GRID and Cultural Heritage In Mediterranean Area Giuseppe Di Gregorio, Mariangela Liuzzo, Graziana D’Agostino, Giulia La Ganga Vasta, Salvatore Scifo DAr2Ca - COMETA The research provides a digital archive of the Cultural Heritage in 20 Mediterranean Nations. The idea is that, in the past, Mediterranean populations had continuous social and cultural exchanges, beyond geographical borders and that this osmotic process, that has always brought together populations, today more than ever must be exploited. Cultural Heritage constitutes the first step in the cultural process of collaboration among populations, in fact thank to ancient culture and societies we can better comprehend different identities. The aim is to involve international scientific communities to expand and examine the database. •The basic level of the archive foresees the insertion of the results of the census of 7118 ancient Architectural and Archaeological Heritage present in Mediterranean Area. •The second level foresees the digital insertion of the data-fiches regarding 5000 cultural buildings present in Sicily. •The advanced level foresees an in-depth study regarding the Pilot Project of the Risk Map at local scale in Taormina. •Another work is the survey with 3D laser scanner of some relevant architectural and/or archaeological buildings presents in different Mediterranean nations. The defining the folders structure and the metadata schema to store and classify the digital material; then users (specialist or simple visitor) can navigate the archive and browse/search for photographs, drawings, documents. Thank to the Grid Security Infrastructure, authorized users can access to data and only special users are able to change the database. The final aim is: •To make available the results of the research all around the world; •To divulge a culture of surveying and cataloguing with advanced technology. •To create an international dialogue concerning cultural heritage.

CC. AA. at national level and received by a few districts. In Sicily this project and his attuation is edited by Centro Regionale per la Progettazione ed il Restauro. The study activity, initially, attend to three principal categories of cultural heritages: archaeological heritages, architectural heritages and containers of artistic heritages built after 1950. The Risk Map project provides a cognitive initial phase which aims at the creation of data on the consistency and distribution in the territory of the cultural heritages.The second phase concerns the survey of the vulnerability parameters of the heritages and those riskness of the territorial area.The finish phase of synthesis tries to locate the risk areas and their riskiness level and also to identify the principal parameters of decay and, at last, to assume the intervention priorities in function of the structural emergencies and the historical-artistic importance. The Map Risk project doesn’t only deal architectural and archaeological heritages, but also it develops studies and researches about the submerged heritage, the mobile object in confined environment, the demoetnoantropologic heritage, the anthropic and natural landscape.

Such archive is created on the Data Grid Services that allow to define both the folders structure to store all digital objects and the metadata schema to classify the digital material. Through a simple and efficient web interface users (visitor role) can navigate the archive and browse/search for pictures, drawings, documents. Thank to the Grid Security Infrastructure (based on the X509 digital certification), only authorized users (administrative role), can access to both data and metadata and they are able to change the status of the databases. Architecture Overview Grid offers three main service to build data driven application: the Storage Element to host Physical Files; the File Catalogue to register a Logical File Name for each file and the Metadata Catalogue to associate Descriptive Attributes (also called metadata) with every file stored on the Grid. The whole database is mapped into Metadata Catalogue and every entry will point to more than one logical files representation in order to keep trace about the relationship between archaeological data and digital objects. Point cloud Mesh Native Software Framework The Dar2ca digital archive is powered on GSAF(Grid Storage Access Framework). It is an Object Oriented framework (based on the white box model) developed to create Data Grid Application such us digital archives. It allows developers to extend applications with middleware data management functionalities. Moreover, GSAF introduces the Transaction Layer capability at client side permitting transactional operation sequence on the same dataset. Oceanographic Astrophisics Archaeological BioInformatics Grid Storage Access Framework (Data Management APIs, Vertical architecture, Knowledgment gap) GRID Middleware (Redundancy, High Availability, Backup&Recovery, High Storage Capability, Security) Transactional APIs GSAF identifies a kind of Grid Software Engineering Pattern offering a standard solution for a common problems and shared features according to the principle of the “building blocks”. It is built on top of the Grid Data Services and exposes classes and related methods that hide the complexity and the fragmentation of the several underlying APIs for applications located above.
