ISO IEC 24724:2011 pdfダウンロード。Information technology — Automatic identification and data capture techniques — GS1 DataBar bar code symbology specification
1 Scope
This International Standard defines the requirements for the GS1 DataBar symbology family. It specifies the characteristics of the GS1 DataBar symbology family, data character encodation, symbol formats, dimensions,print quality requirements, error detection, and decoding algorithms.
For GS1 Composite symbols, ISO/IEC 24723 defines the two-dimensional component.

3 Terms, definitions, abbreviated terms and mathematical operators
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19762-1, ISO/IEC 19762-2 and the following apply.
NOTE For terms which are defined below and in ISO/IEC 19762, the definitions given below apply.
3.1.1
2D component
two-dimensional portion of a GS1 Composite symbol, which encodes supplemental information about an item,such as its lot number or expiration date
3.1.2
AI element string
character string containing an application identifier followed by its associated data field
3.1.3
encodation methods
compaction schemes used by GS1 DataBar Expanded and 2D components to encode commonly used AI element strings in binary strings that are shorter than would be required using general data compaction for the symbology
3.1.4
indicator digit
leading digit of a GTIN-14 item identification number used to differentiate multiple levels of packaging or to indicate a variable measure item
3.1.5
linear component
linear portion of a GS1 Composite symbol, which encodes the primary identification of an item
3.1.6
linkage flag
indicator encoded in a GS1 DataBar or GS1-128 linear component to signal if a 2D component accompanies the linear component
3.1.7
segment
minimum decodable portion of a bar code symbol, consisting, in GS1 DataBar, of a symbol character and its adjacent finder pattern
3.1.8
GS1-128
subset, specified in GS1 General Specifications, of Code 128 as defined in ISO/IEC 15417
3.1.9
voting
decoding technique whereby decoded segment values are saved along with a count of the number of times they have been decoded
NOTE Voting is used for decoding GS1 DataBar by segments such as when used with omnidirectional scanning.
