Query: Principles for Digital Preservation   The immense investments in creating and disseminating digitally represented
information have not been accompanied by commensurate effort to ensure the
longevity of information of permanent interest. Asserted difficulties with
long-term digital preservation prove to be largely underestimation of what
technology can provide. We show how to clarify prominent misunderstandings and
sketch a 'Trustworthy Digital Object (TDO)' method that solves all the
published technical challenges.
