Road vehicles - Open Test sequence eXchange format (OTX) - Part 3: Standard extensions and requirements
This document defines the Open Test sequence eXchange (OTX) extension requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. They are listed in Clause 4. The data model specification aims at an exhaustive definition of all features of the OTX extensions which have been implemented to satisfy the requirements. This document establishes rules for the syntactical entities of each extension. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents containing extension features are to be interpreted. The syntax rules are provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions.

Overview
ISO 13209-3:2022 - "Road vehicles - Open Test sequence eXchange format (OTX) - Part 3: Standard extensions and requirements" specifies the extension requirements and data model for the OTX standard. Building on use cases in ISO 13209-1, this part lists formal requirements (Clause 4) and provides an exhaustive definition of OTX extension features. Syntax is defined by UML class diagrams and XML schemas, while semantics are provided by UML activity diagrams and prose definitions. The document establishes rules for syntactical entities and how OTX documents containing extension features must be interpreted.
Key topics and technical requirements
- Extension requirements: Requirements and recommendations derived from Part 1 use cases; entries and priorities are documented (Clause 4).
- Data model specification: Exhaustive definition of extension features to ensure consistent implementation and interoperability.
- Syntax and semantics:
- Syntax: UML class diagrams and XML schemas govern structural rules for extensions.
- Semantics: UML activity diagrams plus prose define expected behavior and interpretation of extensions.
- Modular extensions covered (examples in the standard):
- OTX DateTime extension - standardized date/time handling for test sequences.
- OTX DiagCom extension - diagnostic communication channels, services, patterns, data types, exceptions, variable access and actions.
- OTX DiagDataBrowsing extension - browsing and accessing diagnostic data models.
- OTX EventHandling extension - event definitions, event sources, properties and actions.
- OTX Flash extension - flashing/programming related data types and processes.
- Terminology and normative references: Defined terms, abbreviations, and normative cross-references to ensure shared meaning across implementations.
Practical applications and users
ISO 13209-3 is intended for organizations and professionals involved in automotive test automation and diagnostics who need a standardized, machine-readable test-sequence exchange format:
- Vehicle OEMs and Tier-1/2 suppliers implementing automated test platforms
- Tool vendors building OTX-compliant authoring, execution and diagnostic tools
- Test engineers and integration teams who create, share and execute test sequences for ECUs, systems and vehicle-level tests
- Standards engineers aligning test workflows, diagnostics and flashing procedures with formal specifications
Practical benefits include improved interoperability of test sequences, consistent diagnostic behavior across tools, and reliable exchange of extensions like diagnostic communication, data browsing, event handling and flashing.
