The aim of this paper is the implementation of a methodological workflow for the diagnosis of masonry settlings, within the HBIM approach, developing a rule-based logical inference tool in Visual Programming Language. The rule-based inferencing diagnosis is a guided process, which increases the confidence factor about settlings and actual causes, on the basis of surveyors’ technical insights and evidences. The final step is the suggestion of appropriate interventions. The results show that inference logic is directly applicable to the diagnosis problem; their efficacy depends on i) the structured parametric and data modelling of decay patterns in the HBIM model and ii) the knowledge base training. The application has been validated on a case study, Masseria Don Cataldo (Bari, South Italy).

Recent technological evolutions in the acquisition and management of building data are offering new opportunities for digital reconstruction. At the same time, the BIM (Building Information Modeling) methodology, based on the implementation of libraries composed of parametric objects provided by the IFC (Industry Foundation Classes) standard, allows the design and management of data of existing buildings, and, in particular, historical and archaeological buildings. In the latter case, the great variety of Cultural Heritage (CH) distributed over the European territory, and the ability of BIM to cover the life of buildings or/and other artefacts from a geometric, descriptive, physical and static point of view, have stimulated the development of the HBIM (Historic BIM) modelling. The HBIM approach should consider the complexity of historical or archaeological buildings or artefacts, with particular attention to possible fragmentation or incompleteness of parts. In this work, different approaches regarding the survey, restitution and data management will be described, finalised to the construction of an HBIM model, considering different possible variables, emerging from different study cases.

Introduction to the Conference Milano internazionale: la fragilità territoriale dei contesti archeologici

Since the 1970s, the development of archaeological databases has characterised the history of archaeological computing. The paper presents a summary of the pivotal early projects, with a particular focus on Italy and France, up to the current projects shared online. They are constantly monitored by the international journal Archeologia e Calcolatori, that since 1990 is an observatory of theoretical and methodological aspects of computing and information technology applied to archaeology.

Surveys conducted in the aftermath of recent earthquakes have shown that the structural and anti-seismic performances of historical masonry churches are related not only to structural damages and masonry quality but also to other key features such as effectiveness of connections, damages of wooden elements or criticalities related to humidity. Technical and scientific communities are interested in developing or improving existing procedures for the fast-visual survey and diagnostics in order to measure and analyze all the parameters affecting the building performance. In this paper a new procedure, that can be implemented in a Decision Support System (DSS) based on the Analytic Hierarchy Processes (AHP), is developed to perform a rapid visual survey and diagnostics of masonry building through a set of condition ratings. The originality of the presented work is fourfold: 1) the AHP allows to include in the analysis qualitative and quantitative data such as the quality of masonry and connections effectiveness; 2) the proposed survey and diagnostics performed by suitable condition ratings allow an extensive application in order to identify the most damaged buildings that require more detailed structural investigations; 3) the proposed AHP-based approach is integrated in a DSS to provide a powerful computerized tool, useful to large scale data acquisition; 4) the comparison with a standard diagnostics is performed to validate the procedure and emphasize the advantages of the novel diagnostics.

The Molise Region, on the Adriatic coast of southern Italy, experienced human presence since prehistoric times. Site distribution is not homogeneous throughout the region and a comprehensive census of all known archaeological sites has never been performed. In this paper, we present the results of a three-year project for the GIS mapping and database creation for all the known archaeological sites of the Molise Region. As a result, 3111 archaeological sites have been mapped, stored in a GIS database and then analysed through Spatial Analyst tools. Most of the mapped sites have been classified as area of archaeological finds (57.1% of the total sites), followed by settlements (12.9%) and buildings (9.8%). Site distribution is mainly clustered along the Biferno river valley, in the central and in the south-western sectors of the Molise Region. The largest human occupation of the region occurred during the Samnite and Roman ages. Archaeological sites are also located at different elevation a.s.l., with a general increasing trend of site elevation through time. This GIS database is, up to now, the most complete census of archaeological sites in the study area, thus representing a powerful tool to promote the archaeological heritage of the Molise Region and to address urban planning.

The paper illustrates the recent evolution of web architectures and the choices made for the web portal of ‘Archeologia e Calcolatori’. The website needed an urgent restyling to update its ASP platform, even though for 15 years it had performed its interactive work very well. Today, the ASP language is no longer supported by Microsoft and the infrastructural choices of the CNR are and will be increasingly oriented towards the world of open source and LAMP architectures (Linux, Apache, MySQL, PHP/Phyton). For this reason, a transformation was not only suggested, but vital. It was therefore decided to completely renew the website, a task consisting of about 70 physical pages to be rewritten in PHP. This work transformation has helped to pave the way for new technologies that today are modifying the web architecture of the entire WWW and that will soon allow us to implement new services and functions. Particular attention was paid to the most significant phenomena in the innovative technological panorama of Web Information Systems, with particular emphasis on the Semantic Databases and the new RIA (Rich Internet Application) technologies, the latter a splendid evolution of client-side web architectures.

PAThs - Tracking Papyrus and Parchment Paths: An Archaeological Atlas of Coptic Literature (P.I. Paola Buzi) is an ERC Advance project based at the Sapienza University of Rome. It focuses on compiling a catalogue of literary manuscripts in Coptic language, organized by their archaeological and geographical contexts. The Atlas is an open access publishing platform, built on the top of open source technologies and backed up by a web database based on Bradypus system, a MIT licensed RDBMS highly specialized in the management of archaeological and other cultural heritage data. The Atlas and the web database are being constructed to become a linking hub for automated access to the data by third party software and other applications. Specific interconnecting output formats (mainly RDF) are being developed to link this platform to other collaborative systems (such as those developed by Pelagios Commons) utilizing geographical representation, i.e. places, as a common reference point.

Archaeological stratigraphy-datasets are widely represented and visualised by the Harris Matrix. However, even digital Harris matrices retain most of the limitations their paper originals experienced and they are still in need of a standardised format for automatic recording. This paper presents an example, based on the well-known CSV open format, with a Data Package descriptor. The Harris Matrix Data Package standard is the result of two independent software implementations, one in Common Lisp by T.S. Dye and one in Python. The proposed format is not limited to describing the stratigraphy for the sole purpose of generating a diagram to look at, but it can be used to model stratigraphy as a Directed Acyclic Graph and to guide the interpretative process and integrate the results with established procedures for Bayesian modelling.

3D Heritage Online Presenter (3DHOP) is a framework for advanced web-based visual presentations of high-resolution 3D content. Developed at the Visual Computing Lab CNR ISTI, 3DHOP was designed to cope with the specific needs of cultural heritage projects, supporting web-based publishing of very high-resolution digitized results and enabling the documentation of complex restoration actions. The present paper highlights, through some case studies (Peltuinum archaeological area, AQ, and Castillo de La Muela in Consuegra), the potentials of 3DHOP’s tools for the management of data from both active (laser scanner) and passive sensors (photogrammetry and aerophotogrammetry). In addition, problems and solutions encountered during the organization and personalization of web pages will be presented. The goal of this operation is to create a three-dimensional hub that can collect and link traditional archaeological documentation to 3D geometry.
