The prototype architecture is introduced, and the pivotal role of DISPEL as a canonical language is explained. The architecture promotes the exploration and exploitation of distributed and heterogeneous data and spans the complete knowledge discovery process, from data preparation, to analysis, to evaluation and reiteration. The architecture evaluation included large-scale applications from astronomy, cosmology, hydrology, functional genetics, imaging processing and seismology.

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. The OGSA-DAI software distribution and more information about the project is available from the project website at http://www.ogsadai.org.uk/.

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.
