1. 1 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. 2 focus on Using URN:NBN as persistence identifier for referencing and as identifier in an archiving workflow Workflow between a local repository and the national library archive

3. 3 Outline DiVA project and its objectives DiVA publishing system DiVA Archive and archiving workflow URN:NBN and it’s role in the workflow Conclusions and next steps

4. 4 DiVA Project Digitala 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. 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

6. 6 Author DiVA Manager Local Repository Word Processor Word Processing Format (Template) DiVA Document Format Local Long-term Storage Long-term storage packages DiVA Document Format

7. 7 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. 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. 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. 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. 11 How can we minimize risks for data loss? Multiple copies in different locations Mechanism to keep track of copies

12. 12 Analysis of interest –Authors Dissemination of their intellectual output –Universities Track research output Reduce publishing cost Increase impact –National libraries Legal deposit

13. 13 Strategies Decision to use XML as a primary storage format Decision to use URN:NBN Decision to cooperate with the Royal Library Decision to fit all needs into an automated workflow

14. 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

15. 15 Web Services Author Metadata Dissemination Services Dublin Core MARC 21 TEI Header Endnote Reference Manager URN:NBN Register Format Export Formats DiVA Document Format Local Repository Word Processor Word Processing Format (Template) Content Dissemination Services PDF DocBook TEI HTML Export Formats

16. 16 Implementation of the Archiving Workflow Assignment of the URN:NBN to the resources Implementation of URN:NBN Resolution Service URN:NBN as a unique identifier within the archive URN:NBN as a naming convention for files, directories and archival packages URN:NBN as a part of disseminated metadata

17. 17 Assignment of the URN:NBN Sub domain – managed locally Structure URN:NBN:se:X:diva URN:NBN:se:uu:diva+locally managed serial number URN:NBN is used as identifier for each item – an item is a single publication without consideration of format

18. 18 Implementation of URN:NBN Resolution Service Only basic functionally, more development planned Implemented as a java-servlet and contains an harvester which can harvest URN:URL-bindings from many different repositories

19. 19 Resolution Service Configuration File Other URN:NBN Register Format request response request response URN:NBN:se to URL mappings request e.g. http://urn.kb.se/resolve?urn= response user redirected to an URL DiVA User Royal Library Repositories URN:NBN Register Format URN:NBN resolution service

20. 20 URN:NBN as a naming convention for files, directories and archival packages

21. 21 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

22. 22 Archiving Package

23. 23 Central Local URN:NBN Resolution Service Long-term Storage Library Catalogue Long-term Storage urn:nbn:se:….urn:nbn:se:.. -> http://www… urn:nbn:se:.. -> http://www... urn:nbn:se:.. -> http://www... List of URN:NBN to URL mappings Metadata & Content Repository Long-term storage packages MARC 21XML Metadata

24. 24 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 URN:NBN 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. 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. 26 Next steps New project funded by Royal Library’s 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
