This work intends to provide a data management solution based on the concepts of dataspaces for the large-scale and long-term management of scientific data. Our approach is to semantically enrich the existing relationship among primary and derived data items, and to preserve both relationships and data together within a dataspace to be reused by owners and others. To enable reuse, data must be well preserved. Preservation of scientific data can best be established if the full life cycle of data is addressed. This is challenged by the e-Science life cycle ontology, whose major goal is to trace the semantics about procedures in scientific experiments. We present a theoretical dataspace model for e-Science applications, its implementation within a dataspace support platform and an experimental evaluation on top of two real world application domains.

At the end of September 2009, a new Italian GPS receiver for radio occultation was launched from the Satish Dhawan Space Center (Sriharikota, India) on the Indian Remote Sensing OCEANSAT-2 satellite. The Italian Space Agency has established a set of Italian universities and research centers to implement the overall processing radio occultation chain. After a brief description of the adopted algorithms, which can be used to characterize the temperature, pressure and humidity, the contribution will focus on a method for automatic processing these data, based on the use of a distributed architecture. This paper aims at being a possible application of grid computing for scientific research.

The Distributed Research Infrastructure for Hydro-Meteorological Study (DRIHMS) is a co-ordinated action co-funded by the European Commission. DRIHMS analyzes the main issues that arise when designing and setting up a pan-European Grid-based e-Infrastructure for research activities in the hydrologic and meteorological fields. The main outcome of the project is represented first by a set of Grid usage patterns to support innovative hydro-meteorological research activities, and second by the implications that such patterns define for a dedicated Grid infrastructure and the respective Grid architecture.

Rozproszona infrastruktura naukowa przeznaczona do badań hydrometeorologicznych (Distributed Research Infrastructure for Hydro-Meteorological Study - DRIHMS) stanowi element skoordynowanej akcji współfinansowanej przez Komisję Europejską. Celem DRIHMS jest analiza głównych problemów spotykanych w dziedzinie hydrologii i meteorologii. Głównym wynikiem projektu będzie zestaw wzorców użytkowania środowisk gridowych w celu wspomagania nowoczesnych badań hydrometeorologicznych oraz wnioski wynikające z powyższego zastosowania, mogące mieć wpływ na dalszy rozwój dedykowanych rozwiązań gridowych.

The growing number of resources available to researchers in the e-Science domain has opened new possibilities for constructing complex scientific applications while at the same time introducing new requirements for tools which assist developers in creating such applications. This paper discusses the problems of rapid application development, the use of distributed resources and a uniform approach to resource registration, discovery and access. It presents the Grid Resource Registry, which delivers an abstract layer for computational resources. The Registry is a central place where developers may search for available services and from which the execution engine receives technical specifications of services. The Registry is used throughout the lifetime ofthe e-science application, starting with application design, through implementation to execution.

Rosnąca liczba zasobów dostępnych dla naukowca z jednej strony otworzyła nowe możliwości w konstruowaniu złożonych aplikacji naukowych, a z drugiej przyniosła dodatkowe wymagania dla narzędzi wspierających proces tworzenia oraz uruchamiania takich aplikacji. W artykule przedstawiono wyzwania związane z szybkim wytwarzaniem aplikacji naukowych, które wykorzystują rozproszone zasoby oraz związane z nimi trudności wynikające z rejestrowania, wyszukiwania i wywoływania zasobów używanych przez aplikację. Rozważania przedstawiono na przykładzie Grid Resource Registry - centralnego rejestru, który dostarcza abstrakcyjnego opisu rozproszonych zasobów, dzięki czemu w znaczący sposób proces wytwarzania oraz uruchamiania aplikacji naukowych może zostać uproszczony.

Enabling Technologies and Design Values for Building the Real World Web

The notions of ubiquitous computing and networking, and the increasing availability of compact, low power sensing technologies naturally lead to the idea that we can expect to see large numbers of sensors embedded in the fabric of our everyday lives and that these could form a “Real World Web” of real-time data sources about our world. Implications for e-Research include sharing of real-time data from scientific instruments and aggregation of many types of information to answer complex questions as they arise. The World Wide Web was made possible through a combination of the increasing availability of the Internet, simple network protocols, and open content and delivery standards. The Real World Web can only grow and become self-sustaining if we pay attention to these same core design values of simplicity and openness. Recent developments in cloud computing and in Web 2.0 technologies and design stances provide enablers from which to build the Real World Web, but in addition, require a shift in thinking away from a classical Web services and layered standards model. This paper explores these issues and the role of the Real World Web as a paradigm for sharing instruments, sensors and other real-time data sources in e-Research collaborations.

The digital gap prevents today in many parts of the world the diffusion of e-Science which is considered as one of the key enablers of progress and development in the 21st Century. On the other hand, investing in e-Infrastructures is the key for a long-term growth and changes in the Society in developing Countries. The paper discusses this topic and provides some details about the EUMEDGRID Project experience in the Mediterranean area.
