Library Digital Repository Manager

Motivation

The National Digital Stewardship Alliance (NDSA), which is an initiative of the National Digital Information Infrastructure and Preservation Program (NDIIPP) of the Library of Congress, maintains a matrix, Levels of Digital Preservation. This covers five functional areas, storage, integrity, control, metadata, and content. The Library performs at the very highest level with respect to storage, because it relies on DLDC system administrators and that portion of the Library's operational budget which the DLDC administers for storage. The Library expects to do very well with respect to archival content, since the Digital Accessioning Specialist has been rehired after a hiatus of five years. However, the Library has not had a position for performing the remaining three functions, integrity, control, and metadata. Integrity has rarely been checked; control is practically non-existent; metadata is often minimal. This is potentially an impediment to establishing the Library's position as a trusted digital repository. It is expected that the Library Digital Repository Manager, after discussion with the Director, Digital Library Development Center, will improve the Library's performance with respect to the NDSA levels of digital preservation.
