Die Website des DOI-Desks der ETH Zürich ist neben Deutsch und Englisch nun auch auf Französisch und Italienisch zugänglich. Der DOI-Desk ermöglicht die Registrierung von DOI-Namen in der Schweiz. Dies erfolgt in Zusammenarbeit mit DataCite und der International DOI Foundation.

Der DOI-Desk der ETH Zürich ist eine Dienstleistung der ETH-Bibliothek, mit technischer Unterstützung durch die Informatikdienste der ETH Zürich (ID).

Dieses Angebot wurde im Rahmen des Innovations- und Kooperationsprojektes "E Elektronische Bibliothek Schweiz" aufgebaut. Es wird vom ETH-Rat gefördert.

DFG-Projekt: LuKII (LOCKSS-und-KOPAL-Infrastruktur-und-Interoperabilität)

10.12.2009 | Published in Internationale Entwicklungen

Scholarly information today is mainly born digital and is increasingly made available through digital means. This makes effective long term digital preservation urgent for researchers in every field. Scholars know this is important, but generally assume that others, especially libraries, will address the problem. No simple solution exists. Multiple backups are a help, but do not address problems of integrity or authenticity or usability and older backups on tape are particularly vulnerable to physical or magnetic decay.

Serious research on this topic has gone on for a decade with valuable tools such as LOCKSS and KOPAL as a result, but far more research remains to do. The problem of long term digital archiving is not solved, but becomes more solvable as the research moves forward. This project sets up a network infrastructure that takes an active step toward preserving bitstream integrity while ensuring readability, and then tests the product with materials from German institutional repositories.

Specifically this project proposes interoperability between the open-source elements of two existing archiving systems (LOCKSS and KOPAL) in order to combine cost-effective bitstream preservation with an established tool for usability maintenance and format migration.

Based on these goals the chief elements of this project are:

  1. to establish a cost-effective LOCKSS network in Germany including infrastructure to provide ongoing technical support and management for LOCKSS and its variants (e.g. CLOCKSS);
  2. to conceptualize and implement interoperability between LOCKSS and KOPAL in order to combine cost-effective bitstream preservation with well-developed usability preservation tools;
  3. and to test the interoperability prototype by archiving data from German institutional repositories.

A report on tool provision for digital preservation is now available

03.12.2009 | Published in Internationale Entwicklungen

File formats and information technology are continually evolving. In order to preserve your digital objects, you may need to perform preservation actions. Preservation action tools are software programs that act on a digital object to ensure its continued accessibility. To select the right tool, you need to know which tools are available.

Planets has wrapped a number of preservation action tools into the Planets framework.

The project has also conducted a survey of cultural heritage institutions and created an inventory of commonly used file formats and compiled a list of preservation action tools that exist to preserve them. The analysis has made it possible to identify gaps in provision.

During the analysis, it became clearer that the search for gaps in tool provision cannot be confined to availability of tools for the most occurring file formats. There are many specialized formats that need support from specialized preservation action tools, and research on this has been done through case studies.

The results of the analysis provide an important insight into the status of digital preservation and the status of digitization. More importantly, a regular analysis of the gaps in tool provision can be used to identify the need for new research and/or development of new tools. If a gap analysis shows that no tool for a specific preservation action exists, there is a gap in tool provision and a new tool should be developed.
