A1 - Antonioletti, M. A1 - Alemu, T. Y. A1 - Atkinson, M. A1 - Jackson, M. A1 - Theocharopoulos, E. AB - OGSA-DAI (Open Grid Services Architecture Data Access and Integration) is a framework for building distributed data access and integration systems. Until recently, it lacked the built-in functionality that would allow easy creation of federations of distributed data sources. The latest release of the OGSA-DAI framework introduced the OGSA-DAI DQP (Distributed Query Processing) resource. The new resource encapsulates a distributed query processor, that is able to orchestrate distributed data sources when answering declarative user queries. The query processor has many extensibility points, making it easy to customize. We have also introduced a new OGSA-DAI Views resource that provides a flexible method for defining views over relational data. The interoperability of the two new resources, together with the flexibility of the OGSA-DAI framework, allows the building of highly customized data integration solutions.

AB - There is a rapidly growing wealth of data [1]. The number of sources of data is increasing, while, at the same time, the diversity, complexity and scale of these data resources are also increasing dramatically. This cornucopia of data o ers much potential; a combinatorial explosion of opportunities for knowledge discovery, improved decisions and better policies. Today, most of these opportunities are not realised because composing data from multiple sources and extracting information is too dicult. Every business, organisation and government faces problems that can only be addressed successfully if we improve our techniques for exploiting the data we gather.

A1 - Perrott, P. A1 - Procter. R. A1 - Rusbridge, C. AB - More data will be produced in the next five years than in the entire history of human kind, a digital deluge that marks the beginning of the Century of Information. Through a year‐long consultation with UK researchers, a coherent strategy has been developed, which will nurture Century‐of‐Information Research (CIR); it crystallises the ideas developed by the e‐Science Directors’ Forum Strategy Working Group. This paper is an abridged version of their latest report which can be found at: http://wikis.nesc.ac.uk/escienvoy/Century_of_Information_Research_Strategy which also records the consultation process and the affiliations of the authors. This document is derived from a paper presented at the Oxford e‐Research Conference 2008 and takes into account suggestions made in the ensuing panel discussion. The goals of the CIR Strategy are to facilitate the growth of UK research and innovation that is data and computationally intensive and to develop a new culture of ‘digital‐systems judgement’ that will equip research communities, businesses, government and society as a whole, with the skills essential to compete and prosper in the Century of Information. The CIR Strategy identifies a national requirement for a balanced programme of coordination, research, infrastructure, translational investment and education to empower UK researchers, industry, government and society. The Strategy is designed to deliver an environment which meets the needs of UK researchers so that they can respond agilely to challenges, can create knowledge and skills, and can lead new kinds of research. It is a call to action for those engaged in research, those providing data and computational facilities, those governing research and those shaping education policies. The ultimate aim is to help researchers strengthen the international competitiveness of the UK research base and increase its contribution to the economy. The objectives of the Strategy are to better enable UK researchers across all disciplines to contribute world‐leading fundamental research; to accelerate the translation of research into practice; and to develop improved capabilities, facilities and context for research and innovation. It envisages a culture that is better able to grasp the opportunities provided by the growing wealth of digital information. Computing has, of course, already become a fundamental tool in all research disciplines. The UK e‐Science programme (2001–06)—since emulated internationally—pioneered the invention and use of new research methods, and a new wave of innovations in digital‐information technologies which have enabled them. The Strategy argues that the UK must now harness and leverage its own, plus the now global, investment in digital‐information technology in order to spread the benefits as widely as possible in research, education, industry and government. Implementing the Strategy would deliver the computational infrastructure and its benefits as envisaged in the Science & Innovation Investment Framework 2004–2014 (July 2004), and in the reports developing those proposals. To achieve this, the Strategy proposes the following actions: 1. support the continuous innovation of digital‐information research methods; 2. provide easily used, pervasive and sustained e‐Infrastructure for all research; 3. enlarge the productive research community which exploits the new methods efficiently; 4. generate capacity, propagate knowledge and develop skills via new curricula; and 5. develop coordination mechanisms to improve the opportunities for interdisciplinary research and to make digital‐infrastructure provision more cost effective. To gain the best value for money strategic coordination is required across a broad spectrum of stakeholders. A coherent strategy is essential in order to establish and sustain the UK as an international leader of well‐curated national data assets and computational infrastructure, which is expertly used to shape policy, support decisions, empower researchers and to roll out the results to the wider benefit of society. The value of data as a foundation for wellbeing and a sustainable society must be appreciated; national resources must be more wisely directed to the collection, curation, discovery, widening access, analysis and exploitation of these data. Every researcher must be able to draw on skills, tools and computational resources to develop insights, test hypotheses and translate inventions into productive use, or to extract knowledge in support of governmental decision making. This foundation plus the skills developed will launch significant advances in research, in business, in professional practice and in government with many consequent benefits for UK citizens. The Strategy presented here addresses these complex and interlocking requirements. VL - 27 ER - TY - JOUR T1 - Distributed Computing Education, Part 1: A Special Case?

A1 - Cassidy, K. A1 - Fergusson, D. A1 - Atkinson, M. A1 - Vander Meer, E. A1 - McGeever, M. AB - The International Summer Schools in Grid Computing (ISSGC) have provided numerous international students with the opportunity to learn grid systems, as detailed in part 2 of this series (http://doi.ieeecomputersociety.org/10.1109/MDSO.2008.20). The International Winter School on Grid Computing 2008 (IWSGC 08) followed the successful summer schools, opening up the ISSGC experience to a wider range of students because of its online format. The previous summer schools made it clear that many students found the registration and travel costs and the time requirements prohibitive. The EU FP6 ICEAGE project held the first winter school from 6 February to 12 March 2008. The winter school repurposed summer school materials and added resources such as the ICEAGE digital library and summer-school-tested t-Infrastructures such as GILDA (Grid INFN Laboratory for Dissemination Activities). The winter schools shared the goals of the summer school, which emphasized disseminating grid knowledge. The students act as multipliers, spreading the skills and knowledge they acquired at the winter school to their colleagues to build strong and enthusiastic local grid communities.

AB - In the first article of this series (see http://doi.ieeecomputersociety.org/10.1109/MDSO.2008.16), we identified the need for teaching environments that provide infrastructure to support education and training in distributed computing. Training infrastructure, or t-infrastructure, is analogous to the teaching laboratory in biology and is a vital tool for educators and students. In practice, t-infrastructure includes the computing equipment, digital communications, software, data, and support staff necessary to teach a course. The International Summer Schools in Grid Computing (ISSGC) series and the first International Winter School on Grid Computing (IWSGC 08) used the Grid INFN Laboratory of Dissemination Activities (GILDA) infrastructure so students could gain hands-on experience with middleware. Here, we describe GILDA, related summer and winter school experiences, multimiddleware integration, t-infrastructure, and academic courses, concluding with an analysis and recommendations.

A1 - Vander Meer, E. A1 - Fergusson, D. A1 - Artacho, M. AB - The development of e-Infrastructure, of which grid computing is a fundamental element, will have major economic and social benefits. Online and financial businesses already successfully use grid computing technologies, for instance. There are already demonstrations showing the benefits to engineering, medicine and the creative industries as well. New research methods and technologies generate large data sets that need to be shared in order to ensure continued social and scientific research and innovation. e-Infrastructure provides an environment for coping with these large data sets and for sharing data across regions. An investment in educating people in this technology, then, is an investment that will strengthen our economies and societies. In order to deliver e-Infrastructure education and training successfully in the EU, we must develop a policy framework that will ensure shared responsibility and equivalent training in the field. This document focuses primarily on the current state of grid and e-Science education, introducing key challenges and the opportunities available to educational planners that serve as a starting point for further work. It then proposes strategies and policies to provide a supportive framework for e-Infrastructure education and training. The ETTF Report concludes with policy recommendations to be taken forward by the e-IRG. These recommendations address issues such as the level of Member State investment in e-Infrastructure education, the harmonisation of education in distributed-computation thinking and in the use of e-Infrastructure and the development of standards for student and teacher identification, for the sharing of t-Infrastructure (and training material) and for accreditation.

Finally, we will describe how the project relates to other ongoing community engagement efforts in the UK and worldwide. Introduction Existing investments in e-Science and Grid computing technologies have helped to develop the capacity to build e-Infrastructures for research: distributed, networked, interoperable computing and data resources that are available to underpin a wide range of research activities in all research disciplines. In the UK, the Research Councils and the JISC are funding programmes to support the development of essential components of such infrastructures such as National Grid Service (www.ngs.ac.uk) or the UK Access Management Federation (www.ukfederation.org.uk) as well as discipline-specific efforts to build consistent and accessible instantiations of e-Infrastructures, for example the e- Infrastructure for the Social Sciences (Daw et al. 2007). These investments are complemented by an active programme of community engagement (Voss et al. 2007). As part of the community engagement strand of its e-Infrastructure programme, JISC has funded the e-Uptake project, a collaboration between the ESRC National Centre for e-Social Science at the University of Manchester, the Arts & Humanities e-Science Support Centre at King's College London and the National e-Science Centre at the University of Edinburgh. In this paper we present the project's activities to date to widen the uptake of e-Infrastructure services by eliciting information about the barriers to and enablers of uptake, developing adequate interventions such as training and outreach events, running workshops and the deploying a UK 'one-stop-shop' for support and event information as well as training material.

AB - The grid provides a vision in which resources, including storage and data, can be shared across organisational boundaries. The original emphasis of grid computing lay in the sharing of computational resources but technological and scientific advances have led to an ongoing data explosion in many fields. However, data is stored in many different storage systems and data formats, with different schema, access rights, metadata attributes, and ontologies all of which are obstacles to the access, integration and management of this information. In this chapter we examine some of the ways in which these differences can be addressed by grid technology to enable the meaningful sharing of data. In particular, we present an overview of the OGSA-DAI (Open Grid Service Architecture - Data Access and Integration) software, which provides a uniform, extensible framework for accessing structured and semi-structured data and provide some examples of its use in other projects. The open-source OGSA-DAI software is freely available from http://www.ogsadai.org.uk.

In this paper we will review existing work on studies of infrastructure and community development, requirements elicitation for existing services as well as work within the arts and humanities and the social sciences to establish e-Research in these communities. We then describe two projects recently funded by JISC to study barriers to adoption and responses to them as well as use cases and service usage models.

AB - Analyses of disasters such as the Piper Alpha explosion (Sylvester-Evans and Drysdale, 1998), the World Trade Centre collapse (Torero et al, 2002, Usmani et al, 2003) and the fires at Kings Cross (Drysdale et al, 1992) and the Mont Blanc tunnel (Rapport Commun, 1999) have revealed many mistaken decisions, such as that which sent 300 fire-fighters to their deaths in the World Trade Centre. Many of these mistakes have been attributed to a lack of information about the conditions within the fire and the imminent consequences of the event. E-Science offers an opportunity to significantly improve the intervention in fire emergencies. The FireGrid Consortium is working on a mixture of research projects to make this vision a reality. This paper describes the research challenges and our plans for solving them.

AB - The UK e-Science programme has initiated significant developments that allow networked grid technology to be used to form virtual colaboratories. The e-Science vision of a globally connected community has broader application than science with the same fundamental technologies being used to support eCommerce and e-Government. The broadest vision of e-Science outlines a challenging research agenda for the computing community. New theories and models will be needed to provide a sound foundation for the tools used to specify, design, analyse and prove the properties of future grid technologies and applications. Fundamental research is needed in order to build a future e-Science infrastructure and to understand how to exploit the infrastructure to best effect. A future infrastructure needs to be dynamic, universally available and promote trust. Realising this infrastructure will need new theories, methods and techniques to be developed and deployed. Although often not directly visible these fundamental infrastructure advances will provide the foundation for future scientific advancement, wealth generation and governance. • We need to move from the current data focus to a semantic grid with facilities for the generation, support and traceability of knowledge. • We need to make the infrastructure more available and more trusted by developing trusted ubiquitous systems. • We need to reduce the cost of development by enabling the rapid customised assembly of services. • We need to reduce the cost and complexity of managing the infrastructure by realising autonomic computing systems.

AB - This is the first collection of papers from GRUMPS [http://grumps.dcs.gla.ac.uk]. The project only started up in February 2001, and this collection (frozen at 1 Sept 2001) shows that it got off to a productive start. Versions of some of these papers have been submitted to conferences and workshops: the website will have more information on publication status and history. GRUMPS decided to begin with a first study, partly to help the team coalesce. This involved installing two pieces of software in a first year computing science lab: one (the "UAR") to record a large volume of student actions at a low level with a view to mining them later, another (the "LSS") directly designed to assist tutor-student interaction. Some of the papers derive from that, although more are planned. Results from this first study can be found on the website. The project also has a link to UWA in Perth, Western Australia, where related software has already been developed and used as described in one of the papers. Another project strand concerns using handsets in lecture theatres to support interactivity there, as two other papers describe. As yet unrepresented in this collection, GRUMPS will also be entering the bioinformatics application area. The GRUMPS project operates on several levels. It is based in the field of Distributed Information Management (DIM), expecting to cover both mobile and static nodes, synchronous and detached clients, high and low volume data sources. The specific focus of the project (see the original proposal on the web site) is to address records of computational activity (where any such pre-existing usage might have extra record collection installed) and data experimentation, where the questions to be asked of the data emerge concurrently with data collection which will therefore be dynamically modifiable: a requirement that further pushes on the space of DIM. The level above concerns building and making usable tools for asking questions of the data, or rather of the activities that generate the data. Above that again is the application domain level: what the original computational activities serve, education and bioinformatics being two identified cases. The GRUMPS team is therefore multidisciplinary, from DIM architecture researchers to educational evaluators. The mix of papers reflects this.

ED - Klaus Dittrich ED - Giovanna Guerrini ED - Isabella Merlo ED - Marta Oliva ED - M. Elena Rodriguez AB - Large scale and long-lived application systems, enterprise applications, require persistence, that is provision of storage for many of their data structures. The JavaTM programming language is a typical example of a strongly-typed, object-oriented programming language that is becoming popular for building enterprise applications. It therefore needs persistence. The present options for obtaining this persistence are reviewed. We conclude that the Orthogonal Persistence Hypothesis, OPH, is still persuasive. It states that the universal and automated provision of longevity or brevity for all data will significantly enhance developer productivity and improve applications. This position paper reports on the PJama project with particular reference to its test of the OPH. We review why orthogonal persistence has not been taken up widely, and why the OPH is still incompletely tested. This leads to a more general challenge of how to conduct experiments which reveal large-scale and long-term effects and some thoughts on how that challenge might be addressed by the software research community.
