Archiving Workflow between a Local Repository and the National Library Archive

Archiving Workflow between a Local Repository
and the National Library Archive

• Experiences from the DiVA Project
• Eva Müller, Peter Hansson, Uwe Klosa, Stefan
  Andersson
• Electronic Publishing Centre
• Uppsala University Library, Sweden

2
focus on

• Using URNNBN as persistence identifier for
  referencing and as identifier in an archiving
  workflow
• Workflow between a local repository and the
  national library archive

3
Outline

• DiVA project and its objectives
• DiVA publishing system
• DiVA Archive and archiving workflow
• URNNBN and its role in the workflow
• Conclusions and next steps

DiVA ProjectDigitala Vetenskapliga Arkivet
(Digital Scientific Archive)

• Since September 2000
• Objectives
• Technical solutions well functioning workflow
  supporting full-text publication of doctoral
  theses, working papers
• Explore ways to ensure the future use and
  understanding of the digital objects in the
  archive

5
DiVA Publishing System

• Focus on workflow
• reuse and enhance the data directly from the
  source document,originally created by authors,
  for metadata and a digital master for an
  electronic printed version
• store checksum the files
• assign a persistent identifier
• send a copy to the National Library Archive

Implementation

• Java XML technologies
• Currently an Oracle database used for indexing
  and searching
• Architecture component-based design
• Modularity and reusability of the components
• Possibility to seamlessly replaced modules with
  improved implementations of the component

8
DiVA system

• Used by 5 universities in Sweden
• Stockholm, Umeå, Uppsala och Örebro university
  Södertörns högskola
• Soon 1 university in Denmark
• Århus University (Staatsbibliotek i Århus)

9
Issues

• How can we ensure the future access and
  understanding of documents we produce locally?
• What factors increase potential for success?
• Can these factors be integrated into an automated
  and low-cost workflow?

10
How can we ensure accessibility in the future?

• A stable point of reference (persistent
  identifier)
• Use human-readable, non-proprietary storage
  format
• Storage in several locations

11
How can we minimize risks for data loss?

• Multiple copies in different locations
• Mechanism to keep track of copies

12
Analysis of interest

• Authors
• Dissemination of their intellectual output
• Universities
• Track research output
• Reduce publishing cost
• Increase impact
• National libraries
• Legal deposit

13
Strategies

• Decision to use XML as a primary storage format
• Decision to use URNNBN
• Decision to cooperate with the Royal Library
• Decision to fit all needs into an automated
  workflow

14
DiVA Document Format

• Internal format
• Version 1.0 (described in XML Schema)
• 99 elements
• Component based
• Extensible
• Administrative elements are combined with
  descriptive elements
• DocBook DTD is used for the content part of the
  document

Implementation of the Archiving Workflow

• Assignment of the URNNBN to the resources
• Implementation of URNNBN Resolution Service
• URNNBN as a unique identifier within the archive
• URNNBN as a naming convention for files,
  directories and archival packages
• URNNBN as a part of disseminated metadata

17
Assignment of the URNNBN

• Sub domain managed locally
• Structure URNNBNseXdiva
• URNNBNseuudivalocally managed serial number
• URNNBN is used as identifier for each item an
  item is a single publication without
  consideration of format

18
Implementation of URNNBN Resolution Service

• Only basic functionally, more development planned
• Implemented as a java-servlet and contains an
  harvester which can harvest URNURL-bindings from
  many different repositories

Workflow to the National Library Archive

• Archiving packages
• Administrative and descriptive metadata stored in
  XML
• Today content in pdf and where possible even in
  XML
• Each manifestation is bundled to AP
• General data
• Format specific data

Conclusions

• Low-cost system that supports a fully automated
  workflow from the point of submission works well
• Using harvesting model for updates to the mapping
  registry makes the management of URNNBN simple
• Automatic creation of MARC21 records makes
  cataloguing faster and less expensive
• Push model to deliver archival packages makes
  this process more reliable and easier to manage

25

• Use of XML for all metadata associated with each
  archival package increases the likelihood of
  future understanding of the digital objects in
  the archive and offers the potential to easily
  extract document metadata, if necessary
• Modularity of technical solution offers advantage
  of component reusability and is a solid basis for
  further local and cooperative development
• Long-term access to institutional research
  publications can be assured with cooperation from
  national libraries

26
Next steps

• New project funded by Royal Librarys Department
  for National Co-ordination and Development
  (BIBSAM)
• Examine and evaluate current solutions
• Develop and implement a generalized archiving
  workflow between a local repository and a
  national archive focusing on the variety of
  publishing platforms and systems
