The German National Library (DNB)
– Task: collecting, permanently archiving, bibliographically
classifying and making available to the general public…
… all German and German-language publications from 1913,
… foreign publications about Germany,
… translations of German works,
… and the works of German-speaking emigrants published
abroad between 1933 and 1945.

Long term preservation at the DNB
– Since 1998: Voluntary deposit of e-theses
– Since 2006: Legal mandate for online publications
– Since 2003: nestor, network of expertise in digital preservation
– 2004-2007: kopal project
-
Development of a co-operative long-term preservation system
– 2009-2012: DFG project DP4lib
-
Developement of a long-term archiving service
-
Re-design of DNB‘s ingest workflow
– In parallel: Development of the digital publication collection
and ingest workflow, EU projects, policy development, …

Long term preservation and trust
– Digital preservation requires co-operative solutions
– Distribution of labor and co-operation require trust
– Since 2003: nestor Catalogue of Criteria for Trusted
Digital Repositories (today: DIN 31644)
– Since 2009: Collaboration between nestor and DSA
– 2010: European MoU to set up an integrated framework
for auditing and certifying digital repositories

Motivation for seeking external
assessment (DNB)
– Systematic review of status quo
– Have our processes and documentation reviewed,
scrutinized, and ideally approved by external
professionals
– Determination of strengths and gaps
– Transparency towards the preservation community

DNB and the DSA
– DSA = entry level of evaluating digital archives
– Research data are not the main focus of DNB
– DNB’s policies are designed for (legal deposit)
publications, and do not necessarily address data
specific aspects
!
– The DSA criteria were found to be generic enough for an
assessment

The assessment process
– Assessment „owner“ collected the required
documentation and references
– Review and discussion in team
– Approval by senior management

Iterative process
Example: Metadata
DSA Guideline
Assessment
3. The data producer provides the research data together with the metadata
requested by the data repository
****
Main issues:
DNB has defined a core set of metadata elements, which all content providers have to provide
together with their publications. The core set covers monographs, university dissertations and
journals. Currently, the metadata are accepted in ONIX or XMetaDissPlus. Formal validation is
carried out after submission.

Example: Responsibility
DSA Guideline
Assessment
9. The data repository assumes responsibility from the data producers for
access and availability of the digital objects
****
Main issues:
DNB collects publications according to its legal mandate and is obliged by law (DNBG) to preserve
these publications (access and availability) for the future. The DNB does that on its own
responsibility, in fulfilling its legal mandate. The deliverer is obliged by law, not by contract to deliver
the deposit copy.

Example: Integrity
DSA Guideline
Assessment
11. The data repository ensures the integrity of the digital objects and the
metadata
****
Main issues:
DNB uses checksums on archival package level (each package consisting of digital objects plus
metadata) to control the integrity of its archival holdings. From a more general perspective, the
Bitstream Preservation Policy is designed to ensure data integrity.

Example: Authenticity
DSA Guideline
Assessment
12. The data repository ensures the authenticity of the digital objects and the metadata
****
Main issues:
Because any depositor must register, DNB knows where and whom it receives its data from. So we can be
relatively sure that we are not “spammed”. Provenance is recorded in the metadata and stored together with
the delivered document. DNB has also implemented access protection measures.
To prove the authenticity of stored documents, DNB uses checksums. The checksum is saved as a file along
with the original document and displayed to the user on a front page before he accesses the file. The user can
then derive the code himself and can compare it to the code assigned to the “original”.
Moreover, the mandatory URN for each publication stored in the DNB repository supports assurance of
authenticity. By default, each new version of a publication is assigned a new URN, so that the user can be
sure that a URN always resolves to the original publication.
Metadata provided by submission are permanently linked and preserved with the object.

Example: Access
DSA Guideline
Assessment
14. The data consumer complies with access regulations set by the data
repository
****
Main issues:
By law, DNB has the mandate to provide access to its holdings. Deliverers can only define the
access level (a) minimal standard: in-house access on dedicated reading places, b) registered users
via internet, c) unlimited access). Basically anyone aged 18 can register for a library card at DNB.
With registration, users recognize DNB’s terms of use. According to the terms of use, e.g., copies
must be in accordance with copyright law. To make sure this rule is adhered DNB provides copyright
protected digital works at dedicated supervised reading places only.

Expectations fulfilled…
– Reminder of motivation:
- Systematic review of status quo
- Have our processes and documentation reviewed, scrutinized, and
ideally approved by external professionals
- Determination of strengths and gaps
- Transparency towards the preservation community

??

| DSA Case Study (DNB) | 8th October 2013
Strengths and gaps
– Most criteria were basically implemented
– Documentation was occasionally fragmentary or too
unspecific
– Follow up:
- Design and publication of long term preservation policy
- Thorough documentation of workflows and practices
16 | 17
| DSA Case Study (DNB) | 8th October 2013
Further benefits
– Assessment excercise and policy follow up raised the
profile of long term preservation within the organisation
(higher management)
– DSA as a solid basis for assessment against DIN31644
– Renewal of DSA will hopefully document progress made
