- Abstract
- Sponsored by the German Ministry of Education and Research with funding of 800.000 EURO, the German Network of Expertise in long-term storage of digital resources (nestor) began in June 2003 as a cooperative effort of 6 partners representing different players within the field of long-term preservation. The partners include: * The German National Library (Die Deutsche Bibliothek) as the lead institution for the project * The State and University Library of Lower Saxony Göttingen (Staats- und Universitätsbibliothek Göttingen) * The Computer and Media Service and the University Library of Humboldt-University Berlin (Humboldt-Universität zu Berlin) * The Bavarian State Library in Munich (Bayerische Staatsbibliothek) * The Institute for Museum Information in Berlin (Institut für Museumskunde) * General Directorate of the Bavarian State Archives (GDAB) 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. 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 Project, 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, where, amongst other topics, a future call for action for long-term preservation was defined, described and explained against the background of practical experience.

- Abstract
- Companies, governmental agencies and scientists produce a large amount of quantitative (research) data, consisting of measurements ranging from e.g. the surface temperatures of an ocean to the viscosity of a sample of mayonnaise. Such measurements are stored in tables in e.g. spreadsheet files and research reports. To integrate and reuse such data, it is necessary to have a semantic description of the data. However, the notation used is often ambiguous, making automatic interpretation and conversion to RDF or other suitable format diffiult. For example, the table header cell "f(Hz)" refers to frequency measured in Hertz, but the symbol "f" can also refer to the unit farad or the quantities force or luminous flux. Current annotation tools for this task either work on less ambiguous data or perform a more limited task. We introduce new disambiguation strategies based on an ontology, which allows to improve performance on "sloppy" datasets not yet targeted by existing systems.

- Abstract
- The author holds a chair in Humanities Computer Science at the University of Cologne. For a number of years, he has been responsible for digitization projects, either as project director or as the person responsible for the technology being employed on the projects. The "Duderstadt project" (http://www.archive.geschichte.mpg.de/duderstadt/dud-e.htm) is one such project. It is one of the early large-scale manuscript servers, finished at the end of 1998, with approximately 80,000 high resolution documents representing the holdings of a city archive before the year 1600. The digital library of the Max-Planck-Institut für Europäische Rechtsgeschichte in Frankfurt (http://www.mpier.uni-frankfurt.de/dlib) is another project on which the author has worked, with currently approximately 900,000 pages. The author is currently project director of the project "Codices Electronici Ecclesiae Colonensis" (CEEC), which has just started and will ultimately consist of approximately 130,000 very high resolution color pages representing the complete holdings of the manuscript library of a medieval cathedral. It is being designed in close cooperation with the user community of such material. The project site (http://www.ceec.uni-koeln.de), while not yet officially opened, currently holds about 5,000 pages and is growing by 100 - 150 pages per day. Parallel to the CEEC model project, a conceptual project, the "Codex Electronicus Colonensis" (CEC), is at work on the definition of an abstract model for the representation of medieval codices in digital form. The following paper has grown out of the design considerations for the mentioned CEC project. The paper reflects a growing concern of the author's that some of the recent advances in digital (research) libraries are being diluted because it is not clear whether the advances really reach the audience for whom the projects would be most useful. Many, if not most, digitization projects have aimed at existing collections as individual servers. A digital library, however, should be more than a digitized one. It should be built according to principles that are not necessarily the same as those employed for paper collections, and it should be evaluated according to different measures which are not yet totally clear. The paper takes the form of six theses on various aspects of the ongoing transition to digital libraries. These theses have been presented at a forum on the German "retrodigitization" program. The program aims at the systematic conversion of library resources into digital form, concentrates for a number of reasons on material primarily of interest to the Humanities, and is funded by the German research council. As such this program is directly aimed at improving the overall infrastructure of academic research; other users of libraries are of interest, but are not central to the program.

- Abstract
- This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.
