1 1 Data for the Future: the German Project "Co-operative Development of a Long-term Digital Information Archive" (kopal) Hands-on Workshops Reinhard Altenhöner, Die Deutsche Bibliothek, Frankfurt am Main

2 2 Agenda The challenge: Long term preservation of our digital heritage – introduction National background / strategy: nestor & kopal The kopal initiative – our technical approach for LTP

3 3 Same procedure as every day? © KB, The Hague

4 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 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

6 6 Persistent access via Uniform Resource Name (URN) URN

8 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

9 9 Conclusion: the challenge of LTP Bit-stream Hard- and Software to read 110111011100111100110100101010111010111001010101110001101010101010001101010101010101010100010101010101010101 010101010101000101010101010101010011100000101111110011011101110011110011010010101011101011100101010111000110 101010101000110101010101010101010001010101010101010101010101010100010101010101010101001110000010111111001101 110111001111001101001010101110101110010101011100011010101010100011010101010101010101000101010101010101010101 Hard- and Software to interpret Hard- and Software to display Reading a document

14 14 nestor Network of Expertise in Long-Term Storage of Digital Resources for Germany kopal Co-operative development of a long-term digital information archive National initiatives

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
