archivists?
I thought about your question a bit more, and we actually had a discussion about this last
week as we
just hired a new digital archivist at CHM.
Archivists would prefer to have the contents of the tape, not the image itself, since that
would
be of the most use to researchers in the future. Ideally, what would be saved is a picture
of the
container where all of the markings are visible, the image, a description of the image
format, and
the decoded and verfied contents of the image, along with SHA1 or better checksums for
fixity checking

Is the description and code for the current version of bagit, developed by the California
Digital Library,
Stanford, and the Library of Congress as a transfer standard.
