Abstract:
Digital preservation aims at maintaining digital objects and
data accessible over long periods of time. Data grids provide several
functionalities required by digital preservation systems, especially when
massive amounts of data must be preserved, as in e-Science domains. We
propose the use of existing data grid solutions to build frameworks for
digital preservation. In this paper we survey the main threats to digital
preservation, which are used to identify a central point of failure in the
metadata catalog of the iRODS data grid solution. We propose three
extensions to the iRODS framework, to overcome the shortcomings of
iRODS when used as a digital preservation system.
