Ricerche archeologiche sul campo e archivi digitali: il manoscritto di Ercole Nardi

The article presents some aspects of the research project which has been carried out in the middle Tiber Valley (Sabina Tiberina), to analyse the distribution of archaeological sites in the territory, based on new field surveys and the study of archive documents ("Progetto Galantina"). The research takes advantage of the positive experiment conducted by the Istituto di Studi sulle Civiltà Italiche e del Mediterraneo Antico (ISCIMA) of the Italian CNR to set up and integrate within a Geographical Information System a new model of archiving, managing and querying archaeological information, focused on the analysis of excavation diaries and their SGML and XML encoding. The implemented system gives rise to a many-sided repeatable digital model, easily exportable in various situations. The integration between the DTD established to formally describe archaeological data and the elements of the TEI Lite and Dublin Core standards makes it possible to record and query data coming from both published excavation reports and archive documents dating from the nineteenth century, which deal with the description of archaeological itineraries around Rome. The example presented in this paper refers to the manuscript by Ercole Nardi "Ruderi delle Ville Romano-Sabine nei dintorni di Poggio Mirteto" (1885) and is aimed at preserving archaeological information through digital supports, electronic exchange formats and especially reliability of the information integrity. Moreover, it makes an attempt to experiment and develop new forms of knowledge diffusion which are more suitable for interactive web consultation than passive reading.
