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. The OGSA-DAI software distribution and more details about the project are available from the project Web site at http://www.ogsadai.org.uk/.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Antonioletti, Mario</style></author><author><style face="normal" font="default" size="100%">Neil Chue Hong</style></author><author><style face="normal" font="default" size="100%">Ally Hume</style></author><author><style face="normal" font="default" size="100%">Mike Jackson</style></author><author><style face="normal" font="default" size="100%">Krause, Amy</style></author><author><style face="normal" font="default" size="100%">Jeremy Nowell</style></author><author><style face="normal" font="default" size="100%">Charaka Palansuriya</style></author><author><style face="normal" font="default" size="100%">Tom Sugden</style></author><author><style face="normal" font="default" size="100%">Martin Westhead</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Experiences of Designing and Implementing Grid Database Services in the OGSA-DAI project</style></title><secondary-title><style face="normal" font="default" size="100%">Global Grid Forum Workshop on Designing and Building Grid Services/GGF9</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2003</style></year><pub-dates><date><style  face="normal" font="default" size="100%">08/10/2003</style></date></pub-dates></dates><urls><related-urls><url><style face="normal" font="default" size="100%">http://research.nesc.ac.uk/files/Experiences%20of%20Designing%20and%20Implementing%20Grid%20Database%20Services%20in%20the%20OGSA-DAI%20Project.pdf</style></url></related-urls></urls><pub-location><style face="normal" font="default" size="100%">Chicago, USA</style></pub-location><abstract><style face="normal" font="default" size="100%">This paper describes the experiences of the OGSA-DAI team in designing and building a database access layer using the OGSI and the emerging DAIS GGF recommendations. 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.
