Introduction
Data exchange among centres is a baseline service for implementing intelligent transport system
(ITS) services. For interoperability purposes, data delivery and collaborative ITS services need to be
implemented according to certain specifications based on fully-described interfaces. The functional
exchange profiles implementing push and pull exchange patterns aim to guarantee timely and reliable
delivery of information, based on a defined level of service and user requirements. These depend on
application level. A variety of options for implementing exchange are therefore described. These enable
several interoperable exchange patterns with required features to fully satisfy user requirements:
from Snapshot Pull/Push to Simple Push to Stateful Push, also considering a service request/service
feedback collaborative ITS services business scenario, which allows interoperable exchange among
any number of interconnected and collaborating elements to implement traffic management and traffic
information services orchestrated among several ITS actors.
This document aims to define and describe the requirements on XML messages for implementing
messages using XML Profile B. In particular, it is intended to be used in platform-specific implementations
using simple object access protocol (SOAP) web services to enable DATEX II (EN 16157-1) XML coded
messages for Snapshot Pull, Snapshot Push, Simple Push and Stateful Push. It is additionally relevant
to collaborative ITS services (CISs) such as Simple CIS and Stateful CIS exchange patterns with relative
functional exchange profiles as described by ISO/TS 19468. Figure 1 describes the relationship between
exchange-related documents.

The message structure defined in this document refers to the "basic exchange data model" and derived
data dictionary defined in ISO/TS 19468:2022, Annex C, which is implemented in XML schema by the
DATEX II methodology defined in EN 16157-1.
This document is not intended to conflict with existing standards on interfaces of data exchange among
ITS centres.

Intelligent transport systems — Data interfaces between

This document, based on ISO/TS 19468, specifies a platform-specific method for implementing data
exchange among centres based on simple object access protocol (SOAP), supporting the EN 16157 series
(DATEX II) for Push/Pull data delivery and service request/feedback collaborative intelligent transport
system (ITS) services.
This document defines the message rules and procedures for communication between transport
information and control systems using XML (Profile B).
This document clarifies how to package end-application messages and relevant data.

payload delivered in the messages are beyond the scope of this document.
Rules and procedures for exchanging data-packets in lower communication layers are also out of the
scope of this document. These functionalities can be implemented using generic protocols defined in
the industry standards. However, this document does define how to use these protocols.

This document describes the mapping rules in order to implement specific platform Push and Pull
and collaborative ITS services (CIS) FEP+EP-based PIM in SOAP web services technology PSMs. PIM-
level descriptions of FEP+EP are detailed in ISO/TS 19468; the relevant clauses are referenced in this
document.
6.1 Web services definition and options
Web services (WSs) provide standard means of interoperating between different software applications,
running on a variety of platforms and/or frameworks. A full definition for "web service" can be found
in Reference [6].
Web service definitions offer several options. Table 1 shows the options chosen by the PSMs described
in this document.

Security The security set-up shall be decided by the supplier, should be ne-
gotiated with the clients, and is outside the scope of this document.

starting the data exchange.

at FEP+EP PIM level as UML collaboration and sequence diagrams in ISO/TS 19468 clauses to the
corresponding SOAP web service definition language (WSDL) methods and data structure.
6.3 Security aspects related to WS implementation
As described in ISO/TS 19468, security aspects are considered in the exchange specification framework
in the general context diagrams, under the aspects of communication features. Security features are
described in ISO/TS 19468:2022, 5.7, while security requirements are defined in ISO/TS 19468:2022,
Annex B.
As this document is based on exchange communication among centres based on XML, Profile B (e.g.
under SOAP webservices and supporting DATEX II), security for such exchange framework based on WS
may rely on the WS-security OASIS international standard specification which is widely used within
several frameworks (e.g. the JAVA wsse4j, jax-ws, or the .NET WCF). Some aspects of WS-security are
also introduced in ISO/TS 19468:2022, Annex D.
The WS-security framework is composed by profiles that define the interoperability rules to be
used to attain specific features. Those profiles tackle the necessity to exchange an identification and
authentication token (e.g. the username token profile), or how to use XML digital signature (XMLDSG)
and XML encryption (XMLENC) to sign and encrypt parts of a SOAP message, respectively, or to support
complex scenarios through the combined use of security assertions markup language (SAML) tokens
and potentially extensible access control markup language (XACML) access control policies.
WS-Security needs further profiling before its use which is, usually, policy specific (e.g. which algorithm
and cipher-suites to be used, canonicalization algorithms, token layouts, compliance with WS-BSP, etc.).
This profiling effort which can be specifically based on regional or project specific rules, is outside the
scope of the current specification.
