Abstract
Modern scientific experiments can generate large
amounts of data, which may be replicated and
distributed across multiple resources to improve
application performance and fault tolerance. Whilst a
number of different replica management systems exist,
particular communities usually adopt a single system.
This creates problems when an application program
spans more than one community, because it may need
to target more than one middleware layer. One
solution to this problem is to build a more flexible data
access layer above the specific replica middleware. In
this paper, we discuss such an architecture, the Grid
