A 3D-based web platform for multi-source diagnostic data fusion and visualization
Belfiore Cristina Maria, Callieri Marco, D'Agostino Graziana, Menta Salvatore, Potenziani Marco, Santagati Cettina, Scopigno Roberto
Cultural Heritage conservation increasingly relies on the integration of diverse diagnostic data acquired through multiple techniques. However, managing together these data, often heterogeneous in format and origin, remains a significant challenge. Starting from this premise, we introduce a web-based platform designed to support data fusion and visualization of multi-source diagnostic analysis. Designed by a multidisciplinary research team and developed exploiting open-source technologies, the platform enables interactive access to diagnostic results through annotated 3D models, allowing users to interrogate specific areas of interest, retrieve the associated analytical data, and share them in several ways. A key feature of the platform is its JSON-driven data management system, which associates each diagnostic analysis with a specific template composed of atomic fields easily adaptable to the requirements of various analytical methods. The platform was validated through a case study on the historic mortars of a prominent 18th-century building in Catania (Italy), a context characterized by visible degradation and partial loss of plaster, ideal for sampling and analysis. Diagnostic data were acquired using a range of techniques (including XRPD, FTIR-ATR, WD-XRF, and POM) and complemented with 3D surveying methods, resulting in a rich dataset comprising both metric and analytical information. The study confirmed that fusing heterogeneous datasets within a unified system can exemplify a data-driven approach to heritage diagnostics, while the ability to annotate models and link them to specific diagnostic entries can add a layer of semantic richness crucial for interdisciplinary interpretation.Source: INTERNATIONAL ARCHIVES OF THE PHOTOGRAMMETRY, REMOTE SENSING AND SPATIAL INFORMATION SCIENCES, vol.

The science laboratory in the Museum: the latest scientific analyses on the cotton cemí and new research perspectives
Boano R., Mangiapane G., Pennacini C., Ostapkowicz J., Morigi M. P., Bettuzzi M., Seracini M., Pingi P., Potenziani M., Buti D., Magrini D.
The Museum of Anthropology and Ethnography of the University Museum System at the University of Turin (MAET) houses a unique cotton reliquary in its collection, enclosing a human skull dating back to the 15th century and originating from the island of Hispaniola (present-day Dominican Republic/Haiti). This is the only surviving pre-Columbian cotton cemí (a representation of an ancestor or spirit) presently known. The object offers a rare glimpse into the complex rituals and belief systems of the Taíno, the Indigenous people of the Greater Antilles on the eve of European contact. The artefact was recovered from a cave west of Santo Domingo and acquired in 1882 by the Italian consul Giovan Battista Cambiaso, who sent it to Italy before 1902. It was later donated, along with a second wooden cemí, to the Museum of Antiquities in Turin in 1928, and subsequently transferred to the MAET. The cotton cemí represents a seated figure approximately 75 cm in height. A portion of a human skull is embedded within the head. While cotton forms the outer surface of the cemí, its internal structure is composed of various materials. In 2022, with the support of the national node of E-RIHS (European Research Infrastructure for Heritage Science), a team from the University of Turin conducted a series of analyses on the artefact. In October 2022, three multidisciplinary E-RIHS teams belonging to the Molab (MObile LABoratory platform of the infrastructure), equipped with advanced technical instruments, collaborated with researchers from the University of Turin to produce a digital reconstruction of the cemí’s surface and internal structure using non-invasive techniques. The project also enabled advanced chemical characterization of the surface materials and a thorough assessment of its conservation status. The techniques employed by MOLAB included visible, IRR, and UVL imaging; X-ray tomography combined with 3D laser surface scanning; and external material characterization through FTIR, UV-vis-NIR reflectance, XRF, and Raman spectroscopy. The data collected offer new and exciting insights into the materials and manufacturing techniques, which are now available to both specialists and the broader public. In 2023, the TAZEBAO project was launched as part of the PNRR Extended Partnership “CHANGES: Cultural Heritage Innovation for Next-Gen Sustainable Society,” specifically within SPOKE 4, “Virtual Technologies for Museums and Art Collections.” Developed by the University of Turin in collaboration with the immersive communication agency NOREAL Interactive, the TAZEBAO project aimed to create a flexible and accessible digital system to enhance the value of the University of Turin’s museum heritage. It integrates scientific and narrative content with highly innovative physical and virtual experiences. Among the three prototypes developed, the one dedicated to the cotton cemí allows users to explore the artefact through a digital twin and an immersive virtual reality narrative. The entire platform is designed to adapt to various devices and users, promoting inclusivity and enabling the configuration of personalized interactive experiences. The digital twin prototype of the cotton cemí was conceived as an immersive and accessible experience, presented within a traveling exhibition composed of modular panels and an interactive totem, easily transportable and installable in any indoor space of at least 25 square meters. At the heart of the project is the digital twin, which can be explored via touchscreen, and VR headsets that narrate the animated story and historical-anthropological context of the cemí and its provenance. The high-definition 3D model, based on photogrammetric and tomographic techniques, includes both the external shell and the internal structure containing the human skull and its supporting elements. The user interface was designed to ensure inclusivity, with interactive commands accessible to users with disabilities and multimedia content available in Italian, English, and Spanish. A mobile version is also available via QR code, while the entire system operates offline and anonymously records usage data. The source code, released under an open-source license, allows for free dissemination and adaptation of the project in other museum contexts. The project was conceived in the spirit of digital restitution, aiming to reconstruct and enhance the biography of the cemí, from sacred object to cultural heritage subject to scientific research and interpretation. An international committee of experts in Taíno art, history, and culture contributed to the project1. Through this process of valorization, it becomes possible to promote a symbolic restitution of the artefact at the international level, fostering digital, educational, and scholarly engagement, and encouraging further multidisciplinary research. In this perspective, the MAET has assumed the role of cultural and scientific mediator, promoting a new narrative of the object through the use of innovative technologies. This broader perspective aligns with the ongoing debate on the decolonization of ethnographic collections, with its attendant ethical, historical, and scientific implications. This catalogue brings together contributions from experts in pre-Columbian Caribbean civilizations, Taíno collections, and scientific research conducted on the cotton cemí, with the aim of offering a comprehensive contextualization of the history and characteristics of this extraordinary artefact.Project(s): Cultural Heritage Innovation for Next-Gen Sustainable Society, European Research Infrastructure for Heritage Science

ARIADNEplus Visual Media Service 3D configurator: toward full guided publication of high-resolution 3D data
Potenziani M., Ponchio F., Callieri M., Cignoni P.
The use of digital visual media in everyday work is nowadays a common practice in many different domains, including Cultural Heritage (CH). Because of that, the presence of digital datasets in CH archives and repositories is becoming more and more relevant. However, the correct management of these assets, specialized and often complex, it is not always trivial, especially for communities of users lacking specific training. In these cases, systems enabling assisted data management during the different phases of their life cycle, can be a solution. The Visual Media Service (VMS) is a web-based platform that enables the easy publication of complex visual media assets, specifically targeting the CH domain. It allows users to upload high-resolution images, RTI (Reflectance Transformation Imaging) images, and 3D models, transforming them into an efficient format for interactive web visualization. The VMS is an end-to-end solution able to support the entire publishing process, from data uploading to presentation customization. To expand its adoption in the CH community, the ARIADNEplus project aimed to enhance its features, providing innovative services for archaeological data publication. This paper introduces the VMS 3D configurator, a new tool designed to improve the visual organization of 3D archaeological datasets in the VMS. The configurator guides content creators through a multi-step wizard, offering customization options for the presentation of 3D models. The configurator consists of five different configuration stages, each providing specific customization features, such as model orientation, appearance, scene navigation, viewer interface, and annotation of points of interest. In addition to provide a detailed description of all the configuration possibilities, the paper will also discuss uses, limitations, and potential developments of the 3D configurator, and of the entire platform too, highlighting the value of the VMS as a tool for publishing, exploring, and disseminating CH data.DOI: 10.5281/zenodo.8075050

Designing and developing interactive kiosks for cultural heritage: best practices and common issues
Potenziani M., Callieri M., Cignoni P.
Interactive kiosks are a smart way to engage museum visitors and complement their visiting experience with another layer of engagement and interaction with the artworks. Kiosks are also a perfect complement to an integrated Cultural Heritage project that applies digital technologies for the study, the documentation, and the conservation of works of art, as it might help in adding a new dimension of dissemination and public outreach to the project. The design and development of an interactive kiosk for Cultural Heritage involves very different knowledge, skills, and tools. However, it is possible to find various software components that can be used, with a reasonable effort and a sound strategy, to set up an interactive kiosk able to display complex 2D+ and 3D data and implement advanced interaction paradigms. The aim of this work is to help possible developers, by discussing some working strategies and approaches, highlighting possible tools, and analyzing past activities of kiosk development and deployment.Source: SPRINGER SERIES ON CULTURAL COMPUTING, pp. 473-497

3D imaging application to the study of the early Neolithic ceramic complex: the decorated pottery of Rio Tana (Abruzzi, Italy)
Petrinelli Pannocchia C., Vassanelli A., Terranova A., Potenziani M., Pingi P., Callieri M., Cignoni P.
This study aims to demonstrate the potential of 3D analysis in the study of prehistoric ceramic complexes. Due to the production systems used, prehistoric pottery decorations can vary significantly. Examining the frequency of various decorative methods used at different sites may help identify areas potentially connected to specific traditional elements. However, this is usually a cumbersome and time-consuming task. 3D digital methodologies can bring several advantages in the interpretation of ceramic decoration, providing newtools that can improve analytical skills, speed up the decision process, and support the researcher’s conclusions. This work focuses on the application of these methodologies to the study of decorated ceramics from the Neolithic site of Rio Tana (Abruzzo, central Italy): firstly, a pottery complex from this site has been 3D digitised; then, an interactive and web-based 3D visualisation system has been developed to enable access and study of these digital data. By comparing archaeological data with experimental data, in parallel with the analysis of 3D models’ surfaces, it has been possible to better define the technique employed and quickly identify the type of tool used to create the ceramic decorations. Furthermore, the web-based system made it possible to share and disseminate the digital dataset with the community, creating the conditions to make it easier to compare the frequency of different decoration methods and tools used at Rio Tana with other sites.Source: THE EUROPEAN PHYSICAL JOURNAL PLUS, vol. 139 (issue 6)

CHANGES - D5.1 Report on data encoding-integration-processing needs of CH stakeholders
Scopigno R., Potenziani M.
This report is part of the work planned in the project PNRR PE 5 “CHANGES”, and specifically in Spoke 5 “Science and Technologies for Sustainable Diagnostics for Cultural Heritage”, WP5 “Digital technologies, AI/ML solutions, chemometric methods supporting data-driven Heritage”. It implements one of the results planned in the project: R5.1 – Study of CH stakeholders' needs concerning data encoding/integration/processing – M12 and constitutes one of the Deliverables: D5.1–Report on data encoding/integration/processing needs of CH stakeholders. The scope of this report is to collect, discuss, and organize the needs of our stakeholders (museum curators, conservators, restorers, art historians, ...), to highlight how they need support in terms of enabling digital data types, digitization processes, and digital platforms/tools. The results of this preliminary study will steer the design of the tools and technologies developed in Spoke5-WP5. The Cultural Heritage (CH) context is very broad, both in terms of preservation goals and subjects (ranging from a small artifact to an entire building, up to an archaeological site or an entire city) and in terms of research/conservation questions (which, in turn, often require different representation approaches, media, scales, and accuracies). For this reason, we have first to introduce some concepts and distinctions between the different digital approaches to CH management, and then we will present the results of a questionnaire aimed at collecting information and needs from potential stakeholders. The final goal is to use this knowledge to guide the process of designing new digital tools aimed at supporting our community.Project(s): Cultural Heritage Innovation for Next-Gen Sustainable Society

Cultural Heritage 3D data on the Web: issues and perspectives
Potenziani M, Ponchio F, Callieri M, Cignoni P, Scopigno R
Les modèles numériques 3D sont unanimement considérés comme un atout inestimable pour l'étude, la gestion et la promotion du patrimoine culturel. L'urgence de COVID-19 a accéléré la tendance commune à travailler à distance et, pour le patrimoine culturel, la présentation, le partage et l'accès aux données 3D en ligne sont désormais perçus comme une nécessité. Malheureusement, l'absence de méthodologies, d'outils et d'infrastructures standard rend difficile le passage du stockage local à la gestion en ligne de données 3D complexes. Dans cette contribution, nous souhaitons évaluer l'état de l'art de l'utilisation avancée de la 3D sur le web, en soulignant les besoins actuels, en présentant quelques études de cas et en explorant les perspectives futures.

ARIADNEplus D15.2 - Final report on ARIADNEplus services
Marberg Jf, Bardi A, Vlachidis A, Meghini C, Binding C, Tudhope D, Sinibaldi F, Ponchio F, Mangiacrapa F, Radmanlivaja I, Callieri M, Potenziani M, Lamé M, Assante M, Pagano P, Hermon S, Vassallo V
This deliverable describes the activities carried out within Work Package 15 (WP15) of the ARIADNEplus project by the different partners and describes the results achieved. The work package consists of several individual tasks and subtasks with the overall goal to develop and provide useful services to archaeologists. This means the work package is by nature heterogeneous with stand-alone tasks and services. Efforts have been made to facilitate collaboration between the individual tasks through joint work package meetings. This has resulted in new cross-task contacts being made, and some sharing of expertise to improve services has been done. A service design template aligning the ARIADNEplus services with the requirements from European Open Science Cloud (EOSC) has been created. In connection with this, the ARIADNEplus AO-CAT ontology has been adapted to the requirements from EOSC Resource Data Model (Task 15.1). The Visual Media Service (Task 15.2.1) has had a new format added, allowing for 2D visualisation of LIDAR data in DEM format. In addition, three other standards have been added: gITF, ThreeJS and IIIF, supporting various functionality in the service. The service has also been adapted to support integration with the ARIADNEplus infrastructure in D4Science. A visual wizard has been defined to guide Visual Media Service users to add hotspots to a 3D scene easily and quickly. This extension, initially implemented in 3DHOP will allow archaeologists to create interactive links from the digital 3D model to the related documentation without writing any source code (Task 15.2.2). Task 15.2.3 reworked the Online 3D Database System for Endangered architectural and archaeological Heritage in the south Eastern MEditerRAnea area (EpHEMERA). EpHEMERA is a service provided by the Cyprus Institute to visualize in 3D archaeological excavations, ancient buildings, and their related documentation. In EpHEMERA, it is possible to visualise, online and through standard web browsers, 3D architectural and archaeological models (classified according to a specific type of risk), query the database system and retrieve metadata attached to each digital object, and extract geometric and morphological information about the Cultural Heritage asset. The visualisation and annotation tool of the TSS project have been ported to the OpenLime library and integrated into the Visual Media Service (Task 15.2.1). An additional layer of SVG annotations have been developed and added to the service. The Annotation service have been used and improved in three different pilot projects. (Task 15.3.2) Various strands of work have been done improving services for text mining and Natural Language Processing (Task 15.4). One of these efforts has been building upon the outcomes of the preceding ARIADNE project. A set of archaeological Named Entity Recognition NLP pipelines were reconfigured and deployed for easier use on the General Architecture for Text Engineering (GATE) cloud. Another effort has been on extracting temporal archaeological information using two different parallel approaches, normalisation and named entity recognition. A Python development platform has been used to unify the various services. A Vocabulary Annotation Tool (Task 15.3.1) was developed using the same platform, as part of Task 15.4. The tool facilitates the locating and tagging of vocabulary terms within free text and outputs suggested subject annotations in a range of formats. The GeoPortal service (Task 15.5) is a new REST service designed to manage complex spatio-temporal documents defined by metadata profiles. It was released as a component of the gCube framework. A prototype using the service was deployed and operated to manage archaeological excavation projects (Task 15.7). Two services for querying the RDF AO-Cat metadata records aggregated by the ARIADNEplus Infrastructure was established (Task 15.6): a full-text index service and a SPARQL endpoint. The full- text index service is based on OpenSearch and supports the needed query functionality of the ARIADNEplus portal. The SPARQL endpoint allows performance of semantic queries on the RDF records within the ARIADNEplus data and knowledge cloud.Project(s): ARIADNEplus via OpenAIRE

ARIADNEplus D11.1 - Quantity of Access Offered - TA4
Bassett S, Potenziani M
This deliverable describes the Trans National Access (TNA) activities carried out during the ARIADNEplus project within Work Package 11 (WP11) by CNR and describes the results achieved by this work package. CNR were responsible for the delivery of TNA entitled "Visual Media for the Documentation of Fieldwork and Artefacts" at their premises in Pisa, Italy. The first TNA call went out in 2019 and only three person were able to complete their in-house training before the pandemic restrictions stopped travel. No further activities could be undertaken until 2021 when it was decided to organise the TNA as four Summer Schools and all previously accepted applicants were offered (and took up) places on the week-long courses. All candidates had to send in application forms describing their projects and how these would benefit from the use of Visual Media. One of three independent reviewers each evaluated the applications and awarded a mark and recommendation to ensure the quality and relevance of the training for the applicants. The WP11 training was designed to support researchers who wish to use visual media for the management of activities in the field and/or for the study of objects for their specific project. Participants had access to equipment and facilities in the CNR-ISTI (VCL) laboratory with technical support from the tutors, which provided the opportunity to work with state-of-the-art cameras and scanners, post-processing packages and advanced viewing platforms. Each student had the possibility to learn about creating visual media datasets for the documentation of artefacts and archaeological finds, taking in account preservation and sharing of datasets, guidance and advice were tailored to each individual project. The training concluded with a review of the results achieved and further input from local experts on continuation of the work once back home. In total, all six applicants were offered places of which five were able to attend (one dropped out due to a serious family situation). Each student was asked to complete feedback forms after completing their TNA placements. The quality of the students and their projects as well as the training provided is reflected in the feedback. All the students were highly appreciative of the Summer School and what they had learned and from the comments, it is apparent that the Summer School catered very well to the individual requirements of each student. In terms of numbers, the attendance was lower than expected (six offers for 10 places) and if the Summer School had been able to run a year or two earlier as well, it is highly likely that the target would have been met. However, it is evident that the TNA was very well received, meeting the expectations and requirements of the students so that the lower numbers actually was a benefit for those who were able to attend.Project(s): ARIADNEplus via OpenAIRE

Leafing through the painting "Ecce Homo" by Antonello da Messina: multimodal imaging techniques and data-fusion
Cucci C., Potenziani M., Albertin F., Ruberto C., Picollo M., Stefani L., Callieri M., Siotto E., Pingi P., Scopigno R., Castelli L., Taccetti F., Bettuzzi M., Brancaccio R., Morigi M. P., De Vita F.
European Research Infrastructures for Heritage Science enable access to cutting-edge technologies and top-level expertise to solve specific queries on high value artworks and heritage assets. A successful example of this approach was the ECCEHOMO Project, carried out within E-RIHS program [1-3] and dedicated to non-invasive multimodal analysis of the painting “Ecce Homo” by Antonello da Messina (ca. 1430–1479). This masterpiece of the Early Italian Renaissance is carefully preserved at the Collegio Alberoni in Piacenza (Italy). Being extremely fragile, this painting needs continuous monitoring and the implementation of careful preventive conservation strategy, which should be based on sound knowledge of materials and conservation status of the painting. The interdisciplinary research undertaken in the project combined cutting-edge 3D and 2D techniques to perform a systematic, rigorously non-invasive, analysis of the artwork. By exploiting the complementarity of imaging spectroscopic techniques operating in different regions of the electromagnetic spectrum (from X-rays to the Ultraviolet, Visible and Infrared ranges) the painting was fully investigated, virtually ‘leafing through' its levels and structures the from the surface to the wooden support. Structured-light 3D metrological survey was used to digitize the external surface of the artwork. The surface irregularities and the support were analyzed with a structured-light 3D scanner and X-ray tomography. UV fluorescence was used to visualize the aged layers of varnishes. X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI) were combined to study pictorial materials and their distributions, and the artist technique. Hidden details were brought to the light, like a fingerprints traces. Data-fusion from the 2D and 3D techniques provided new insights on the artwork and updated documentation of the conservation status. The obtained digital documentation was exploited to compile web-based interactive platforms targeted at the visualization and dissemination of the results, for both professional users and large public.

Virtual clones for cultural heritage applications
Potenziani M, Banterle F, Callieri M, Dellepiane M, Ponchio F, Scopigno R
Digital technologies are now mature for producing high quality digital replicas of Cultural Heritage (CH) artifacts. The research results produced in the last decade have shown an impressive evolution and consolidation of the technologies for acquiring high-quality digital 3D models, encompassing both geometry and color (or, better, surface reflectance properties). Some recent technologies for constructing 3D models enriched by a high-quality encoding of the color attribute will be presented. The focus of this paper is to show and discuss practical solutions, which could be deployed without requiring the installation of a specific or sophisticated acquisition lab setup. In the second part of this paper, we focus on new solutions for the interactive visualization of complex models, adequate for modern communication channels such as the web and the mobile platforms. Together with the algorithms and approaches, we show also some practical examples where high-quality 3D models have been used in CH research, restoration and conservation.

"Ecce Homo" by Antonello da Messina, from non-invasive investigations to data fusion and dissemination
Albertin F., Ruberto C., Cucci C., Callieri M., Potenziani M., Siotto E., Pingi P., Scopigno R., Bettuzzi M., Brancaccio R., Morigi M. P., Castelli L., Taccetti F., Picollo M., Stefani L., De Vita F.
Scientific investigations of artworks are crucial in terms of preservation since they provide a measurable evaluation of the materials and the state of conservation. This is the case of Antonello da Messina's painting "Ecce Homo": its delicate state of conservation, with the need for constant monitoring, required a broad and in-depth diagnostic campaign to support the restorers. The project was carried out entirely in situ using non-invasive cutting-edge techniques and proposes a multimodal and data-centric approach, integrating 3D and 2D methodologies. The surface irregularities and the support were analysed with a structured-light 3D scanner and X-ray tomography. The painting materials were investigated with X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI). Primarily, the data were jointly used for a scientific scope and provided new knowledge of the painting in terms of materials and painting techniques. In addition, two web-based interactive platforms were developed: one to provide restorers and experts with a new perspective of the hidden geometries of the painting, and the other targeted at the general public for dissemination purposes. The results of the Ecce Homo scientific analysis were exhibited, using a touch-screen interface, and developed for different user levels, from adults to kids.Source: SCIENTIFIC REPORTS, vol. 11 (issue 1), pp. 15868-15885

ARIADNEplus D15.1 - Mid-term interim report on ARIADNEplus services
Marberg Jf, Bardi A, Meghini C, Binding C, Tudhope D, Sinibaldi F, Ponchio F, Mangiacrapa F, Radmanlivaja I, Potenziani M, Lamé M, Assante M, Pagano P, Hermon S, Vassallo V
This deliverable describes the activities carried out during the first half of the ARIADNEplus project within Work Package 15 (WP15) by the different partners and describes the results achieved thus far. The work package consists of several individual tasks and subtasks with the overall goal to develop and provide useful services to archaeologists. This means that the work package in itself is by nature heterogeneous with stand-alone tasks and services. Efforts have been made to facilitate collaboration between the individual tasks through joint work package meetings. This has resulted in new cross-task contacts being made, and some sharing of expertise to improve services has been done. A service design template aligning the ARIADNEplus services with the requirements from the European Open Science Cloud (EOSC) has been created. In connection to this, the ARIADNEplus AOCAT ontology has been adapted to the requirements from the EOSC Resource Data Model. The Visual Media Service (Task 15.2.1) has had a new format added, allowing for 2D visualization of LIDAR data in DEM format. In addition, three other standards have been added: gITF, ThreeJS and IIF, supporting various functionalities in the service. The service has also been adapted to support integration with the ARIADNEplus infrastructure in D4Science. A visual wizard has been defined to guide Visual Media Service users to add hotspots to a 3D scene easily and quickly. This extension, initially implemented in 3DHOP, will allow archaeologists to create interactive links from the digital 3D model to the related documentation without writing any source code (Task 15.2.2). To integrate the EpHEMERA service (Task 15.2.3) into the ARIADNEplus infrastructure environment, a revision of the service is needed. As this revision needs to be based upon user needs and comments, tutorials have been created and a user survey has been prepared, distributed, and analysed. Revision of the service and implementation of new components have started. A prototype of an image annotation service has been created based on the OpenAnnotation format, which is intended to be integrated with the Visual Media Service. The first prototype supports vector annotation of relightable images. The GeoPortal service (Task 15.5) is a new REST service designed to manage complex space-temporal documents defined by metadata Profiles. It has been released as a component of the gCube framework. A prototype using the service has been deployed and operated to manage archaeological excavation projects (Task 15.7). Two services for querying the RDF AO-Cat metadata records aggregated by the ARIADNEplus Aggregative Infrastructure has been established (Task 15.6): a full-text index service and a SPARQL endpoint. The full-text index service is based on Elasticsearch and supports the needed query functionality of the ARIADNEplus portal. The SPARQL endpoint allows to perform semantic queries on the RDF records in the ARIADNEplus data and knowledge cloud.Project(s): ARIADNEplus via OpenAIRE

Through this White Paper, which gathers contributions from experts of 3D data as well as professionals concerned with the interoperability and sustainability of 3D research data, the PARTHENOS project aims at highlighting some of the current issues they have to face, with possible specific points according to the discipline, and potential practices and methodologies to deal with these issues. During the workshop, several tools to deal with these issues have been introduced and confronted with the participants' experiences, this White Paper now intends to go further by also integrating participants feedbacks and suggestions of potential improvements. Therefore, even if the focus is put on specific tools, the main goal is to contribute to the development of standardized good practices related to the sharing, publication, storage and long-term preservation of 3D data.Project(s): PARTHENOS via OpenAIRE

Three Armenian Manuscripts from Tuscany
Callieri M, Pingi P, Potenziani M, Ponchio F, Scopigno R
For the temporary exhibition "Three Armenian Manuscripts from Tuscany", taking palce at the Matenadaran Museum (Jerevan, Armenia) from June 9th 2019 to January 9 2020, The Visual Computing Lab of ISTI-CNR created a multimedia interactive kiosk presenting to the museum visitors the pages of the codices and the rooms of the libraries that preserved the books in their long life. The photographic campaign of the codices and buildings has also been used in the monographic volume "Three Armenian Manuscripts from Tuscany (13th - 14th century)", by Anna Rita Fantoni e Giovanna Rasario. Mandragora, Firenze. 2019. ISBN 978-88-7461-475-2 The Kiosk presents, commented by the texts edited by the experts Anna Rita Fantoni e Giovanna Rasario, high-res 360° panorama images of ther libraries (Biblioteca Medicea Laurenziana and Biblioteca di S. Matteo), high-res images of selected pages of the three codices displayed int he exhibition, and relightable RTI images of the decorated cover of one of the codices and of a parchment page illuminated in gold. The Kiosk is based on web technologies: this makes possible the installation on a stand-alone PC (like in the exhibition) but also a web publishing, linked just above. The generation of RTI, and the web visualization of RTI and multiresolution images is managed by the library Relight, developed by ISTI-CNR.
