DATEX II v 2.3 Downloads

Reference Set Documents

The reference set of documentation defining the DATEX II specifications is downloadable from this page. This documentation set constitutes the official release of DATEX II.

The set comprises:

  • the data model and the modelling methodology used to build it
  • the XML schema and the tool used to automatically generate it from the data model
  • the exchange platform specific model.

Further useful information for understanding and using this documentation set can be found at Supporting Documentation below.

DATEX II v2.3 Release notes

DATEX II v2.3 Release notes

Attached the release notes for DATEX II reporting differences with previous official version 2.2


HTML UML Model v2.3 (browsable version)

HTML UML Model v2.3 zip (for local use)


V2.3 of the DATEX II platform independent model.

This can be viewed or managed by the Enterprise Architect Tool that canbe downloaded. In addition a browsable version of the model is also provided.

The top level entry point into the model is reached via the path "Logical:D2LogicalModel" which contains all publications, management information and exchange protocol meta-data for a DATEX II interface. Although the UML model includes other parts (Analysis, Dynamic and Functional), these are included as supporting information only and are referred to in other parts of the DATEX II reference set of documents (please see the specific specification on the Exchange Platform Specific Model).



The DATEX II Exchange Platform Specific Model (Exchange PSM) has not been updated since the release of the v2.0 documentation set. Therefore all references to the Exchange PSM in this v2.3 release documentation set refer to the Exchange PIM in the v2.0 documentation set which can be downloaded from above.

Updated WSDL for 2.3 can be downloaded here. Only change is that it refers to the 2.3 XML schema.

DATEX II XML Schema 2.3

DATEXII XML Schema 2.3

XML Schema that has been automatically generated by the XML Schema generation tool from the DATEX II UML model. The XML schema is used by PSM’s.

The Zip archive includes two schemas, one with definitions and one without definitions.

DATEX II Modelling Methodology 2.3


This is the top level entry document into the DATEX II specification set. The document describes the way that modelling is handled in DATEX II, especially focusing on the data model aspects. Data modelling in DATEX II takes a formal, metamodel-based approach that allows the process of generating the transfer syntax to be implemented in software. A tool that creates an XML schema from the DATEX II data model based on this methodology is available from this website.

The methodology also caters for user generated model extensions, which can be created either in a constrained but backwards compatible way (so called "level B" extension), or as completely new model parts ("level C") which provide more flexibility for the price of losing compatibility to the standard model (referred to as "level A"). A feature that is actually more related to the tool than to the methodology itself - but that is also briefly described in the Methodology document - is the possibility to deselect optional features during XML schema generation, which allows for application/service specific Profiles, which are fully upwards compatible to the full schema.

DATEX II Profiling guideline

Profiling guideline

The DATEX II information model is a vast model for all kinds of information that is possibly exchanged in the traffic and travel domain. In operational practise the implementers of information links focus on parts of the model only, as these parts are relevant for their operational exchange requirements.

To manage this focus and in order to ensure the standardisation of subdomains, the concept of profiling is developed. In this guideline the way a profile can be defined to support a specific information link, is provided.

DATEX II Parking as submitted to standardisation

TC 278 prCEN TS 16157-6 E DRAFT

TruckParking Profile

This document is submitted to CEN to be standardised as Part 6 of CEN Technical Standard 16157. The document itself can only be available on this website as long as the formal CEN standardisation process runs.

The document containing the standard is very extensive and detailed. Therefore more accessible documentation will be created and published on this website later on.

The PIM part is included in version 2.3 that can be found in the Reference Set

In ANNEX A the profile for Truck parking can be found.

In the file: the xml schema's for static and dynamic truckparking can be found.
