Introduction
•Almost all aspects of
repository operation are dependent upon
the format of the objects in the repository
•Without proper characterization of digital objects
(format typing and technical
metadata), effective long-term preservation
is difficult, if not impossible
•Repositories need to ensure that:
–Digital object content streams are valid with respect to their format
–Metadata encapsulated
within object content streams are consistent
with externally supplied metadata
