CSA ISO IEC TR 19764-14 (2019): Harmonized Vocabulary for Data Structures in Automatic Identification and Data Capture
A technical overview of the Canadian adoption of the ISO/IEC Technical Report on data configuration and syntax for AIDC technologies
Scope and Purpose
CSA ISO IEC TR 19764-14 (2019) is the Canadian adoption of the International Technical Report ISO/IEC TR 19764-14, part of the series that establishes a harmonized vocabulary for Automatic Identification and Data Capture (AIDC) techniques. This part specifically addresses data structure terminology, configuration rules, and syntax conventions used across AIDC technologies such as barcodes, RFID, NFC, and optical character recognition.
The purpose of the standard is to eliminate ambiguity in the definition and communication of data formats, encoding rules, and data configuration parameters. It provides a common language for developers, system integrators, and end-users to ensure interoperability and consistent interpretation of data structures in AIDC systems. The standard applies to any application where data is encoded in machine-readable symbols or tags, including logistics, healthcare, retail, manufacturing, and asset tracking.
Note: CSA ISO IEC TR 19764-14 (2019) is identical in content to ISO/IEC TR 19764-14:2019 and is classified as a Technical Report, meaning it serves as informative guidance rather than prescriptive requirements.
Technical Requirements and Terminology
Key Definitions
The standard defines a core set of terms that unify existing vocabularies from various AIDC standards. These include:
- Data Carrier: The physical medium that holds the encoded data (e.g., linear barcode, 2D matrix, RFID tag).
- Data Structure: The logical organization of data elements within a carrier, including delimiters, identifiers, and message headers.
- Data Syntax: Rules governing the sequence, grouping, and representation of data characters.
- Data Configuration: Parameters that define how data is encoded, such as character sets, error correction level, and symbol size.
- Application Identifier (AI): A prefix that defines the meaning and format of the data that follows (commonly used in GS1 standards).
Data Structure Rules
CSA ISO IEC TR 19764-14 (2019) describes a generalized data structure model that accommodates fixed-length and variable-length fields, element delimiters, and nested data groups. The model ensures that data can be parsed consistently across different reading devices and software platforms.
Key technical specifications include:
- Identifier Fields: Unique code that identifies the data type or source (e.g., ISO/IEC 15434 header).
- Data Fields: Contain the payload, which may be alphanumeric, numeric, or binary.
- Separators: Delimiters to indicate field boundaries (e.g.,
<GS>in GS1 syntax). - Terminator: End-of-message marker (e.g.,
<EOT>).
Important: While the standard harmonizes terminology, it does not prescribe which specific data structure syntax to use; rather, it provides a framework for comparing different syntaxes.
Implementation Highlights
Implementing CSA ISO IEC TR 19764-14 (2019) in AIDC systems requires attention to the following areas:
- Multisystem Interoperability: Use the standardized terms and data structure models to map between different AIDC data formats.
- Encoding Configuration: Document data configuration parameters using the standard’s terminology to avoid misinterpretation.
- Software Parsing: Develop parsers that recognize the generic data structure model and can adapt to specific syntaxes.
- Training and Documentation: Align internal vocabulary with the standard to reduce communication errors across teams and vendors.
The following table summarizes the primary data structure elements defined in the standard and their general use:
| Element | Description | Example Syntax (ISO/IEC 15434) | Note |
|---|---|---|---|
| Header | Identifies the syntax and data format. | [)>06 | May vary between standards |
| Application Identifier | Designates the meaning of a data field. | 01 (GTIN) | From GS1 General Specifications |
| Data Separator | Delimits fields within a message. | <GS> (0x1D) | Format-sensitive delimiter |
| Segment Terminator | Indicates end of a logical message. | <EOT> (0x04) | Optional in some syntaxes |
| Data Content | Payload with actual information. | 012345678905 | Variable length |
Implementation Tip: When designing a new AIDC system, refer to the standardized vocabulary defined in CSA ISO IEC TR 19764-14 (2019) early in the requirements phase. This will reduce integration issues and simplify certification processes.
Compliance and Application Notes
As a Technical Report, CSA ISO IEC TR 19764-14 (2019) does not impose compliance requirements like a normative standard. However, its adoption can streamline certification to other AIDC standards (e.g., GS1, ISO/IEC 15434, ISO/IEC 18000 parts). Compliance in practice involves:
- Using the defined terms in system documentation and contracts.
- Ensuring that a system’s data structure documentation aligns with the generic model presented in the report.
- Including the standard’s definitions in training materials to promote cross-vendor understanding.
Caution: Because this is a Technical Report rather than a normative standard, it should not be cited as a sole requirement in contracts. Always pair it with the corresponding normative AIDC standards that define actual encoding and symbol requirements.
Intended Audience
This standard is intended for standards developers, system architects, software developers, and quality assurance professionals involved in the specification, design, or testing of AIDC data structures.
Frequently Asked Questions
Q: Is CSA ISO IEC TR 19764-14 (2019) identical to the ISO/IEC version?
A: Yes. The Canadian Standards Association (CSA) adopts ISO/IEC TR 19764-14:2019 without modification. The only difference is the document number and status as a Canadian national standard adoption. Technical content remains unchanged.
A: Yes. The Canadian Standards Association (CSA) adopts ISO/IEC TR 19764-14:2019 without modification. The only difference is the document number and status as a Canadian national standard adoption. Technical content remains unchanged.
Q: Do I need this standard if I already implement GS1 or ISO/IEC 15434?
A: This standard does not replace existing syntax standards. Instead, it provides a harmonized vocabulary and data structure model that can be used to compare, document, and teach different syntaxes. It’s supplementary to other application standards.

Q: How does this standard affect my RFID system?
A: RFID systems rely on data structures defined in standards like ISO/IEC 18000 and ISO/IEC 15961. The vocabulary in Part 14 can be used to describe those data structures in a consistent manner, but it does not override the RFID-specific coding rules.

Q: What is the difference between a Technical Report and a full International Standard?
A: A Technical Report (TR) is informative and provides guidance, best practices, or supplementary content. A full International Standard contains normative requirements that must be followed for compliance. TRs are often precursors to later normative standards or serve to harmonize existing practices.
