4 Publications issued in Germany since 1913 German-language publications issued abroad since 1913 Digital "hand-hold" publications (CD-ROM, DVD, Floppy) are covered by the current law and deposited within DDB Online publications are not covered by the current law. In the near future it will likely become a legal deposit for all networked digital publications produced in Germany and for the german Web Our task: Collecting and archiving

5 Electronic archives at Die Deutsche Bibliothek 43.000 Online-Dissertations 454 e-journals and 1.400 monographs from Springer (Heidelberg, Berlin) 80 newsletters 3.500 electronic publications from approx. 210 commercial and non-commercial publishers Web-Sites workflows, modules, procedures

8 Archiving the bit stream Digital information is stored as a bit stream on physical media Storage media types change quickly and are subject to obsolescence Storage media are unstable and can degrade quickly So we need Stability of the data-carrier Copying (refreshing) Migration of the data carrier e.g. magnetic optical Risk management And we need: Procedures to ensure the authenticity of objects

15
15 General goals of nestor create a network for information and communication about present and future LTP activities in Germany establish a cross-sectorial community to promote and support LTP activities and to raise awareness in society trigger synergies between on-going activities in Germany and cooperate with international partners and projects
16
16 National initiative II: kopal Co-operative development of a long-term digital information archive funded by the Federal Ministry for Education and Research Financial volume: 4,2 Mio + self-financed activities of all partners, duration: 1.7.2004 – 30.6.2007 Task: Development of a standardized long-term preservation solution to facilitate long-term preservation for other libraries / industries Solution as a facilitator for co-operation between libraries and other institutions / companies
17
17 kopal: Concept and background Basis: DIAS (Digital Information and Archiving System) of the Royal Dutch Library, The Hague Developed by IBM reliable (hopefully) Implementation of the OAIS standard Further development of a suitable long-term preservation component (emulation, migration) Starting point for preservation planning What weve missed: Enhancement for cooperative usage Hosting outside the library (remote access) Development of a universal object scheme A more generic approach Conclusion: Extension of DIAS-Core and development of peripheral open- source based software tools to broaden its usability
