Title : Interfacing the Storage Resource Broker and the GIGGLE framework

Authors : Tim Barrass, Owen Maroney, Simon Metson, David Newbold

Abstract : 
Distributed data transfer is currently characterized by the use of
widely disparate tools, meaning that significant human effort is
required to maintain the distributed system. In order to realise the
possibilities represented by Grid infrastructure, the reality of a
heterogenous computing environment must be tackled by providing means by
which these disparate elements can communicate.

Two such data distribution tools are the SRB and the EU DataGrid's Data
Management fabric, both widely used by many large scientific projects.
Both provide similar functionality- the replication and cataloguing of
datasets in a globally distributed environment. Significant quantities
of data are currently stored in both. Moving data from the SRB to the
EUDG, however, requires significant intervention and is therefore not
scalable.

This paper presents a mechanism by which the SRB can automatically
interact with the GIGGLE framework (as implemented by the EUDG) allowing
access to SRB data using Grid tools.
