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 requirements of long term digital archives. Specifically, we have built flexible tools for implementing general ingestion workflows, active monitoring and auditing of the archive’s collections to ensure their long-term availability and integrity, storage organization and indexing to optimize access. These tools are platform and architecture independent, and have been tested using a wide variety of collections on heterogeneous computing platforms. In this paper, we will primarily focus o
