Anti trust caution

Anti-Trust Caution

GS1 and the GSMP operate under the GS1 anti-trust caution. Strict compliance with anti-trust laws is and always has been the policy of GS1.

The best way to avoid problems is to remember that the purpose of the committee is to enhance the ability of all industry members to compete more efficiently.

This means:

  • There shall be no discussion of prices, allocation of customers, or products, etc.

  • If any participant believes the group is drifting towards an impermissible discussion, the topic shall be tabled until the opinion of counsel can be obtained.

  • The full anti-trust caution is available in the Community Room if you would like to read it in its entirety.


Meeting etiquette

Meeting Etiquette

Meetings will begin promptly at designated start times

Avoid distracting behaviour:

  • Place all mobile devices on silent mode

  • Avoid cell phones

  • Avoid sidebar conversations

    Speak in turn and be respectful of others

    Be collaborative in support of the meeting objectives

Guideline scope1

Guideline Scope

Three Best Practices:

  • Design business-level applications, databases, and messages to be independent of the data capture method and the data carriers used.

  • Confine the use of data carrier-specific representations to the lowest levels of implementation architecture.

  • Adopt best practices for implementing translations between data carrier-specific representations and application-level representations.


Data carrier independence

Data Carrier-specific encoding of business data


Application level syntax

Application-Level Syntax

  • Key concept: Use application-level syntax at the business application level (not carrier-specific syntax)

Right:

<gtin>80614141123458</gtin> <serial>6789<serial>

Wrong:]C10180614141123458216789

Application level syntax characteristics

Application-Level Syntax Characteristics

  • Accommodates every possible value of a GS1 Identification Key without limitation, and so it is capable of representing a key read from any data carrier.

  • Does not include additional information that is specific to a particular type of data carrier.

  • Provides only one possible way to represent each distinct key value within the syntax.

    • Therefore, an application can determine whether two values refer to the same real-world entity by a simple string comparison, with no additional normalization or parsing required


Application level syntax1

Application-Level Syntax


Carrier specific syntax

Carrier-Specific Syntax


Interoperability principles

Interoperability Principles

  • Design business applications, messages, and databases to accept data from any data carrier

    • accept the full range of data values defined by GS1 Standards; do not carry data carrier-specific restrictions to this level

  • Business applications, messages, and databases should only use application-level syntax:

    • “Plain” key

    • GS1 Element String

    • EPC URI


Serial number issues

Serial Number Issues

  • Leading zeros can lead to errors:

    • 7, 07, and 007 are all different serial numbers according to GS1 Gen Specs

    • But some applications don’t respect this

      • MS Excel is a well-known example; it treats a GS1 serial number as an ordinary number

    •  Avoid the problem by not assigning leading zeros

  • Variable-length serial number leads to variation in bar code size

    • QA and packaging design often rely on fixed size symbols

    •  Avoid the problem by assigning a fixed-length serial

  • 96-bit RFID tags are limited in serial number capacity

    •  Avoid the problem by staying within allowed range

  • Putting it together, the most interoperable serial number allocation policy is:

    • 10000000000 – 99999999999; or

    • 100000000000 – 274877906943

  • But applications should accept any valid serial number and never add or remove leading zeros
