rating system. In addition, we made available an environment to be used for the
execution of queries on the data. To show the feasibility and ready-to-use approach
we employed, this chapter discussed the design of a currently in production web
portal. Within the portal, not only are the data and related ontology published,
but also a set of demonstrative applications are provided. These applications can
be used by citizens, enterprises, and also PAs to easily obtain contact information
of PAs. We believe the experience we reported in this chapter can facilitate PAs in
meeting transparency, accountability, and semantic interoperability requirements,
and it can serve as a guide for other PAs that wish to effectively open their data. All
the administrative processes that now rely on IPA can be, in the future, based on
the created Linked Open IPA.
We consider the presented work a starting point toward the creation of a com-
plete SPC “web of data.” Therefore, a number of activities are planned in this
direction. First, we are currently assessing the possibility to transform in RDF the
data of another base registry managed in the context of SPC. This registry includes
Italian geodata. The data can be potentially connected to IPA since PAs can feed
the registry only once they are registered into IPA. Finally, we are planning to
enhance the web portal to (a) add other data sets, (b) develop further applications
that demonstrate the added value of the LOD approach and from a user interface
viewpoint, (c) address navigational issues of the data sets (e.g., using tools such as
ELDA; Epimorphics Ltd., 2012), thus further improving the user experience. At
the moment, three different applications (one desktop and two mobile) are devel-
oped using SPCData content through its SPARQL endpoint.
