ISO/IEC 24723:2010 pdf – Information technology — Automatic identification and data capture techniques — GS1 Composite bar code symbology specification.
1 Scope This International Standard defines the requirements for the GS1 Composite symbology. It specifies the GS1 Composite symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, and reference decoding algorithms. For those linear and 2D components of GS1 Composite symbols with published symbology specifications, those published specifications apply, except as specifically noted in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

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. 3.1.1 2D component CC 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 CC-A 2D component that is a structural variant of MicroPDF417 NOTE 1 CC-A components can be autodiscriminated from MicroPDF417 symbols, because CC-A components have a unique Rotation of 32 between any two adjacent Row Address Patterns. NOTE 2 CC-A is one of the three choices for the 2D component in a symbol encoded in the GS1 Composite symbology. 3.1.4 CC-B 2D component that is a MicroPDF417 symbol which begins with PDF417 codeword 920, indicating conformance with this International Standard NOTE CC-B is one of the three choices for the 2D component in a symbol encoded in the GS1 Composite symbology. 3.1.5 CC-C 2D component that is a PDF417 symbol which begins with PDF417 codeword 920, indicating conformance with this International Standard NOTE CC-C is one of the three choices for the 2D component in a symbol encoded in the GS1 Composite symbology. 3.1.6 linear component linear portion of a GS1 Composite symbol, which encodes the primary identification of an item 3.1.7 linkage flag indicator encoded in a GS1 DataBar or GS1-128 component to signal if a 2D component accompanies the linear component 3.1.8 RAP Rotation difference between the number designating a Center or Right Row Address Pattern and the number designating the nearest Row Address Pattern to the left, in the same row of a MicroPDF417 symbol, or a CC-A or CC-B component
3.1.9 Row Address Pattern RAP one of a set of patterns made up of three bars and three spaces occupying ten modules, that serve both as start or stop patterns and as row indicators in a MicroPDF417 symbol, or a CC-A or CC-B component 3.1.10 separator pattern pattern between the linear and 2D components of a GS1 Composite symbol 3.1.11 symbol separator character non-data character that is used to break the transmitted data string into separate transmissions, each beginning with the appropriate symbology identifier prefix 3.2 Abbreviated terms AI Application Identifier 3.3 Mathematical operators and notational conventions For the purposes of this document, the following mathematical operators apply. div integer division operator which discards the remainder mod integer remainder after integer division The following ISO notational conventions are used. 0,2 a comma between digits separates the integer from the decimal fraction (e.g. 0,2 equals 2/10) except when used as an (n,k) designation 12 345 a space between digits indicates factors of a thousand
