Digital longterm preservation[edit]
- Methods
- Emulation: Reproduction of the original hardware, software and operating system
- Migration: Periodical transfer of the digital material from one (older) hard/software configuration to another (newer) one
- OAIS Model
- Presentation of the OAIS Model (Reference Model for an Open Archival Information System), which is a terminological and structural concept for the digital longterm preservation
- Presentation of the Nestor "Kriterienkatalog vertrauenswürdige digitale Langzeitarchive"
- Data formats and standards, amongst others the characteristics of picture formats
- Raster graphics consists of pixels
- compressed, e.g. TIFF uncompressed
- uncompressed, e.g. TIFF group 4 (lossless), GPEG and GIV (lossy)
- Vector graphics describe pictures through geometric forms like lines, circles, etc.
- Raster graphics consists of pixels
- The VdW working group has published a list of questions which can support the user in the decision which format to use for which digital object
Existing archival systems[edit]
Discussion of existing archival systems
- Kopal (kooperativer Aufbau eines Langzeitarchivs digitaler Informationen)
- One softwaresystem DIAS (Digital Information Archiving System) developed at IBM and hosted at the GWDG
- One hardwaresystem located at the GWDG
- Individual modulated software: koLibRI (kopal Library for Retrival and Ingest, software package for the use of DIAS) developed at the DNB and the SUB
- Prototype of the Bundesarchiv
- Portico
- commercial
- permanent archive for reviewed scientific journals
- Lockss
- open source software
- cooperate archival system based on replications for all digital objects
Web archiving[edit]
- Concepts
- Example: the web archive of the Deutscher Bundestag
Preservation planing[edit]
Preservation planing as one main functionality of the OAIS Model
- DELOS: Testbed for the evaluation of preservation planing strategies
- PLANETS: Preservation planing environment incl. PLATO (PLANTES preservation Planning Tool)
Summary[edit]
Digital longterm preservation is a process, which can not be solved by an institute alone, because the development and implementation of strategies is very complex and costly. Therefore, a cooperation between the different organizations is highly desirable.
