Implementing a Reliable Digital Object Archive

چکیده
An Archival Repository reliably stores digital objects for long periods of time (decades or centuries). The archival nature of the system requires new techniques for storing, indexing, and replicating digital objects. In this paper we discuss the specialized indexing needs of a write-once archive. We also present a reliability algorithm for effectively replicating sets of related objects. We describe an administrative user interface and a data import utility for archival repositories. Finally, we discuss and evaluate a prototype repository we have built, the Stanford Archival Vault, SAV.

Tools and Services for Long-Term Preservation of Digital Archives
We have been working on a technology model to support the preservation and reliable access of long term digital archives. The model is built around a layered object architecture involving modular, extensible components that can gracefully adapt to the evolving technology, standards, and protocols. This has led to the development of methodologies, tools and services to handle a number of core re...
متن کاملA Standards-based Solution for the Accurate Transfer of Digital Assets
This article describes results of a collaboration between the Research Library of the Los Alamos National Laboratory (LANL) and the American Physical Society (APS) aimed at designing and implementing a robust solution for the recurrent transfer of digital assets from the APS collection to LANL. In this solution, various recent standards are combined to obtain an asset transfer framework that sh...
متن کاملThe Stanford Archival Vault: A reliable, long-term data archive
Information stored and managed in an archive today can be lost within years or decades if special care is not taken. The causes include media and system failures and format obsolescence. At Stanford we have implemented a prototype archival repository, the Stanford Archival Vault (SAV, pronounced \save"), for the long term preservation of digital objects. These objects may include documents, the...
متن کاملQualitative Evaluation of Digital Hand X-rays is Not a Reliable Method to Assess Bone Mineral Density
Object: The gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (DEXA). Prior studies have shown poor reliability using analog wrist X-rays in diagnosing osteoporosis. Our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand X-rays in osteoporosis screening. We hypothesized that similar to analog counterparts, dig...
متن کاملImplementing the FuGE Object Model: a Systems Biology Data Portal and Integrator
The Centre for Integrated Systems Biology of Ageing and Nutrition has developed a Data Portal and Integrator (CISBAN DPI) that is based on the FuGE Object Model and which archives, stores, and retrieves raw high-throughput data. Until now, few published systems have successfully integrated multiple omics data types and information about experiments in a single database. The CISBAN DPI is the fi...
