2. Xpose
What is it?
Comes from:
Ex·pose' To set forth; to set out to public view; to
exhibit; to show; to display;
“Xpose is an extensible data processing and
distribution platform for fast development of ITS
applications”

3. Xpose
What does it do?

Xpose uses all available real-time data sources, validates, filters
and transforms them to a single unambitigous data representation of
the traffic [incident] status.

Xpose is able to process all data in real-time and check it against
freely defineable Business Rules. Depending on the result, Xpose
can inform people and/or organisations and can activate external
processes by means of electronic messaging

Xpose can visualise the harmonized internal model through “web”
application [s] or can transform and export the data for further [offline] processing.

5. Xpose
Architecture

Xpose uses an open application framework based on open standards and is
implemented as open-source software as defined in the recommendations for the
“Interoperable Delivery of European eGovernment Services to public
Administrations, Businesses and Citizens” (IDABC)

The Xpose datamodel is based on different [international] standards related to
Traffic- and Incident Management entities.

Xpose uses an industry standard object relational mapper for storage of all the
managed entities

Xpose uses an efficient object oriented pattern matching algorithm for its real-time
data processing.

Xpose can use different messaging technologies to interact with external systems.

Database

The platform supports different commercial and open-source databases such as Oracle,
MySql or SqlServer, and …

.. can use spatial extensions for a number of databases, supporting most of the OGC
Simple Feature Specification.

.. has automatic entity auditing which helps to evaluate the full registration process.

.. has dynamic permission-based access, which provides pessimistic locking only when
necessary,

.. uses versioning for all data-dictionaries, providing support for dynamic and planned
configuration changes,


6
.. includes full text search features for most non-formatted free-text fields,
.. has special tools for import and export of configuration data.

Decision Support


The rule-engine works with a user-managed set of business
rules.

The rule engine has full access to all dynamic and stored data
and “reasoning” can be started dynamically or at specific time
intervals,

The outcome of the rule engine can be “chained” to reason
over other sets of business rules,

.. and can be used to start specific [new] business processes
through the workflow module,

7
The platform is fully integrated with an object oriented rule
engine, which provides real time decision support
.. and can also be used to trigger communication channels of
the platform such as eMail or SMS or execution channels to
control external devices.

8. Xpose
Workflow


A [business] process is composed of
activities that are connected with
transitions. Processes represent an
execution flow. The graphical diagram of a
process is used as the basis for the
communication between non-technical
users and developers.

8
The platform is fully integrated with a
flexible user-managed Business Process
Management Suite ,
The platform provides the integration of the
workflow module with the other modules.
The business processes have full access to
all data and services and can interact with
them.

9. Xpose
Export


The platform is integrated with a
standard reporting engine and an
external reporting design tool, which
allows for reporting in different formats
such as PDF.

9
The platform provides export
functionality in different industry
standard formats such as XML, Excel or
plain Text,
The platform uses a de-facto charting
library to create user-friendly
presentation of data.

10. Xpose
Presentation


… with for instance full drag-and-drop
support,

.. and map-based views which enables
the user to experience data “in its
geographical context”

10
Xpose uses a standard presentation
component which provides desktop-like
single-screen applications,
The presentation component is normally
used in a “conversation scoped ” context,
which substantially simplifies the
implementation of a single Use-Case.

A real application demonstrates the full potential of the platform. We’ve implemented the
core of Incident-Management, it
.. includes the management of newly added IM-related objects such as Centre ,Event ,
EventType, Caller, RoadSegment, RoadLocation etc.
.. has real-time location handling for parsing and validating the user-provided event
location and [rule-based] event location cross-checking to identify possible double
registrations,
.. implements the full chain of Incident Management from the first registration up to the
administrative closure,
.. Includes [drag-and-drop enabled] resource- and traffic-measure management
.. includes real-time [rule based] Performance Indicator (PIN) analysis
.. includes [drag-and-drop enabled] causality which is the relationship between an event
(the cause) and a second event (the effect),
..has a SitRap function which produces an event status report in PDF-format
