16.2.4.1 Access Control/DRM/Trust
Access Control, Trust and Digital Rights Management must attempt to withstand
changes in:
•
individuals, and their roles and even their existence
•
organisations
•
legal systems, including new rights, new types of events and new obligations
•
security systems such as certificates and passwords
A digital object may be deposited in an archive with one particular system of Access
controls and DRM, but may (in fact certainly will) be used under a completely
different access control system.
While DRM systems could be made specific to domains, the requirement for
survivability to change will tend to require a significant independence from
domain considerations.
16.2.4.2 Finding Aids Based on PDI
A Finding Aid is defined in OAIS as
a software program or document that allows
Consumers to search for and identify Archival Information Packages of interest.
If the Consumer does not know a priori what specific holdings of the
OAIS are of interest, the Consumer will establish a Search Session with the
OAIS. During this Search Session the Consumer will use the OAIS Finding
Aids that operate on Descriptive Information, or in some cases on the AIPs
themselves, to identify and investigate potential holdings of interest. This may
be accomplished by the submission of queries and the return of result sets to
the Consumer.
OAIS provides terminology for the information which is used by the Finding
Aids, for example
Descriptive Information, Associated Descriptions and
Collection Descriptions.
However further specification of this information is not
provided by OAIS, in part because of the great variety of types of information which
could be involved.
A type of Finding Aid which could have some discipline independent aspects
is based on standardised PDI components, and in particular discipline indepen-
dent aspects of Provenance.
