MUSINT II: a complex project on a virtual and interactive museum involving institutions in Florence, Rome and Heraklion ANNA MARGHERITA JASINK, CRISTIAN FARALLI, and PANAIOTIS KRUKLIDIS, University of Florence, Italy MUSINT II is part of a more general project on a series of virtual and interactive museums, using traditional and new technologies with the aim of reaching a wider audience. An interdisciplinary methodology provided by the participation of archaeologists, architects/designers and computer scientists makes the project rich in attractive solutions for visitors of different levels. MUSINT II uses a sophisticated structure, a series of 3-dimensional models produced with both photogrammetry and laser scanning. A complex database with many interconnected queries was implemented to make the study of a large number of objects more efficient and to offer truly innovative research responses with effortless data processing. New hyper-realistic techniques are used to best illustrate the reconstruction of buildings, objects and scenes of life. A specific educational section is addressed to young people, with all these new techniques applied in a winning way. The main object of MUSINT II is a specific category of small objects, sealings and seals, coming from the excavations at Haghia Triada carried out by the Italian Archaeological expedition in Crete at the beginning of 1900. Our purpose is to offer a new analytic and, at the same time, synthetic vision, addressed to a wide audience, of the historical and archaeological representation of one of the most important sites of Minoan Crete.

INTRODUCTION The development of new technologies and their application in the general field of cultural heritage has opened new perspectives also in museology [Economou 2006; Hermon and Nicolucci 2007; Oberländer-Târnoveanu 2008; EPOCH project at http://epoch-net.org/site/] to such an extent that the very idea of the museum has evolved from a traditional static form, conceived for the direct observation of artifacts to a more dynamic and interactive concept that goes beyond the single site exhibition. The individual traditional museum has been digitally duplicated to make it accessible online. Exploiting advanced digital communication tools, it is possible to go beyond the simple "replica" of the museum to show the intrinsic properties of the artifacts, hidden aspects not visible at first sight, such as the original geographical or historical location of their creation and other information accessible through dedicated databases, in some cases with recorded interviews with curators. These important advances are still confined in the domain of a static vision of the museum, although with a delocalized access; the main function of the interaction is to offer the possibility of browsing through collections and choosing which item to view. The best examples are obviously those of the British Museum and of the Louvre, with huge collections and various databases available online, educational content for children and special focus on selected items. The virtual museum [Djindjan 2007; Mancini 2008; Antoniou et al. 2016] Author's address: A. M.Jasink, University of Florence, Via San Gallo 10, Florence, Italy; email: jasink@unifi.it; C.

Kruklidis email: panaiotiskruklidis@gmail.com Permission to make digital or hardcopies of part or all of this work is granted without fee according to the open access policy of SDH. © 2017 SDH Open Access Journal can arise as an autonomous digital entity ensuring on the one hand general free access on the web and on the other hand enhancing the traditional museum experience through personalization, interactivity and richness of content. This has been accomplished by full recourse to new technologies [Stanney & Hale 2014]. It is quite evident that the virtual museum is particularly suited for applications in archaeology [Moscati 2007; Artusi et al. 2010]. New imaging methods [Remondino 2011] allow for an augmented and more significant representation of the artifacts. In addition, the virtual museum provides the audience with extended and integrated information on the site of the finds, their history and their cultural context. Finally, it allows the simultaneous exhibition of finds stored in different museums or locations, resulting in a more complete understanding of materials. To explore these and other applications for archaeology is the aim of the Virtual Museum Transnational Network VMUST (2011-2015) (http://www.v-must.net/). This paper deals with MUSINT, the first application of the virtual museum to Aegean archaeology (Bronze Age Greece). So far, this sector of studies has been variously illustrated through augmented reality techniques: see, e.g., the reconstruction of Hall 64 of the Pylos palace, Messenia (http://classics.uc.edu/prap/Hall64.html). The most important Bronze Age findings from the largest Museum collections of Greece are now available online, thanks to the Latsis Foundation Museum Cycle (http://www.latsis-foundation.org/eng/education-science-culture/culture/themuseums-cycle). However, this is simply the online transposition of actual printed catalogues, without any possibility of interaction. No Aegean site or project figures in the V-MUST Network, though various examples from classical Greece are represented. Actually, a proper virtual museum is still missing and MUSINT is the first attempt in this direction. This is why, in recent years, we developed a research project (MUSINT) on virtual and interactive museums of Aegean civilizations with the goal of reaching a wide audience, combining traditional methods and new technologies [Jasink, Tucci and Bombardieri 2011]. The virtual museum is accessible on www.aegean-museum.it or www.dbas.sciant.unifi.it website (www.aegean-museum.it/musint2/it for MUSINT II). The project includes the joint contribution of archaeologists and historians, to define the subject-matter and to write accurate texts; of architects/designers, to ensure enhanced standards of pictorial and graphic representation; and of computer scientists, to guarantee a smooth and effective connection between content and display. The intrinsic multi-disciplinary approach made the project attractive to different visitors due to the variety of available pathways. In a previous CHNT meeting, an application of MUSINT to the teaching of ancient history in primary schools was discussed [Dionisio and Jasink 2016]. In the present paper, MUSINT II, a major addition to the general project, is described. Technological methods and interactive devices have been more extensively exploited to present specific historical and archaeological topics at a high scientific level on the one hand and for a non-specialized audience on the other. MUSINT II is accessible on the websites given above. The core of the new project is the collection of small clay objects from the Neopalatial Villa of Haghia Triada, one of the main Cretan sites, which flourished in the middle of the 2nd millennium BC. This is the period of full development of the Minoan civilization. While the topic of the new project is more limited, the potential audience is definitely wider. In fact, the new museum is structured in two sections, the first addressed to scientists and curious adults and the second with explicit educational aims. The cretulae or nodules we are dealing with represent, together with the tablets, the administrative documents of the period and may bear both sealings and signs carved in Linear A script. These small objects were discovered at the beginning of the 1900s during excavations by the Italian Archaeological expedition in Crete, specifically devoted to the Phaistos and Haghia Triada sites. The majority of these finds remained in Crete, in the Heraklion Archaeological Museum, while others were taken to Italy and are presently stored in the National Archaeological Museum of Florence and in the Prehistoric-Ethnographic Pigorini Museum in Rome, the latter named after its founder Luigi Pigorini (see Fig. 1). Figure 1. Home page of MUSINT II These documents have been repeatedly analyzed since their discovery. The novelty of the present project is to make the items from the three locations simultaneously available in the single virtual Museum of MUSINT II while retaining their individuality. This is not only a useful and simplified tool for researchers but it is also a unique opportunity for other visitors to get a full idea of the Minoan administrative system. All web pages are characterized by a common graphics with rich and attractive details. The page layout is designed with a full colored background, with communicative images and animations. The color palette is decided in advance and an independent style for each page is obtained with appropriate colors. Photographs, drawings and reconstructions recall the style of the general MUSINT project and move on two parallel but different tracks, as required by appropriate approaches to scientific and educational sections. 2. HAGHIA TRIADA The Haghia Triada webpage, from which five different items can be explored, is shown in Figure 2. Fig. 2. Home page of the "Haghia Triada" website Haghia Triada History. Various phases of the archaeological site, which developed throughout the Bronze Age (Prepalatial, Protopalatial, Final/Monopalatial, Postpalatial periods), can be explored, with particular attention to the Neopalatial period, to which the sealed documents refer. Excavations. This page is concerned with Italian archaeological missions in Crete and the story of the protagonists of this adventure is also briefly described. Reading the information provided has been improved and made easier by using the so-called "popup windows" written in Javascript. This programming language is considered one of the most powerful tools for improving a website with dynamic and interactive applications. Javascript code is perfectly embedded in HTLM-PHP languages normally used to build websites. Javascript popup windows are successfully used in the MUSINT II website to open pages containing biographies with pictures and other images, without compromising the understanding of the text [Faralli 2016]. Documents. Administrative documents are described, including tablets and sealed brief inscriptions. The latter documents, in particular the Florentine and Roman pieces, are the core of MUSINT II, as will be seen in the following. They are small clay pieces with an impressed seal on one side and, often, a symbol in Linear A script on another face, as shown in Figure 3. Database. This database is one of the most innovative aspects of MUSINT II. The relational database management system used is MySQL. This system is very useful for managing dynamic websites. MySQL is fully supported by most of the programming languages, such as PHP. The interaction between the database and the web pages is achieved by using the SQL language to construct the queries and to recover the data. This architecture has been successfully used in a well-known application in the Aegean field [Arachne: http://arachne.uni-koeln.de/], which concerns the whole corpus of Minoan and Mycenaean seals. Along the same lines we have already been able to enter into an extremely more elaborate analysis of a specific sector of the seals [DBAS CHS - Cretan Hieroglyphic Seals: http://www.sagas.unifi.it/vp-394-dbas-chs-cretan-hieroglyphic-seals.html], to sort out useful statistical information. Gallery. Photos, maps and drawings complete the Haghia Triada section. Figure 3. Typologies of the administrative sealed documents from Haghia Triada (modified from HALLAGHER 1996) The present database improves considerably the study of the Haghia Triada sealed documents. First of all, it gathers in a unified digital catalogue the information on the seals and on written signs, which have been separately published in the basic volumes CMS II 6 and GORILA 2, respectively. In addition, it allows extensive and overlapping crosscorrelations that can lead to new interpretations of both seals and written signs. Dedicated files to single cretulae with a stamped seal and, very often, with carved script signs, constitute the starting point for entering into new and diversified routes by means of distinct but connected queries, which try to answer as many questions as possible. This relational database allows users to consult the information about shape, motifs, inscriptions and so on of single objects and to make queries to correlate such information; it also provides statistical data (percentages, recurrences, and so on). A more detailed discussion of the structure of this database will appear in a forthcoming paper by Alberti, Faralli and Jasink. This specific project on materials that have already been widely analyzed has been conceived not as a mere instrument but as a scientific study capable of contributing to our knowledge of the administrative system, of the figurative arts and of the daily life of the Minoan Neopalatial society, at least in Haghia Triada. 3. THE ITALIAN MUSEUMS In the present section, we consider the web pages (shown in Figure 4) of the museums in Florence and Rome that have been worked out with equal criteria but show some differences in two of the three sub-sections. A significant difference is found in the "Collections." The Roman one consists solely of materials from Crete, while the Florentine collection includes the whole Aegean world - Crete, Greece, Cyclades, Rhodes and, in addition, Cyprus - including Neolithic and Bronze Age objects as well. The Pigorini Museum of Rome received many more objects from the Italian Mission in Crete than the Florentine Museum. But in Florence, the director of the Archaeological Museum, Luigi Adriano Milani, in the years between the end of the 19th century and 1910, was in contact with various merchants and archaeological institutions, and bought or traded objects which enriched the Florentine "Aegean Collection." In Florence, therefore, materials from Haghia Triada are not as abundant as in Rome [Jasink and Bombardieri 2009; Jasink, Tucci and Bombardieri 2011; MUSINT website]. Figure 4. Web pages of the two Italian Museums with Minoan Collections This explains the difference of the third item introducing the web pages on the two Museums: "More Documents from Haghia Triada"for Rome and "Seals from Crete"for Florence. The first includes documents (three tablets and one pithos), which differ from cretulae, but still come from Haghia Triada and may be considered as administrative and written sources. The second is made up of a series of seals that came to the Florentine museum through different routes and range from the Minoan Prepalatial to the last Mycenaean period (Figure 5). These have been included in MUSINT II to complete the Italian collection of Aegean seals, theseals are presented in MUSINT II as 3D models, in the same way as the sealings. A more detailed discussion about 3D structure and the photogrammetry methodologies is dealt with in another paper in this same volume [Marziali and Dionisio 2017] and in other articles [Pitzalis et al. 2007; Sotoodeh et al. 2008]. Figure 5. Examples of seals of the Aegean collection in Florence As discussed above, the core of MUSINT II is represented by the files made available in the sub-section "Sealed documents from Haghia Triada," which has the same structure for the two museums. A dedicated file, containing a descriptive table with detailed information and, whenever possible, a 3D image, has been uploaded for each object (Figure 6). For the descriptive tables, reference can also be made to the general Haghia Triada database. Figure 6. Example of a file concerning a "hanging nodule" from Haghia Triada The 3D images, created either with photogrammetry methodologies (Florentine seals) or with laser scanning acquisition (Florentine and Roman sealings) [Remondino 2011] and uploaded on the Sketchfab platform, have been transferred in MUSINT II. To this purpose, a PRO account has been created on the Sketchfab platform in order to make a profile page available with the necessary space to implement and visualize the realized 3D models. For each 3D model, three files have been uploaded (a JPG texture file, an OBJ model file and a MTL material file) to compose a single compressed folder. This reduces the overall dimensions, thus facilitating the uploading in the website. The web pages related to the 3D models have been customized in order to obtain a better interaction between the Sketchfab service and the MUSINT II website. HTML/PHP code has been embedded to recover information from the remote archives. At the same time, a series of tailored database tables have been constructed to manage the amount of data coming from Sketchfab. Finally, SQL code has been written to allow these data to be read and shown in the website [Dionisio et al. 2016]. Tools for processing and editing of 3D meshes as MeshLab can be also found in the EPOCH project results, together with a number of documents and publications about technological strategies to improve the cultural heritage sector [McLoughlin 2007]. 4. EDUCATIONAL SECTION In the educational section (Figure 7), initially in Italian, images and contents play a basic role, with the goal of raising an immediate interest in the younger audience. Charming hand-made drawings have been created with traditional techniques and with the support of computer graphics. Six different webpages may be opened in this section. Videos, games and storytelling are proposed to the audience, in a mix that has been variously experienced by other projects [Danks et al. 2007; Ripanti 2015; Antoniou et al. 2016; McLoughlin et al. 2007; the CHESS project at http://www.chessexperience.eu/; the EMOTIVE project at http://emotiveproject.eu/]. Figure 7. Home page of the Educational section Videos. Five videos have been inserted here. The files are directly uploaded in the server where the website is running in order to avoid banners or advertising from third-party services. Despite the small amount of disc space, the videos are well balanced, with good resolution and lag-free streaming through the internet. The
