GIS as a platform for Po-BASyN A broadly interdisciplinary research project: huge amount of heterogeneous data need for high accuracy and completeness Main GIS functionalities [after Raper and Maguire, 1992]: acquisition structuration manipulation query and analysis presentation and navigation Collaboration among researchers becomes fundamental on two levels: data sharing analytical procedures sharing + the Web = WebGIS geodata sharing Towards a collaborative platform based on Web technologies

e-library In order to effectively describe contents beyond a keyword based approach, and to support effective forms of information retrieval, users must have available a domain ontology whose elements can be selected as indicators of the topics treated in the publications Example Searching for: Sicily, Bronze Age The system will retrieve the article The early bronze age Village of Mursia annotated as Mursia, Early Bronze Age partof Sicily Bronze Age Pantelleri a partof partof Early Bronze Age Mursia period place Publication: The early bronze age Village of Mursia
Historical Historical period period Thing Thing e-library Ontology The ontology has to be designed by archaeology professors and researchers with the aid of knowledge engineers. The e-library provides on-line tool to maintain and evolve the ontology.

e-library Web Interface The e-library allows content editors to describe semantically all the publications in a collaborative and simple way, by adopting a simple web-based user interface. In particular this description will be performed manually by the students, while archaeology professors and researchers will supervise the work and will progressively refine/maintain the domain ontology.

ArcheoServer.it In 2005, the chair of Prehistory and Protohistory - University of Milan, the Department of Informatics, Systems and Communication - University of Milan- Bicocca and the Department of Archaeology - University of Bologna, have started a long-term project for the creation of a set of Web-oriented services aimed at supporting the sharing of knowledge on prehistory and protohistory in Italy. The main objective is the creation of a Web portal which will provide a collaborative platform for the exchange of scientific information among the communities of Italian archaeology researchers.
