Semantic excavation of the city of books

As the SemanticWeb gains momentum, so grows the interest in making knowledge kept in various repositories available. In this paper we describe a case study using a methodological approach for porting cultural repositories to the Semantic Web. The approach consists of thesaurus conversion, meta-data schema mapping, meta-data value mapping, and thesauri alignment. It is derived from our experience collected in a number of conversions we have performed for the E-Culture project, and in this paper we apply it to a collection of data about images related to book printing.
