and aligned with European Interoperability Frame-

draws primarily the concepts of technical, organiza-
tional and semantics interoperability.
8 ROAD MAP TO EG MODEL
The architecture support to Extended Government de-
scribed so far is being issued in accordance with an
incremental plan. PDD in particular has already been
issued in production, while all other components are
being deploed. To give an indication about roadmap
progress in terms of Extended Maturity Model Gov-
ernment we can say that Lazio Region is located at
Level 2 of the MM.
8.1 CO System experience
Regione Lazio is committed in a national project
called Comunicazioni Obbligatorie (CO) that con-
nects Central Administrations, Regions and Provinces
by a net with the goal to replace the old modes used by
public and private employers to communicate hirings,
modifications and ends of job relationships to Cen-
tri per lImpiego (CPI), Enti Previdenziali and Minis-
tero del Lavoro (MIL). All services required for the
project were developed according to SPCOOP guide-
lines, with particular reference to the use of PDD
as WS Gateway. Regione Lazio participated in the
CO System using its PDD. In the first five months,
1.570.570 service requests reached PDD-RL, as sum-
marized in Figure 4.
8.2 Lesson Learned
Regione Lazio experience raises an issue: realization
of A2A and A2B isolated processes leads to frag-
mented knowledge and to a loss of fundamental in-
formation used to integrate management relationship
between Administration and citizens or enterprises.
For this reason, LAit S.p.A. and Regione Lazio have
planned a KMS design with basic concepts (see Sec-
tion below) inspired both to EE model and EG model,
in order to devolop research ideas in the EE field.
9 FUTURE DEVELOPMENTS
Industrial and research worlds are thus sharing the
same views and aims, colliding towards a new web
vision, where knowledge is no more a huge amount
of (semi)structured text but is turning into a cloud
of overlapping concepts, topics and domains. At the
same time, a better organization of the huge amount
of information erupting from the stream of available
technologies is needed. To find the way through
the plethora of information sources, differentiating
in content, presentation and accessibility, a viable
approach would be necessary to make these layers
explicit, allowing users to recognize them as sev-
eral possible manifestations of the same knowledge,
and organize them accordingly. It makes sense to
move from single (and ininteroperable) specific ser-
vices (blogs, wikis, forums, discussion groups and so
on) to huge collectors of information on a open and
global scale. Knowledge Management Systems fu-
ture (KMS, from now on) should provide the main
intellectual stream of interests around which knowl-
edge should be organized (and different services be
offered). By adopting Semantic Web standards, KMS
would be developed around ontological repositories
of conceptual knowledge, which will be used as ref-
erence vocabularies for accessing contents of feder-
ated (or simply annexed) services and (socially) book-
marked web pages. In this scenario, traditional ser-
vices will still be reusable and will coexist with their
new semantic counterparts, with the former being se-
mantically annotated with respect to the ontologies
adopted, and the latter natively supporting a seman-
tic organization of their content.
The main principles of KMS should be:
• Affordable setup: no more heavy bulked Social
Networks held by major company titans. As a
normal web user can now start a forum or a blog
using third party (often free) software, he should
also be able to use a web host or a hosting service;
• Accessible by (Semantic?) Search Engines: in our
vision, this is surely something related to the open
nature of KMS, but it would gain some commit-
ment from search engines, which will be able to
improve quality of searches through proper index-
ing of published semantic annotations;
• Scalable open architecture: a given service may
explicitly be built upon a KMS, committing to its
ontologies and content organization. Viceversa,
in an even more open view, independent services
may be linked by a given KMS. This would allow
users to tag the content of these services accord-
ing to the oasis reference ontologies, thus easily
putting traditional (non semantic-driven) services
immediately into practice. The same would be ap-
plied to standard web pages. People could write
web pages directly connected to a KMS making
explicit reference to its vocabulary, as embedded
RDFa, or they could semantically bookmark an
