"Joint Digital University Archives - "Pilot Project" at SLU"

Aims and Objectives

One of the major aims is to document and to evaluate a possible strategy for digital preservation,  and to suggest a model for a joint digital university archives

The objectives are to:

- Use a sufficient number of different datasets/databases to get experience on digital preservation
- Test preservation in ”native format/bit preservation”/ and ”functional preservation”
- Migrate one system into another without losses of the authenticity, integrity, reliability and possibility to reuse the information
- Choose format independent from hard- and software and document the migration
- Find a proper level for metadata description
- Test Dspace as a technical solution in connection to implementation of OAIS-model

The SLU project group

The project group comprises nine scientists (all faculties represented: Faculty of Forest Sciences, Faculty of Natural Resources and Agricultural Sciences, Faculty of Veterinary Medicine and Animal Science, Faculty of Landscape Planning, Horticulture and Agricultural Science), three ICT-staff, two librarians and university archivist as a project leader

 Realization issues

- The pilot project started in May 2004 and will run until May 2005
- The project has been/is carried out by three stages
- Phase 1, May – October 2004; installation of Dspace and test of two databases:
”Longitudinal experiments on soil” from the Department on Soil Sciences and ”National Survey of Lakes and Running Waters” from the Department of Environmental Assessment
- Phase 2, November 2004– January 2005; metadata issues, migration and test of one more database: ”Hen genetics” from the Department of Animal Breeding and Genetics”
- Phase 3, February – April 2005:  completion of test with ”Longitudinal experiments”, documentation of XML-migration (extraction of database structure and content); DTD for different databases; Dspace – possibilities and limits

Course of events

- Difficulties with transfer in native format
- Shifting of focus: fewer databases than planned from the beginning; extraction of DTD/XML from a database in the middle instead
- Metadata issues:
- Mapping of required descriptive metadata (both content and context), structural and administrative metadata
- Comparison   with OAIS preservation metadata, ISAD(G) and national standard
- Dublin Core metadata elements in Dspace
-    Dspace isssues:
–   Installation, authority system
–   Description levels
–   User interface
–   Format registry
–   Metadata

Project outcomes

-  Metadata model
AIP(Archival Information Package)=CI(Content Information)+PDI(Preservation Description Information)
PDI=Provenance+Reference+Fixity+Context Info
- General DTD – preservation in XML
- Preparing of Submission Information Packages (SIP) – by XML migration and corresponding, native format if possible
- Five XML-files for database preservation
Collection of metadata from DB, completion and connection to DC metadata in Dspace, content in XML-format (schema.xml, database.dtd, data.xml, data.dtd and schema.xsl – optional)
- AIP=SIP+Dspace metadata added automatically
- Future user interface (DIP)
XSL for data and information presentation
