1. Digital Preservation as a cooperative taskSponsored by the German Ministry of Education and Research1 with funding of 800.000 EURO, the German Network of Expertise in long-term storage of digital resources (nestor)2 began in June 2003 as a cooperative effort of 6 partners representing different players within the field of long-term preservation3. The partners include:
As in other countries, long-term preservation of digital resources has become an important issue in Germany in recent years. Nevertheless, coming to agreement with institutions throughout the country to cooperate on tasks for a long-term preservation effort has taken a great deal of effort. Although there had been considerable attention paid to the preservation of physical media like CD-ROMS, technologies available for the long-term preservation of digital publications like e-books, digital dissertations, websites, etc., are still lacking. Considering the importance of the task within the federal structure of Germany, with the responsibility of each federal state for its science and culture activities, it is obvious that the approach to a successful solution of these issues in Germany must be a cooperative approach. Since 2000, there have been discussions about strategies and techniques for long-term archiving of digital information, particularly within the distributed structure of Germany's library and archival institutions (see [2] or [3]). A key part of all the previous activities was focusing on using existing standards and analyzing the context in which those standards would be applied. One such activity, the Digital Library Forum Planning Project10, was done on behalf of the German Ministry of Education and Research in 2002, where the vision of a digital library in 2010 that can meet the changing and increasing needs of users was developed and described in detail, including the infrastructure required and how the digital library would work technically, what it would contain and how it would be organized. The outcome was a strategic plan for certain selected specialist areas (see [1]), where, amongst other topics, a future call for action for long-term preservation was defined, described and explained against the background of practical experience. As follow up, in 2002 the nestor long-term archiving working group provided an initial spark towards planning and organising coordinated activities concerning the long-term preservation and long-term availability of digital documents in Germany. This resulted in a workshop11, held 29 - 30 October 2002, where major tasks were discussed. Influenced by the demands and progress of the nestor network, the participants reached agreement to start work on application-oriented projects and to address the following topics:
At the end of the workshop, participants decided to establish a permanent distributed infrastructure for long-term preservation and long-term accessibility of digital resources in Germany comparable, e.g., to the Digital Preservation Coalition in the UK13. The initial phase, nestor, is now being set up by the above-mentioned 3-year funding project. 2. Focal points regarding contentThe major aims of nestor regarding content can be summarized as follows:
The stated aim of the expert reports is to analyse in detail the requirements in Germany as to specific topics or questions and to make recommendations, if necessary. These recommendations will then be discussed with the wider public at special workshops. Following the workshops, necessary work in these areas (project applications, groups of experts, etc.) will begin. The expert reports address the following topics:
The expert reports are being coordinated by one of the project partners. In addition, every nestor partner must address five work packages within the project period. At the end of the project, work on these five will lead to concrete recommendations, guidelines and best practices for Germany. The five work packages include:
3. German Network of excellence for digital preservationThe German network of excellence represents a cooperative approach, bringing together experts, experience, partners, interested institutions, etc., with as their primary goals: development of a common homepage for the network; development of an information platform; and development of a communication platform. 1. Development of a common homepage for the networkThe development of a homepage (http://www.langseitarchivierung.de) that combines all information, offers, reports, etc., into a single access platform, is to the fore. This platform serves as a starting point for networks and working groups, and as a place where project ideas can be interchanged and all people interested in digital long-term preservation can be brought together to share challenges, experience and knowledge. 2. Development of an information platformThe information platform consists of the following modules: subject gateway, expert database, reviews, news, catalogue, newsletter, calendar.
All of the services described above are being developed in two languages (German and English) and are based on internationally accepted standards. 3. Development of a communication platformThe communication platform provides a place for a two-way exchange between the project partners and the community. The platform enables the establishment of working groups for various topics and supports them by providing an appropriate infrastructure in terms of mailing lists, a cooperative work space system, a web-based questionnaire tool, etc. The mailing list technology used is a Sympa Mailing List Server at Humboldt-University. Initial mailing lists have been set up for the purpose of:
In addition, in order to support the working groups, a TikiWiki system has been set up.
Survey questionnaires for both the work being done on the expert reports and the work of several working groups are hosted on the same server, to guarantee interoperability of data and tools. The first survey is planned for April/May 2004 within the context of the expert report "Development of a descriptive profile for a national long term preservation strategy (Preservation Policy)". The communication platform is part of the nestor network and can be reached via <http://www2.hu-berlin.de/nestor>. 4. Long-lasting organizational conceptThe goal of the nestor project is to operate nestor like the Digital Preservation Coalition in the UK is operated. Once the project ends and nestor leaves the funding cycle, it could serve as a membership model for libraries, archives, museum, and publishers. Recently, a first step was taken to ensure the organisational stability of nestor as a cooperative network into the future: An advisory board has been established with representatives from different communities, including libraries, archives, museums, publishers, the scientific community, the open access community, and research funding institutions, and from the Conference of German Federal Ministers of Culture. 5. International integration and cooperationSeveral nestor services have been planned to make it possible for nestor to cooperate with international partners. This includes offering services in two languages as well as developing with an eye to technical interoperability. In addition, a future collaboration between the nestor subject gateway and the Australian subject gateway PADI is planned. With that in mind, nestor is using metadata compatible with OAI-PMH and Z39.50. This allows for different interfaces to be implemented quite simply within both nestor and PADI services, either for metadata exchange or for enabling distributed search via a single interface. All subject relevant metadata (keywords, classification, description, review, document type) are also available in an English language version. Nestor is already collaborating with other international working groups, such as the working group PREMIS (PREservation Metadata Implementation Strategies, http://www.oclc.org/research/projects/pmwg/). The PREMIS working group intends to develop recommendations, proposals and best practices for implementing long-term preservation metadata (PREMIS). The nestor project partner SUB Göttingen is also a member of two subgroups (WG preservation metadata, WG OAIS implementation) and will bring the results of those directly to the German community. Nestor intends to engage in future cooperative relationships with national initiatives (e.g., the Digital Preservation Coalition, the Digital Curation Center) and international projects (e.g., Erpanet, DELOS). A prerequisite for these cooperative relationships is that the different nestor services have reached a stable stage of development, which is expected by April 2004. 6.
