Multiple projects in the US are using data grid technology to build preservation environments. The concept driving this approach is the recognition that at the point in time when new technology is being incorporated in a preservation environment, both the old and the new technology are present.

The data virtualization mechanisms provided by data grids make it possible to interact simultaneously with both versions of the technology. A preservation environment based on data grid technology inherently contains the functionality needed to manage technology evolution.

In this talk, Reagan Moore discusses the concepts used to implement data grids (data virtualization, trust virtualization, latency management, collection management, and federation management) and maps the concepts onto the principles used to manage preservation environments (authenticity, integrity, and infrastructure independence).

This event is run in collaboration with DELOS (Network of Excellence on Digital
Libraries) Digital Preservation Cluster.

About the speakers

  • Dr Reagan Moore

    San Diego Supercomputer Center

    Dr Reagan Moore is Director of Data and Knowledge Systems at the San Diego Supercomputer Center. He coordinates research efforts in development of massive data analysis systems, data grids, digital libraries, and persistent archives. Moore is the principal investigator for the development of the Storage Resource Broker data grid technology, which is used to support international shared collections. He has been at SDSC since its inception, initially being responsible for operating system development. Prior to that he worked as a computational plasma physicist at General Atomics on equilibrium and stability of toroidal fusion devices. He has a PhD in plasma physics from the University of California, San Diego, (1978) and a BS in physics from the California Institute of Technology (1967).
