MapFish Framework has been used by the Joint Research Center of the European Commision to create a prototype INSPIRE Geoportal and allows the discovery and viewing of spatial data sets.
The INSPIRE Geoportal provides the means to search for spatial data sets and spatial data services, and subject to access restrictions, view and download spatial data sets from the EU Member States within the framework of the Infrastructure for Spatial Information in the European Community (INSPIRE) Directive.
Hi is the MapFish INSPIRE prototype sourcecode available publicly?
Camptocamp didn't created this application, so I can't answer, sorry
