Full title and description

Road vehicles — Open Test sequence eXchange format (OTX) — Part 2: Core data model specification and requirements. This International Standard defines the core OTX data model, its syntactical and semantic rules, and the requirements derived from Part 1 use cases for describing and exchanging test sequences in a machine‑readable and human‑readable form.

Abstract

This document specifies the OTX core requirements and an exhaustive core data model specification. It covers syntactical entities (parameterised procedures, declarations, data types, statements and flow control constructs), semantic rules for interpretation, UML class and activity diagrams, and XML schema definitions (XSD) for the OTX core. The specification supports a specification/realisation concept for hybrid (human‑ and machine‑readable) sequences and includes rules for comments and exception handling; it deliberately excludes domain‑specific statements or data types. The ISO published XML schema (XSD) for the OTX core is made available alongside the standard.

Scope

Specifies the core requirements and data model for the Open Test sequence eXchange format (OTX) used to document and exchange diagnostic and test sequences for road vehicles. The scope covers the description of generic programming-like constructs (parameters, constants, variables, data types, expressions, arithmetic/logic/string operations, control flow, procedure calls, exception handling) and the semantic rules that determine interpretation of OTX documents. It is intended to enable vendor‑ and tool‑independent transfer of test sequence logic between suppliers, manufacturers and service organisations; domain‑specific extensions are handled in separate parts of the OTX family.

Key topics and requirements

• Core OTX data model: exhaustive definition of syntactical entities and their relationships (UML class diagrams).
• Semantics: UML activity diagrams and prose definitions that specify interpretation rules for statements and constructs.
• Language constructs: procedures (parameterised), variable/constant declarations, data types, expressions, assignments, calls, loops, branches and returns.
• Exception handling and error semantics for robust test sequence execution.
• Specification/realisation concept supporting hybrid (human‑readable and machine‑readable) test sequences and floating comments.
• XML schema (XSD) deliverable for the OTX core to enable tool interoperability.

Typical use and users

Used by automotive OEMs, ECU and diagnostic tool suppliers, test engineers, system integrators and service organisations to author, document, exchange and automate diagnostic and test procedures. Typical application areas include ECU diagnostics, calibration, end‑of‑line testing and other in‑plant or workshop test automation where a standardized, tool‑independent test sequence format is required. The OTX core is also used by tool vendors to implement interoperable authoring and execution environments.

Related standards

ISO 13209 is a multipart family: Part 1 defines general information and use cases (ISO 13209-1), Part 2 defines the core data model (this document), and Part 3 covers standard extensions and their requirements (ISO 13209-3). The ASAM OTX specifications and extension work are related initiatives providing complementary tool and extension definitions that align with ISO 13209. Implementers often use the ISO parts together with ASAM OTX resources for broader tooling support.

FAQ

Q: What is this standard?

A: ISO 13209-2:2022 is Part 2 of the OTX (Open Test sequence eXchange) series; it specifies the core data model and requirements for representing and exchanging automotive test sequences in a standardized, tool‑independent format.

Q: What does it cover?

A: It covers the core syntactical constructs and semantic rules for OTX (procedures, variables, data types, expressions, control flow, exception handling), UML diagrams, and an XML schema (XSD) that enables machine‑readable exchange of test sequences. Domain‑specific statements are outside the core and handled in extensions/other parts.

Q: Who typically uses it?

A: Automotive manufacturers (OEMs), ECU suppliers, diagnostic and test tool vendors, test engineers and service organisations use it to author, share and automate diagnostic/test sequences across tools and organisations.

Q: Is it current or superseded?

A: This is Edition 2 published in 2022 and is the current ISO edition of Part 2, replacing the 2012 edition (ISO 13209-2:2012). Confirmed publication record and status are shown in the ISO bibliographic entry.

Q: Is it part of a series?

A: Yes — ISO 13209 is a multipart standard: Part 1 covers general information and use cases (ISO 13209-1), Part 2 is the core data model (this document), and Part 3 addresses standard extensions (ISO 13209-3); implementers commonly use multiple parts together.

Q: What are the key keywords?

A: OTX, Open Test sequence eXchange, XML, XSD, UML, diagnostic test sequences, ECU testing, automotive test automation, data model, exception handling.
