Chronopolis: Federated Digital Preservation Across Space and Time
||This diagram illustrates the
multiple facets of the proposed Chronopolis project. Activities span
production adminstration and policy, R&D, and a Digital Library
Facility. This is underpinned by a collection of technologies and
services required to deliver a digital preservation system.
There is a critical and growing need to organize, preserve, and
make accessible the increasing number of digital holdings that
represent vital intellectual capital, much of which is precious
and irreplaceable. Chronopolis is a strategic collaboration among the
San Diego Supercomputing Center (SDSC), NCAR/CISL, the University
of California Library System, and the University of Maryland, and
it is aimed at developing national-scale digital preservation
infrastructure that has the potential to serve the broad science
and engineering community. This new effort encompasses studying
viable models and effective systems that facilitate establishing
standard reference datasets, preserving collections that evolve
over time, and establishing preservation resources "of last resort"
for digital assets that might become lost. Digital collections that
must persist for 100 or more years are one important focus of this
activity. A special synthesis of relationships and capabilities
are required to approach this problem: scientists, librarians,
curators, computer scientists, and long-term cyberinfrastructure.
The problem spans the gamut of academic scientific disciplines,
historical collections, and digital library content.
During FY 2006, we made substantial progress on the
plans outlined in CISL's
FY 2005 Annual Report. CISL contributed to the formation of the Chronopolis
Consortium and continued to develop relationships and explore funding
pathways, including joining in a Letter of Intent to The National Digital
Information Infrastructure and Preservation Program (NDIIPP). We
executed a Memo of Understanding with SDSC that provides a mechanism
and resources to begin the process of geographic replication of
critical datasets at each other's sites, an initial step in the
direction of a more comprehensive preservation infrastructure. In
support of this work, we integrated some of the core Chronopolis
software infrastructure on our computational systems. CISL staff
also contributed to an NSF-funded workshop on Chronopolis
infrastructure and a workshop on New Collaborative Relationships
for Digital Data, jointly sponsored by the National Science
Foundation and the Association of Research Libraries.
In FY 2007, we will deploy additional core Chronopolis
infrastructure on our computational systems and on the TeraGrid,
integrating and testing end-to-end capabilities that include
archival functions on the NCAR MSS. We will place several unique
datasets into the preservation environment for geographic
replication, with an emphasis on unique atmospheric and solar
observations. We expect to continue our activities in pursuit
of additional support for this important project, along with
a continued focus on advocacy and outreach.
CISL is engaging in Chronopolis as an important strategic
thrust, supporting it through a combination of NSF Core funding
and NCAR's Cyberinfrastructure Strategic Initiative.
