The increasing integration of 3D technologies and machine learning is fundamentally reshaping mineral sciences and cultural heritage, establishing the foundation for an emerging “Mineralogy 4.0” framework. However, public engagement with digital 3D collections is often limited by complex or costly interfaces, such as VR/AR systems and traditional touchscreen kiosks, creating a clear need for more intuitive, accessible, and more engaging and inclusive solutions. This paper presents PETRA, an open-source, gesture-controlled system for exploring 3D rocks and minerals. Developed in the TouchDesigner environment, PETRA utilizes a standard webcam and the MediaPipe framework to translate natural hand movements into real-time manipulation of digital specimens, requiring no specialized hardware. The system provides a customizable, node-based framework for creating touchless, interactive exhibits. Successfully evaluated during a “Long Night of Museums” public event with 550 visitors, direct qualitative observations confirmed high user engagement, rapid instruction-free learnability across diverse age groups, and robust system stability in a continuous-use setting. As a practical case study, PETRA demonstrates that low-cost, webcam-based gesture control is a viable solution for creating accessible and immersive learning experiences. This work offers a significant contribution to the fields of digital mineralogy, human–machine interaction, and cultural heritage by providing a hygienic, scalable, and socially engaging method for interacting with geological collections. This research confirms that as digital archives grow, the development of human-centered interfaces is paramount in unlocking their full scientific and educational potential. Full article

In her 2022 video installation, Blast Furnace No. 2, artist Su Yu Hsin explores the history of the German factory, Henrichshütte Ironworks. Namely, the artist focuses on Henrichshütte’s former blast furnace, which was bought by a Chinese steel mill in September 1989 and moved to China, where it operated until 2015. Now a state-owned museum, this former factory, located in Hattingen, Germany, is a snapshot of the past—a memorial of sorts for the region’s bygone industrial prosperity. The history and intercontinental movement of this blast furnace inspires Su’s affinities towards spaces located in-between shifting temporalities, identities, and changing environmental conditions within Hattingen and beyond. Su weaves archival materials, documentary film, and interview excerpts into a speculative narrative that connects the years 1989, 2022, and 2050. Blurring reality and imagination, the video follows the fictionalized trail of Lin, a Chinese translator who accompanied the dismantling of the blast furnace over thirty years ago. According to the narrative, Lin left behind an unfinished science fiction novel, which takes place in 2022. In Lin’s novel, the protagonist develops a utopian machine in the form of a blast furnace. With this apparatus, she sends herself into space with the goal of finding an alternative energy source to replace coal. Blast Furnace No. 2 constellates temporal spaces of socio-political and environmental nostalgia, predicated upon both remembered and imagined understandings of the past, present, and future. The work emphasizes contradictory gaps in between socially driven ideological systems and their afterlives, determined to memorialize what most would just as soon forget. Full article

World Heritage tourism in China regulates conservation approaches employed across natural and built heritage sites. However, focusing on the revenue-generating potential of these sites sustains material authenticity and technical conservation methods. The outcome is a conflict between conservation and commercialization, where socio-cultural values are overshadowed by the process of museumization. Underpinned by critical heritage theory and a focus on intangible heritage, this research seeks to confront this conflict by examining the shifting conservation practice at the Humble Administrator’s Garden (HAG), a World Heritage Site and Classical Garden of Suzhou, China. A mixed-methodological approach explores the interplay between architecture and landscape within its heritage conservation process, utilizing archival research, semi-structured interviews with HAG Management, and visitor journals. The study shows how HAG’s heritage is shaped by visitors’ personal experiences and emotions alongside expert interpretations, resulting in the foregrounding of diverse narratives that contribute to a holistic sense of place. Within its politicized system, the safeguarding of intangible heritage requires constant negotiation among the municipality, the market, and emerging narrators. Attempts to reinterpret its former heritage buildings demonstrate a changing conservation discourse as the site transitions from an exclusive literati estate to a multivocal space of cultural encounter. The study illustrates how a focus on narrative representation unifies architecture and landscape, reimagining centuries of literati culture. This makes conceptual space for considering how conservation management can inform a more holistic narration of ‘place’ at similar World Heritage sites via the foregrounding of previously silent stakeholders.

This essay introduces and examines the impact of the Second Sophistic in the Near East on the history of rhetoric. Although the overall impact of sophists is apparent as early as the Classical Period of ancient Greece, this work emphasizes the renaissance of sophistic rhetoric during the so-called Second Sophistic, a movement that flourished slightly before and throughout the Roman Empire. The Second Sophistic provided an educational system that proved to be a major force spreading the study and performance of rhetoric throughout the Roman Empire. This essay examines and synthesizes scholarship that employs conventional historical approaches, particularly research that often focuses on individual sophists, in order to establish a grounding (and justification) for concentrating on what is termed here as a “site-perspective.” That is, this essay stresses the importance of the sites of sophistic education and performance, arguing for such an orientation for future research. This essay also advances observations from the author’s own experiences and research at ancient sites in Greece and Turkey, as well as other sources of archaeological and epigraphical research. Such work reveals that artifacts at archaeological sites—epigraphy, statuary now held at museums in Greece and Turkey, and a range of other forms of material rhetoric—provide contextual insights into the nature, influence, and longevity of rhetoric during the Second Sophistic beyond examining the achievements of individual sophists. A site-perspective approach reveals that a symbiotic relationship existed between the educational achievements of the Second Sophistic—in which rhetoric played a major role—and the social and cultural complexities of the Roman Empire. Such observations also reveal the benefits, but also the need, for further fieldwork, archival research, and the development of new methodological procedures to provide a more refined understanding of the impact of the Second Sophistic on the history of rhetoric.

Website loading speed time matters when it comes to users’ engagement and conversion rate optimization. The websites of libraries, archives, and museums (LAMs) are not an exception to this assumption. In this research paper, we propose a methodological assessment schema to evaluate the LAMs webpages’ speed performance for a greater usability and navigability. The proposed methodology is composed of three different stages. First, the retrieval of the LAMs webpages’ speed data is taking place. A sample of 121 cases of LAMs worldwide has been collected using the PageSpeed Insights tool of Google for their mobile and desktop performance. In the second stage, a statistical reliability and validity analysis takes place to propose a speed performance measurement system whose metrics express an internal cohesion and consistency. One step further, in the third stage, several predictive regression models are developed to discover which of the involved metrics impact mostly the total speed score of mobile or desktop versions of the examined webpages. The proposed methodology and the study’s results could be helpful for LAMs administrators to set a data-driven framework of prioritization regarding the rectifications that need to be implemented for the optimized loading speed time of the webpages.

This study proposes a new museum archiving system that uses artificial intelligence (AI) technology. It suggests a new retrieval interface to extract emotional characteristics of the design work to enrich the archiving database. A virtual curation was organized to showcase the proposed archiving system. We focused on finding emotional signals with advanced technology because humans build trust and connect with each other through emotional cues. There are numerous characteristics of a single work of art, but we focused on the emotions that viewers can feel when they appreciate the art and share a connection with the artists who made the work. The research was focused on design works, and the metadata were designed to extract three dominant colors and match them with emotional adjectives to enrich the data on the paintings. The purpose of this study was to provide information for new techniques of color utilization that encapsulate emotional adjectives. Through this research, we developed an image retrieval system based on metadata and transformed intangible emotions of design work into data. With the emotion archiving system, we organized virtual curation, adding a Korean design history collection with emotional words. Full article

The monitoring and control of thermo-hygrometric indoor conditions is necessary for an adequate preservation of cultural heritage. The European standard EN 15757:2010 specifies a procedure for determining if seasonal patterns of relative humidity (RH) and temperature are adequate for the long-term preservation of hygroscopic materials on display at museums, archives, libraries or heritage buildings. This procedure is based on the characterization of the seasonal patterns and the calculation of certain control limits, so that it is possible to assess whether certain changes in the microclimate can be harmful for the preventive conservation of artworks, which would lead to the implementation of corrective actions. In order to discuss the application of this standard, 27 autonomous data-loggers were located in different points at the Archaeological Museum of l’Almoina (Valencia). The HVAC system (heating, ventilation and air conditioning) at the museum tries to reach certain homogeneous environment, which becomes a challenge because parts of the ruins are covered by a skylight that produces a greenhouse effect in summer, resulting in severe thermo-hygrometric gradients. Based on the analysis of temperatures recorded during 16 months, the air conditions in this museum are discussed according to the standard EN 15757:2010, and some corrective measures are proposed to improve the conservation conditions. Although this standard is basically intended for data recorded from a single sensor, an alternative approach proposed in this work is to find zones inside the museum with a homogeneous microclimate and to discuss next the average values collected in each area. A methodology is presented to optimize the application of this standard in places with a complex microclimate like this case, when multiple sensors are located at different positions. Full article

While digitalization of cultural organizations is in full swing and growth, it is common knowledge that websites can be used as a beacon to expand the awareness and consideration of their services on the Web. Nevertheless, recent research results indicate the managerial difficulties in deploying strategies for expanding the discoverability, visibility, and accessibility of these websites. In this paper, a three-stage data-driven Search Engine Optimization schema is proposed to assess the performance of Libraries, Archives, and Museums websites (LAMs), thus helping administrators expand their discoverability, visibility, and accessibility within the Web realm. To do so, the authors examine the performance of 341 related websites from all over the world based on three different factors, Content Curation, Speed, and Security. In the first stage, a statistically reliable and consistent assessment schema for evaluating the SEO performance of LAMs websites through the integration of more than 30 variables is presented. Subsequently, the second stage involves a descriptive data summarization for initial performance estimations of the examined websites in each factor is taking place. In the third stage, predictive regression models are developed to understand and compare the SEO performance of three different Content Management Systems, namely the Drupal, WordPress, and custom approaches, that LAMs websites have adopted. The results of this study constitute a solid stepping-stone both for practitioners and researchers to adopt and improve such methods that focus on end-users and boost organizational structures and culture that relied on data-driven approaches for expanding the visibility of LAMs services.

In recent years, the use of three-dimensional (3D) measurement and printing technologies has become an effective means of analyzing and reproducing both physical and natural objects, regardless of size. However, in some complex environments, such as coastal environments, it is difficult to obtain the required data by conventional measurement methods. In this paper, we describe our efforts to archive and digitally reproduce a giant coastal rock formation known as Sanouiwa, a famous site off the coast of Miyako City, Iwate Prefecture, Japan. We used two different 3D measurement techniques. The first involved taking pictures using a drone-mounted camera, and the second involved the use of global navigation satellite system data. The point cloud data generated from the high-resolution camera images were integrated using 3D shape reconstruction software, and 3D digital models were created for use in tourism promotion and environmental protection awareness initiatives. Finally, we fabricated the 3D digital models of the rocks with 3D printers for use as museum exhibitions, school curriculum materials, and related applications. Full article

The debate over whether we are entering the Anthropocene Epoch focuses on the unequal consumption of the Earth system’s resources at the expense of nature’s regenerative abilities. To find a new point of balance with nature, it is useful to look back in time to understand how the so-called “Great Acceleration”—the surge in the consumption of the planet’s resources—hastened the arrival of the Anthropocene. Some particular places—for various reasons—survived the Great Acceleration and, as time capsules, have preserved more or less intact some landscape features that have disappeared elsewhere. How can we enhance these living archives that have come down to us? Through the analysis of the case study of the Valley of the Temples in Agrigento (Sicily, Italy), the article presents several initiatives that have tried to answer this question. For example, the pre-Anthropocene landscape of the Valley of the Temples has preserved rare specimens of some plant species from which living gene banks have been built for the propagation of species, such as the Living Museum of the Almond Tree. In addition, the Kolymbethra, an ancient example of a Mediterranean garden, has been brought back to life revealing finds related to Greek and Arab cultivation and irrigation systems. The research perspectives opened by the “disappeared landscapes” show that the knowledge of the historical landscape, in particular the mechanisms behind its resilience, is indispensable for countering the unsustainable voracity of the Anthropocene and rediscover a renewed synergy between humankind and nature.

Memory institutions must be able to grow a fully-functional repository incrementally as collections grow, without expensive enterprise storage, massive data migrations, and the performance limits that stem from the vertical storage strategies. The Digital Repository at Scale that Invites Computation (DRAS-TIC) Fedora research project, funded by a two-year National Digital Platform grant from the Institute for Museum and Library Services (IMLS), is producing open-source software, tested cluster configurations, documentation, and best-practice guides that enable institutions to manage linked data repositories with petabyte-scale collections reliably. DRAS-TIC is a research initiative at the University of Maryland (UMD). The first DRAS-TIC repository system, named Indigo, was developed in 2015 and 2016 through a collaboration between U.K.-based storage company, Archive Analytics Ltd., and the UMD iSchool Digital Curation Innovation Center (DCIC), through funding from an NSF DIBBs (Data Infrastructure Building Blocks) grant (NCSA “Brown Dog”). DRAS-TIC Indigo leverages industry standard distributed database technology, in the form of Apache Cassandra, to provide open-ended scaling of repository storage without performance degradation. With the DRAS-TIC Fedora initiative, we make use of the Trellis Linked Data Platform (LDP), developed by Aaron Coburn at Amherst College, to add the LDP API over similar Apache Cassandra storage. This paper will explain our partner use cases, explore the system components, and showcase our performance-oriented approach, with the most emphasis given to performance measures available through the analytical dashboard on our testbed website.

In 2015, the Museum of Technology received a donation of ninety data communication devices from the 1960s to 2010s, collected and arranged by employees of the Nokia Data Communications department. The museum has been organizing (2018–2019) documentation workshops to collect information and connect individual objects with larger concepts such as company history, innovations, and technologies. The idea is to gain comprehensive contextual information about the collection by bringing together expertise and experiences of (former) Nokia employees, and documentation and interpretation skills of museum professionals. The method of the documentation workshops is a conversational interview inspired by the objects. Subsequently, workshop discussions were planned to be digested and used in cataloguing individual objects and object groups by museum professionals. Eventually significance assessment was chosen as a tool for summarizing the documentation project. The paper discusses the planning and organizing of the outcomes of the documentation workshops and asks the following questions: What is the optimal relationship between cataloguing information in the collections management system and documentation of workshop discussions preserved in the museum’s collection archive? How should the workshop be documented to trace the provenance of the information? What information should and can be collected on the workshop participants? Full article
