5. 1. OTX – former motivation
Electronics Tools & Equipment OTX: Open Test sequence eXchange
1. OTX – former motivation
OTX is an exchange format for diagnostic sequences which are widely used within the automotive industry for diagnostics, testing and reprogramming of electronic components and systems in vehicles.
(Schluesener, Preuschoff, Frisch 2009:92)
Strategic focus on diagnostic domain
OTX-Properties
Core data model
+ Extensions
(e.g. Diagnose-Communication, HMI-Control)
Extension Mechanism enables further extensions
Unified, formal, machine readable markup-language
Abstract description guarantees reusability
Initiator: Daimler, Bosch, VW
Motivation:
Different platforms/systems in
different states of automotive lifecycle
No exchange possibilities for so called
“Prüfabläufe” (diagnostic-sequences)
HiL testing of diagnostic sequences

6. 2. OTX – status 20.12.2008 New Work Item Proposal / ISO (Number 13209)
Electronics Tools & Equipment OTX: Open Test sequence eXchange
2. OTX – status
New Work Item Proposal / ISO (Number 13209)
Task Force 14 within ISO/TC22/SC3/WG1-Data Communication
Will be submitted as a draft international standard by the End of February 2012
Current version of the schema is 0.9.5
ISO 13209
(URL:
Part 1: Use Cases
This is part of the preamble and has essentially remained unchanged for the past 18 months
Part 2: Core Data Model
This has already been submitted for draft international standard
Part 3: Standard Interfaces
This is the last remaining part, and is expected to be submitted by end of February.

7. 3. OTX – future expectations
Electronics Tools & Equipment OTX: Open Test sequence eXchange
3. OTX – future expectations
OTX (Open Test eXchange) format is an emerging ISO standard (ISO 13209) for exchanging vehicle test sequence information that promises to streamline the test authoring process and promote reuse across organizations within your company and between OEMs, suppliers and 3rd party maintenance providers.
(URL: (2011))
Broadening strategic focus: not only diagnostic domain!

11. 7. OTX – markup characteristics
Electronics Tools & Equipment OTX: Open Test sequence eXchange
7. OTX – markup characteristics
XML based language
Platform independent
Great number of off-the-shelf solutions
World-wide accepted
No own grammar needed
Syntax of OTX described in XML Schema Definitions (XSD)
One XSD for the core and each Extension
Easy validity checking
Well defined extension mechanism
Semantic description of the elements unspecified
Left to Extension provider
Core and Standard Extensions use structured prose
Intention: No manual writing of OTX documents, but graphical composing

8. OTX – Example
const int UPPER_BOUND = 10;
public procedure main() {
int sum = 0;
int counter = 0;
for counter = 0 to UPPER_BOUND
sum = sum + counter; }
showMessageBox("The sum is", toString(sum));

Benefits by using OTX:
You can easily exchange your test sequences with Tiers and other suppliers
“I want these tests to work!” (without exchanging the code)
You give your own test-engineers the possibility to choose between graphical or script implementation
You do not depend on expert programmers anymore
Independent from the concrete realization: you can either translate it into C#, Java …or execute it directly (native execution)
Abstract description guarantees reusability
