•Rationale for using mdRef:
–A separate metadata file hierarchy mirrored file hierarchy of the AIHT collection; kept
down the size of the METS
document (which were
HUGE)
–Provided more granularity in cases where edits or replacement of the metadata for a single file was needed
–Allowed more efficient access mechanisms provided by the filesystem instead of the slower access methods of current generation XML tools
•
•Disadvantages to export library:
–Required much more resource to process
–More difficult to manage the correlation of metadata per file with the inventory and logical and physical structures within the METS document
