Data Curation and Preservation IG

There are four large initiatives in the EU and the UK that are investigating preservation: - CASPAR (David Giaretta) - PLANETS (Adam Farquhar, Hans Hofmann) - DPE (Seamus Ross) - Digital Curation Centre (Chris Rusbridge)

The projects are investigating representation (CASPAR) - how to characterize the structure and information content of digital documents, and management policies (PLANETS) - how to enforce preservation policies such as the number of replicas and migration to new technology. They are also constructing testbeds for the demonstration of preservation tools and services.

The related projects in the US include: - NARA Transcontinental Persistent Archive - NHPRC Persistent Archive Testbed - Library of Congress NDIIPP - Library of Congress DigArch - DSpace - Fedora

Each of these preservation projects is building upon data grid technology for the management of distributed shared collections. The goal is to differentiate between management of distributed data and application of preservation processes that generate the required archival form.

SDSC is collaborating on development of open source software with these projects based on iRODS (integrated Rule-Oriented Data System). The first release is scheduled in the next 1-2 weeks. This new technology is intended to automate the application of management policies across distributed shared collections.

The IVOA needs to specify the management policies that are required for image archives, for data products used in publications, and for the processes that generate the data products (mosaics, image cutouts, simulation output).
