Architectural Heritage semantic data managing and sharing in GIS

GIS can be effective instruments for managing Architectural Heritage data, in order to query the data for preservation purposes and to realize advanced analysis. These capabilities can be improved using some tools developed by the fields of informatics and internet services such as standards, ontologies and object-oriented programming. The official standards (languages and models) permit the encoding of data so that they can be effectively shared and integrated, concurrent with the knowledge and integration of data in Cultural Heritage (CH). Moreover, an even better interoperability of data can be achieved using open-source management software that normally features more standard data formats and can be used by everyone. These tools have been used in the research presented here for managing different kinds of data (spatial, non-spatial, images) on different views, in a unique database respecting the standards codes. In this way some schemas have been defined, and they can be exported to reach effective data interoperability.
