15. Notify the repository when
changes must be made
COMPONENTS
:
•
This will provide a number of notification
services to alert repositories, which have
registered appropriately, of the probable need to
take action to ensure the preservation of their
holdings. This action could range from the need
for migration to new formats to the obsolescence
of hardware to the availability of relevant
Representation Information. In addition,
brokering services and workflow control
processes will be available to assist data holders
to access services - for example, to transform
data or to hand over holdings to longer-lived
repositories.
Activities include advising on preservation
strategies, providing support for Preservation
Planning in repositories, and sharing
Representation Information.
Without this type of background activity,
preservation is at risk by neglect. Clearly, larger
organisations may not need this, but, even in the
largest and best run organisations, individual
preservation projects may be funded on a
relatively short-term basis.
This infrastructure must itself be persistent.

information as it is ingested into an OAIS system and subsequently retrieved for use
at some time in the future. The table mentions some components which will be
introduced in later sections.
16.2 Discipline Independent Aspects
Building on the previous section we can now look as the OAIS Functional Model
(Fig.
16.2
) from another viewpoint, and try to make the distinction between the
domain dependent and domain independent parts.
The OAIS Functional Entities in the Functional Model (repeated here for conve-
nience from
Fig. 6.8
) can be used to group the domain independent concepts and
components.

The Registry/Repository concept was introduced in

Registry/Repository is used, rather than simply “Registry”, in order to stress the fact
