The penetration of ICT in the management and study of material culture and the emergence of digital cultural repositories and linked cultural data in particular are expected to enable new paths in humanities research and new approaches to cultural heritage. Success is contingent upon securing information trustworthiness, long-term preservation, and the ability to re-use, re-combine and re-interpret digital content. In this perspective, we review the use in the cultural heritage domain of digital curation and curation-aware repository systems; achieving semantic interoperability through ontologies; explicitly addressing contextual issues of cultural heritage and humanities information; and the services of digital research infrastructures.

Video games proved to be an attractive media for presenting cultural heritage issues. They can use virtual worlds to present cultural and historic information in amazing and highly appealing way. Each video game is implemented using set of valuable artifacts (components) reflecting technological, socioeconomic and historical issues. These software components are known as software assets, which are key output of the RAGE project. They can be used by game developers to enhance the pedagogical and educational value of their games. These software assets cover a broad spectrum of functionalities, including emotion detection, intelligent adaptation and social gamification. In order to facilitate integration and interoperability, all of these assets adhere to a common model, which describes their properties through a set of metadata. In this paper, we present the RAGE asset model and asset metadata model, highlighting key issues and challenges in constructing RAGE assets and using asset metadata model with flexible metadata editor, facilitating both adaptation and improvement of the asset metadata model.

In the light of the recent concerns in the assessment of the new conservation treatments and of the development and application of methodologies, technologies, models and tools for CH damage assessment, this paper will deal with some innovative topics related to the digital models for protecting cultural heritage assets in front of various damages. Application of new technologies and digitalization of Basarabi monument is a preventive measure, helping us to build a virtual reconstructions as model for its potential reconstruction and preserving, to give access for the widest possible audience. It will be discussed the new technologies, as the non-destructive diagnosis technologies for the safe conservation a this historic, cultural and architectural – Basarabi churches. For the micro-climatic measurements, a number of sensors have been well distributed inside and outside and a diagram of humidity an temperature is evaluated. The practical examples of restoration and preservation and innovative solutions for the consolidation of this architectural monument, in relation with digitalization (by on-site and remotely data collection, virtual reality and documentation of the heritage). For a digital image of this monument, both a 3D laser scanner and some common digital photos are used, in order to obtain the 3D model of the church, and of the envelope of the church that should be applied over it to stop the seriously damage processes.

The digitization of Cultural Heritage assumes an interdisciplinary approach, collaborative knowledge co-creation, and distant communication. This can only be fulfilled by ICT means requiring in turn alignment between those who deliver the technical (IT) support and those who are in the role users. A Service-Oriented approach is considered adequate in this regard because of users’ composing services at high level (with underlying technical complexity remaining hidden) and developers’ considering the software components whose functionality is delivered through the services. All this requires however complex regulations to conform with. Semiotic norms in combination with workflows are considered in this regard. In this paper, we propose an approach based on Service-Oriented Computing and Organizational Semiotics, directed to Cultural Heritage digitization. The approach is partially illustrated by means of an example.

The digital recording of Cultural Heritage (CH) and its metadata relates to the concept for data warehousing systems and their lifecycle. It uses models and development tools of ETL packages. The tasks used to extract metadata from raw digitized CH data often include hard computing problems, including NP-complete problems. This paper describes the current state of digital preservation of Cultural Heritage with an accent on data integration and performance optimization of processes. We show our vision for further solutions for automated optimization of resource utilization in ETL jobs cutting development cost. In parallel, we describe our experiment that uses quantum computation (in simulation mode) to solve hard combinatorial problems as multiple query optimization.

The reported evaluation of the problematic encountered by non-contact characterization of natural dyestuffs demonstrates that practically no one analytical method alone – destructive, less, or non – can warrant absolute reliability of the results. The main obstacles are due, in general, to our limited knowledge on reactivity of natural compounds, their sources, methods of proceeding and application; to the complexing role of the ambient/medium on the photo reactions, as well as to the actual possibilities of analytical techniques; to the lack of commonly accepted standards amongst different scientific traditions, etc. For to overwhelm these drawbacks and optimize accuracy of NDs characterization, we propose the integration of chemio-physical with computational assessment. The proposed approach consists in calculation the probability of a hypothesis comparing new results with already stored interdisciplinary data using the high performance ensemble techniques Random Forest and Random Subspace based on the genetic approach termed EV-Ensemble approach. Its role is to render more accurate the analytical results, to avoid sampling and simplify the identification analysis, to facilitate interdisciplinary applications of NDs in high technologies, and to share generated experience between the research community.

Dementia will soon be ranked as the world’s largest economy. At present, it ranges from the 16th to 18th place, with countries such as Indonesia, the Netherlands, and Turkey. Dementia is not only a financial challenge, but also a philosophical one. It provokes a paradigm shift in the traditional view of healthcare and expands the classic concepts of human personhood and autonomy. A promising response to these challenges is the idea of cooperative solidarity. Cooperative solidarity, contrary to its ‘humanitarian’ version, promotes spontaneous teamwork and individual initiative. It obliges us not only to help 'the suffering, the troubled and the disadvantaged’, but above all to support those who already do so for spontaneous moral or affective reasons. In the field of dementia study, solidary initiatives are described within the framework of supportive care.

While websites are of great interest for digital archives, the digital long term preservation of websites is a huge problem. The reason is that websites consist of a large number of file formats and require today’s hardware and software environment to work properly. PABLO is a software tool that processes websites and transforms them into a dramatically simplified form that is simple enough for digital archiving and exhaustive enough to preserve the websites content and appearance and allows users to browse the entire site like the original.
