AB  - This paper presents a status report on some of the highlights that have taken place within the OGSADAI project since the last AHM. A description of Release 6.0 functionality and details of the forthcoming release, due in September 2005, is given. Future directions for this project are discussed. This paper also describes initial results of work being done to systematically benchmark recent OGSADAI releases. The OGSA-DAI software distribution, and more information about the project, is available from the project website at www.ogsadai.org.uk.

AB  - Data Access and Integration (DAI) of data resources, such as relational and XML databases, within a Grid context. 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/.

AB  - The UK e-Science Programme is a £250M, 5 year initiative which has funded over 100 projects. These application-led projects are under-pinned by an emerging set of core middleware services that allow the coordinated, collaborative use of distributed resources. This set of middleware services runs on top of the research network and beneath the applications we call the ‘Grid’. Grid middleware is currently in transition from pre-Web Service versions to a new version based on Web Services. Unfortunately, only a very basic set of Web Services embodied in the Web Services Interoperability proposal, WS-I, are agreed by most IT companies. IBM and others have submitted proposals for Web Services for Grids - the Web Services ResourceFramework and Web Services Notification specifications - to the OASIS organisation for standardisation. This process could take up to 12 months from March 2004 and the specifications are subject to debate and potentially significant changes.    Since several significant UK e-Science projects come to an end before the end of this process, the UK therefore needs to develop a strategy that will protect the UK’s investment in Grid middleware by informing the Open Middleware Infrastructure Institute’s (OMII) roadmap and UK middleware repository in Southampton. This paper sets out an evolutionary roadmap that will allow us to capture generic middleware components from projects in a form that will facilitate migration or interoperability with the emerging Grid Web Services standards and with on-going OGSA developments. In this paper we therefore define a set of Web Services specifications - that we call ‘WS-I+’ to reflect the fact that this is a larger set than currently accepted by WS-I – that we believe will enable us to achieve the twin goals of capturing these components and facilitating migration to future standards. We believe that the extra Web Services specifications we have included in WS-I+ are both helpful in building e-Science Grids and likely to be widely accepted.
