. It contains technical rules and guidelines for storing digital images linked to products identified by GS1 article numbers. The document also contains some recommendations regarding image quality, but does not describe how images should be delivered or published between different parties.
The standard contains guidelines for product images intended for online and print marketing, as well as planogram images used in store shelf planning.
GS1 Electronic Data Interchange (EDI)
GS1’s two standards for electronic commerce are GS1 EANCOM and GS1 XML. GS1 UN/CEFACT specifies how GS1 standards are to be used in UN/CEFACT XML messages.
ESAP – Business processes for electronic commerce
ESAP is business processes for electronic commerce and is used to facilitate for companies that have chosen to communicate via GS1 EDI (Electronic Data Interchange). The ESAP documentation is primarily aimed at operational managers of suppliers and system developers.
The processes follow GS1 standards and are documented in implementation guides and specifications designed to help different industries get their information flows organized.
Data Communications
To send business information over any type of network, such as the Internet, a file transfer protocol is required. GS1 recommends EDIINT AS2 (EDI over INTernet Applicability Statement 2). EDIINT AS2 securely transmits data over the Internet using HTTP as the transport protocol. Some of the benefits of AS2 are:
- Digital signatures make it possible to verify the sender and prevent the information from being manipulated on the way between the sender and the receiver.
- Encryption ensures that the information cannot be read by unauthorized persons during transmission.
- The use of ack/neck signals means that the transmitter and receiver always agree that a message has been sent and/or received.
Warehouse Management
Here you can find the guideline and technical specifications for Warehouse Management. The specifications are developed by an international working group based on GS1 XML.
Transport Management
Here are the guidelines and technical specifications for Transport Management. Most of the specifications have been developed by an international working group, while the Transport Invoice has been developed by a national working group.
EPCIS
Electronic Product Code Information Services (EPCIS) is GS1’s standard for sharing event information, which allow you to track a ship-to-customer delivery, track a customer-to-manufacturer delivery, and find out if a product is genuine or counterfeit.
Basic documentation
Here you can find basic technical documentation for GS1’s standards for identification, data capture and information sharing.
Identification, barcode and RFID labelling
The GS1 General Specifications is the basic rule book that describes the GS1 system and how to use it.
GS1 Architecture
GS1’s system architecture defines and describes the architecture of the GS1 system, shows how the different parts relate to each other and outlines the technical principles that form the basis of the system’s design.
