14:30 Principles and Architecture
Malcolm Atkinson
This session discusses the challenges that scientists are facing
today in the integration of structured data. It will build on
earlier sessions on data management and illustrate the architectural
strategies for accommodating diversity and moving selection and
derivation computations closer to the data. The technical challenge
is to do this safely for a wide range of applications.
15:15 OGSA-DAI as an Example
Amy Krause, Tom Sugden
OGSA-DAI is a grid middleware that allows different data resources
to be accessed as web services. In this session, we will give
an overview of the features and the architecture of OGSA-DAI.
We will present some real use-cases and scenarios to show how
the software is being used in the field.
15:40 OGSA-DAI in detail
Tom Sugden, Amy Krause
This session presents a more detailed view of OGSA-DAI components.
The OGSA-DAI framework is highly extensible and can be tailored
to address an individual application’s requirements. Those
extensibility points and how they can be exploited will be discussed.
Components such as the client toolkit which are going to be used
in the following session are introduced.

Rangoon and Lancaster; and for two companies: Sun Microsystems
(at SunLabs in California) and O2 (an Object-Oriented DB company
in its early years in Versailles). He led the development of
the Department of Computing Science in Glasgow and is now Professor
of e-Science in the School of Informatics, University of Edinburgh.
He has more than 130 publications. He has taken leading roles
in national strategic research and infrastructure committees.
