ABSTRACT1 The preservation of digital entities requires data management technologies that are provided by digital libraries and data grids. Digital libraries provide standard data organization and presentation mechanisms. Data grids provide support for infrastructure independence, the ability to incorporate new technology as it becomes available. Preservation environments integrate these technologies to assure the authenticity and integrity of digital entities. We will describe the concepts behind preservation and illustrate the concepts with three data preservation environments based on the NARA research prototype persistent archive, the NHPRC Persistent Archive Testbed, and the NSF NSDL persistent archive.

1. INTRODUCTION Preservation environments ensure the authenticity and integrity of records for time periods much longer than the lifetime of any individual software or hardware technology. Authenticity is the assertion that the provenance context that describes the creator, creating institution, and creation procedures remain associated with the record. Integrity is the assertion that the bits comprising the record have not been corrupted. The management of technology evolution is an assertion that an infrastructure independent architecture can be created that allows the incorporation of new technologies, formatting standards, and presentation technologies.
