A Grid-Enabled Digital Library System for Natural Disaster Metadata

Abstract. The need to organize and publish metadata about European research results in the field of natural disasters has been met with the help of two innovative technologies: the Open Grid Service Architecture (OGSA) and the Resource Description Framework (RDF). OGSA provides a common platform for sharing distributed metadata securely. RDF facilitates the creation and exchange of metadata. In this paper, we present the design and implementation of a Grid-based digital library for natural-disaster research metadata. We describe the EU-MEDIN RDF schema that we propose to standardize the description of natural-disaster resources, and the gDisDL Grid service-based architecture for storing and querying of RDF metadata in a secure and distributed manner. Finally, we describe a prototype implementation of gDisDL using the Jena RDF Library by HP and the Globus 3 toolkit

MusA: Using Indoor Positioning and Navigation to Enhance Cultural Experiences in a museum

In recent years there has been a growing interest into the use of multimedia mobile guides in museum environments. Mobile devices have the capabilities to detect the user context and to provide pieces of information suitable to help visitors discovering and following the logical and emotional connections that develop during the visit. In this scenario, location based services (LBS) currently represent an asset, and the choice of the technology to determine users' position, combined with the definition of methods that can effectively convey information, become key issues in the design process. In this work, we present MusA (Museum Assistant), a general framework for the development of multimedia interactive guides for mobile devices. Its main feature is a vision-based indoor positioning system that allows the provision of several LBS, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits according to visitors' personal interest and curiosity. Starting from the thorough description of the system architecture, the article presents the implementation of two mobile guides, developed to respectively address adults and children, and discusses the evaluation of the user experience and the visitors' appreciation of these application

A new generation of cyberinfrastructure and data services for earth system science education and research

International audienceA revolution is underway in the role played by cyberinfrastructure and modern data services in the conduct of research and education. We live in an era of an unprecedented data volume from diverse sources, multidisciplinary analysis and synthesis, and active, learner-centered education emphasis. Complex environmental problems such as global change and water cycle transcend disciplinary and geographic boundaries, and their solution requires integrated earth system science approaches. Contemporary education strategies recommend adopting an Earth system science approach for teaching the geosciences, employing pedagogical techniques such as enquiry-based learning. The resulting transformation in geoscience education and research creates new opportunities for advancement and poses many challenges. The success of the scientific enterprise depends heavily on the availability of a state-of-the-art, robust, and flexible cyberinfrastructure, and on the timely access to quality data, products, and tools to process, manage, analyze, integrate, publish, and visualize those data. Concomittantly, rapid advances in computing, communication, and information technologies have revolutionized the provision and use of data, tools and services. The profound consequences of Moore's Law and the explosive growth of the Internet are well known. On the other hand, how other technological trends have shaped the development of data services is less well understood. For example, the advent of digital libraries, web services, open standards and protocols have been important factors in shaping a new generation of cyberinfrastructure for solving key scientific and educational problems. This paper presents a broad overview of these issues, along with a survey of key information technology trends, and discuses how those trends are enabling new approaches to applying data services for solving geoscientific problems

Sustainable Paths for Data-Intensive Research Communities at the University of Melbourne: A Report for the Australian Partnership for Sustainable Repositories

This report presents the local project findings with a view to identifying how these findings may add to the knowledge base for informing an e-research strategy for the University of Melbourne. It also provides important considerations for how major Government initiatives in research policy and funding might impact on research data and records management requirements. Eleven research communities from diverse disciplines were consulted for an audit of their data management practices. Researchers from these communities represent a number of diverse disciplines: Applied Economics; Astrophysics; Computer Science and Software Engineering; Education; Ethnography; Experimental Particle Physics; Humanities informatics; Hydrology and Environmental Engineering; Linguistics; Medical informatics; Neuroscience and the Performing Arts. In addition to the specific findings for each group audited, the project findings also provide information about sustainability issues around research data management practices at the university
