Presentation Overview

Why combined presentation?

Scenario-based and citizen-centric development

It makes the presentation more comprehensible and interesting

It saves us time to demonstrate the great work that has been done in developing prototypes and showcases

Scenario(s)

1. A service engineer in Turin has already working WSDL web services. How is it possible to make them “Semantic”?

2. He wants to set up a new service for the change of residence of a Belgian citizen who wants to move from Brussels to Turin

3. The Belgian citizen searches & discovers the service, and then invokes it

WSMO Studio

… today I’ve to develop the domain ontology that I will use to implement the PA service…

First of all the service engineer has to define the domain ontology which represents the formalization of concepts belonging to the administrative domain

So, I have to define the concepts of citizen, address, city … some important relationships between these concepts and some axioms

Inside WSMO Studio the PA service Editor can help me to define PA services following the WSMO-PA specifications hiding the complexity of the underlying conceptual model

SWSCE

We will show how existing PA services, can be composed automatically, in order to quickly develop a new one

…I have only to declare the capability and the choreography of the

desiderata service. SWSCE will tell me if the composition exist!

WSMT – Ontology Mapping Tool

Consider now the case where different public administrations export their services and the service engineer has composed some of them. The mediation problem may arise!

... mmm is it possible to orchestrate PA services belonging to different public administrations!?!? I will solve this problem by defining mediators using WSMT

As result of the composition, I’ve obtained the structure of the orchestration definition.

Now I have to define mediators!!!

GoalTree

Now we will show how to create a GoalTree used by the SemanticGov Portal in order to identify the exact service that the citizen has to execute in order to get the desired results

Now I want to make available the “change of residence” service to European citizens. The GoalTree editor will help me to define

the right questions to identify the PA Service suitable for the citizens’ needs.

Portal

Orchestration and Mediation

After discovering the right service, the citizen starts interacting with it. In turn this service orchestrates the underlying services, mediating the data when needed

Underlying Principles

Service Oriented Principle

Services: middleware services and PA services (business services)

Semantic Principle

Semantic description of business services

Problem Solving Principle

Separation of user goal and the service
