Metadata interoperability is an active research area, especially for cultural heritage collections, which consist of heterogeneous objects described by a variety of metadata schemas. In this paper we propose an ontology-based metadata interoperability approach, which exploits, in an optimal way, the semantics of metadata schemas. In particular, we propose(More)
In this paper, we propose an ontology-based metadata integration methodology for the cultural heritage domain. The proposed real-world approach considers an integration architecture in which CIDOC/CRM ontology acts as a mediating scheme. In this context, we present a mapping methodology from Encoded Archival Description (EAD) and Dublin Core (DC) metadata(More)
Temporal metadata are significant for the management of cultural collections since every object has a historical reference. The goal of this paper is to enrich collection-level descriptions with time representation and management capabilities. We obtain this by deploying a formalism called Multidimensional RDF, which enables the RDF model to represent in a(More)
Digital folklore collections are valuable sources for studying the cultural and oral tradition of a country. The main difficulty in managing such collections is material heterogeneity (handwritten texts, photographs, 3D objects, sound recordings etc.) that imposes different digitization, description and maintenance practices. A multi-layer metadata model(More)
This paper is motivated by the demand for unified access, navigation and information retrieval from the wealth of composite, distributed and heterogeneous digital cultural collections. The last years, collection-level metadata is considered to be the key of integrated access of so many resources, since they represent the inherent and contextual(More)
Information retrieval from heterogeneous resources is quite difficult and the requirement to follow a common policy permitting cross-domain searching in a variety is apparent. Since each holding institution (museum, library, archives) follows different material administration and metadata generation policies, it is obvious that information integration(More)
