CIPA 2005 XX International Symposium. 26 September - 01 October. 2005. Torino. Italy 
describing the entity selected, as for example an historic 
monument. 
As mentioned in paragraph 2.1, the management of data on the 
dynamic map are passed through MapServer system and then 
elaborated by Java Engine to be prepared for Web visualization 
as HTML page. Descriptive cards are generated by Java Engine 
also, but the repository of reference is based on SDX system, 
that is connected to Postgres Database. From SDX are then 
directly generated the pages that are result of searches 
introduced in Web site. In this case the functionality is similar 
to a classical textual search engine. 
2.3 Web presentation and Site Flow 
The navigation flow of a Website is fundamental for interest 
that can be received from users and an easy structure of the site 
is one of the most important requests from Internet users. 
For this purpose, the project of Website structure was discussed 
and decided with the researchers of cultural part, with the goal 
to find the optimal specifications for navigation flow inside the 
Website. 
To improve interest in the data contained in P.I.C.A. it was 
decided to develop a didactic section, accessible from any web 
page. As mentioned, the project is in fact addressed to general 
users also, not necessary experts of the disciplines contained in 
P.I.C.A.. For this reason several didactic pages have been 
implemented to explain terminology, keywords and the parts of 
the site that were selected to be more useful for schools or for 
simple tourist usage. Specific tourist information have been 
integrated to the description of the entities contained in P.I.C.A. 
(accessibility of cultural sites, opening times of monuments, ...) 
and these information has been completed with simple 
explanations of P.I.C.A. contents. 
P.I.C.A., the possibility to have in the same time and with the 
same access different types of information. 
Figure 4. Entity Description Page 
In upper left part of the page it is possible to choose to enter in 
these more specific information and the sections are named for 
example Documents, Photo Gallery, Specific Analysis, Tourist 
Information, ... 
In the lower left section of monument card it is possible to 
access to didactic pages (Figure 5) that explain arguments 
connected to the entity described in the card. An interesting 
characteristic of these pages is that have been implemented 
using a simple language and a large use of illustrations has been 
done, in particular using picture made by hand with drawings 
technique, obtaining an appealing presentation of arguments.

Figure 3. P.I.C.A. Homepage 
From the homepage (Figure 3) it is possible to choose the 
region where to work and to have access to the dynamic map 
where to select the entity of interest; from the homepage it is 
also possible to insert a specific research and to directly use 
P.I.C.A. search engine. 
On the map it is possible to use all the powerful facilities of 
MapServer that will be described in section 0 below and to 
choose the entities on which to have specific information. 
The card that describes for example a monument (Figure 4) has 
been projected to have basic information in the first page that is 
visualized to user, but it is possible from this first page to access 
more specific data connected to entity. These information can 
be both tourist and technical for expert people (researchers) 
usage. In this manner is reached one of the main goals of
