This Service Genre describes
systems that support the long-term preservation, management and managed
disposal, if appropriate, of digital materials. The goal of such a
system is to allow retrieval of the materials by members of a
designated community of potential users. Long term preservation
requires active decisions to be made about ways of ensuring that
technological changes, such as new media and data formats and
obsolescence of old ones, do not prevent retrieval in future. Long term
planning to prevent degradation of the storage medium is also required.
In
order to achieve this long term preservation, the digital materials are
typically supplemented by a variety of metadata, including explicit
preservation metadata, to form an information object. Access to the
system will typically be via Search or Harvest (described as Service
Genres elsewhere in the e-Framework).
