KOPAL - Co-operative Development of a Long-Term Digital Information Archive


The objective of KOPAL was the practical testing and implementation of a co-operatively created and operated long-term archive system for digital information. As network partners, the German National Library, the Niedersächsische Staats- und Universitätsbibliothek Göttingen (SUB) and IBM Germany implemented a co-operatively operated solution, capable of subsequent re-use by others, for the long-term preservation of digital resources. The technical operation of the system is taken care of by the Gesellschaft für Wissenschaftliche Datenverarbeitung mbH Göttingen (GWDG).

The participation of the German National Library as the national archive library and the Niedersächsische Staats- und Universitätsbibliothek Göttingen (SUB) as an innovative university information centre guaranteed that complementary viewpoints and differing user interests were taken into account in the realisation of the project. The technical realisation of the functions KOPAL is based on prior work accomplished since 2000 in a joint development project of the Koninklijke Bibliotheek (KB) and IBM. IBM has undertaken its further development toward a co-operatively maintained system equipped with standardised interfaces within the framework of KOPAL. The ingest & retrieval software produced by the network partners (koLibRI) has the status of Open Source software. Comprehensive and heterogeneous data have been fed into the system during the term of the project in order to prove the concept's capacity and usefulness. Since mid-2007, the archival system has been transferred into the productive use by the German National Library.
