TY - JOUR T1 - Embedded systems for global e-Social Science: Moving computation rather than data JF - Future Generation Computer Systems Y1 - 2013 A1 - Ashley D. Lloyd A1 - Terence M. Sloan A1 - Antonioletti, Mario A1 - Gary McGilvary AB - There is a wealth of digital data currently being gathered by commercial and private concerns that could supplement academic research. To unlock this data it is important to gain the trust of the companies that hold the data as well as showing them how they may benefit from this research. Part of this trust is gained through established reputation and the other through the technology used to safeguard the data. This paper discusses how different technology frameworks have been applied to safeguard the data and facilitate collaborative work between commercial concerns and academic institutions. The paper focuses on the distinctive requirements of e-Social Science: access to large-scale data on behaviour in society in environments that impose confidentiality constraints on access. These constraints arise from both privacy concerns and the commercial sensitivities of that data. In particular, the paper draws on the experiences of building an intercontinental Grid–INWA–from its first operation connecting Australia and Scotland to its subsequent extension to China across the Trans-Eurasia Information Network–the first large-scale research and education network for the Asia-Pacific region. This allowed commercial data to be analysed by experts that were geographically distributed across the globe. It also provided an entry point for a major Chinese commercial organization to approve use of a Grid solution in a new collaboration provided the centre of gravity of the data is retained within the jurisdiction of the data owner. We describe why, despite this approval, an embedded solution was eventually adopted. We find that ‘data sovereignty’ dominates any decision on whether and how to participate in e-Social Science collaborations and how this might impact on a Cloud based solution to this type of collaboration.

Project members also participate in the development of DAI standards through the GGF DAIS WG. The standards that emerge through this effort will be adopted by OGSA-DAI once they have stabilised. The OGSA-DAI developers are also engaging with a growing user community to gather their data and functionality requirements. Several large projects are already using OGSA-DAI to provide their DAI capabilities. This paper presents a status report on OGSA-DAI activities since the last AHM and announces future directions.

A1 - Dave Pearson A1 - To AB - The OGSA-DAI project has been producing Grid-enabled middleware for almost two years now, providing data access and integration capabilities to data resources, such as databases, within an OGSA context. In these two years, OGSA-DAI has been tracking rapidly evolving standards, managing changes in software dependencies, contributing to the standardisation process and liasing with a growing user community together with their associated data requirements. This process has imparted important lessons and raised a number of issues that need to be addressed if a middleware product is to be widely adopted. This paper examines the experiences of OGSA-DAI in implementing proposed standards, the likely impact that the still-evolving standards landscape will have on future implementations and how these affect uptake of the software. The paper also examines the gathering of requirements from and engagement with the Grid community, the difficulties of defining a process for the management and publishing of metadata, and whether relevant standards can be implemented in an efficient manner.

This middleware is designed for enabling other UK e-Science projects that require database access and providing the basic primitives for higher-level services such as Distributed Query Processing. OGSA-DAI also intends to produce one of the required reference implementations of the DAIS specification once this becomes a proposed recommendation and, until then, scope out their ideas, provide feedback as well as directly contributing to the GGF working group. This paper enumerates the issues that have arisen in tracking the DAIS and OGSI specifications whilst developing a software distribution using the Grid services model; trying to serve the needs of the various target communities; and using the Globus Toolkit OGSI core distribution.
