Dear Liliana, The University of Pavia used Topic Maps in a small (about 1600 topics and 4000 associations) project for a census of the cultural patrimony located in the mountain community of the province of Pavia (a sort of ethnographic documentation center). See CeDECA (Centro di Documentazione Etnografica e di Cultura Appenninica) http://www.cedeca.it (I'm sorry but it's only in italian). Best Salvatore VassalloReceived on Mon Jun 08 2009 - 06:00:05 EDT
