Item LIDO and CRMdig from a 3D Cultural Heritage Documentation Perspective(The Eurographics Association, 2010) Pitzalis, Denis; Niccolucci, Franco; Theodoriou, Maria; Doerr, Martin; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThe most important characteristic of Digital Libraries is their flexibility in exposing content. Typically a DL provides a search interface which allows resources to be found. These resources can be local or remote, depending on how the data are organised within the DL and on how these data are made available for harvesting from/to other DLs. This kind of communication is possible because the structures of different DLs are expressed in formal specifications. In particular, especially in Cultural Heritage where we need to describe an extremely heterogeneous environment, some metadata standards are emerging and mappings are proposed to allow metadata exchange and enrichment. The CIDOC-CRM is an ontology designed to mediate contents in the area of tangible cultural heritage and it is ISO 21127 : 2006 standard. In particular an extension of the CIDOC-CRM, known as CRMdig, enables to document information about data provenance and digital objects in a very precise way. LIDO is a rich metadata schema suitable for handling museum-related data, still under development but very promising. In this paper we propose an update of the CIDOC-CRM to LIDO mapping and using a case study we will compare how CIDOC-CRMdig and LIDO handle the digital information of an object.Item Semantic Enrichment of Geographic Data and 3D Models for the Management of Archaeological Features(The Eurographics Association, 2010) Felicetti, Achille; Lorenzini, Matteo; Niccolucci, Franco; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThe present paper describes various technologies to link semantic information to 3D models during the process of management of 3D data and geometries used by the archaeologists for the reconstruction of ancient monuments or sites. This is an important requirement for the purposes of modern research since, although we have a lot of good 3D models of topographic objects, it is often difficult to make computers aware of the nature of the related real object (buildings, sites or landscapes) or parts of them (e.g. a column capitel and its various elements). The same difficulties occur when it is necessary to link geographic information to 3D models or to deal with metadata and annotations concerning the same elements, for which semantic technologies are required. We propose a possible way to integrate 3D data in a geographic environment and in addition to enrich 3D models by providing a set of semantic descriptions for each geometrical component of a given object, extended with semantic annotations of the model as a whole or of specific parts of it. The proposed technology is based on the use of various standards, including GML and one of its application schema, CityGML, specifically designed for the representation of 3D urban objects, and CIDOC-CRM, the cultural heritage ontology suitable for every non-structural description of each topograhic object or building, including temporal entities (events).Item AnnoMAD: A Semantic Framework for the Management and the Integration of Full-text Excavation Data and Geographic Information(The Eurographics Association, 2010) Felicetti, Achille; Samaes, Melissa; Nys, Karin; Niccolucci, Franco; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThis paper describes the advances in the development of the AnnoMAD System, a modular framework created by PIN and The Cyprus Institute for the management and the integration of free-text archaeological data and geographic information related to excavations. The system provides a free-text encoding tool able to annotate textual documentation using semantic features and a GIS integrated framework to capture the spatial descriptions and make them available in a geographical context. AnnoMAD is built using Open Source software. It leverages on the flexibility of CIDOC-CRM and RDF to create a layer of semantic metadata to be linked to the original documents, in order to preserve their integrity. Integration of the GML standard geographic language with CIDOC-CRM guarantees data interoperability and demonstrates that CIDOC-CRM can offer a valid schema that may be easily extended to incorporate geographic features and relations. AnnoMAD has been applied to a case-study concerning a Bronze Age excavation in Cyprus, the Hala Sultan Tekke archaeological site.
