requirements of the designated community/communities influencing the
selection of the services to be provided.
If the designated community/communities or its/their requirements change
over time, the DR should respond by adapting its services.
Possible designated communities include:
• Employees of an official body, a research institute etc.
• Scientists working in a particular discipline
• The general public
2 The digital repository grants its designated community/communities
adequate access to the information represented by the digital objects.
The DR should regard its primary task as the current and future use of the
information represented by the digital objects on the part of its designated
community. Use of the digital objects is predicated on their preservation,
their accessibility and on ensuring the ability to interpret them. Use may be
adequate despite being restricted due to legal reasons (c.f. 3.3.) or not all
properties of the original being preserved (c.f. 9.2.).
So-called "dark archives" are set up with no possibility for their use at
present; they will only be used if the primary archive is rendered nonfunctional
for whatever reason. In the event of such a crisis, use must
then be guaranteed.
2.1 The digital repository ensures its designated community/ communities can
access the digital objects.
The DR should ensure that authorised users have access to the digital
objects. This includes appropriate search possibilities. When determining its
service portfolio, the DR takes the needs of its designated
community/communities into account. The DR announces in advance its
conditions of use and any costs which may arise, listing these in a
transparent manner.
Access can be obtained by:
• Accessing the digital objects
• Creating or supplying an analogue copy (e.g., as print-out by the user
or in the form of a print-on-demand service)
• Creating or supplying a digital copy (e.g. download to a storage
medium by the user, email delivery)
• Creating interfaces to permit access via other systems to the digital
objects.
2.2 The digital repository ensures that the designated community/communities
can interpret the digital objects.
