The DFG-Viewer is a web service which presents digitized works stored in distributed repositories under a common, but simple user interface.

Status and Impact[edit]

According to the ZVDD presentation on the 97. Deutsche Bibliothekstag by Sebastian Meyer in June 2008, the DFG viewer may become the primary presentation tool for projects funded by DFG: "[...] wird die Deutsche Forschungsgemeinschaft einem Entwurf ihrer ab Oktober gültigen Praxisregeln zufolge künftige Digitalisierungsprojekte verpflichten, den DFG-Viewer als „primäres Anzeigeinstrument“ zu verwenden".

Further information is available in the article Einheitlicher Webauftritt für DFG-geförderte Digitalisierungsvorhaben by Sebastian Meyer.

Requirements of DFG Viewer[edit]

To use the DFG Viewer for the display of digitalized work, three components have to be accessible through a simple web access:

  1. The metadata of the digitalized work has to be available in the METS/MODS format
  2. The width of the digitalized work has to be between 1000 and 1500 pixel
  3. One file (108 pixel wide and 50 pixel high) with the name and the logo of the project (or institute) has to be provided

METS Profile[edit]

The DFG viewer website provides a set of documentations for the DFG METS Profile:

METS Mapping[edit]

Structural Data[edit]

The DFG Viewer provides a standardized list of structural elements which can be used for identification of the different parts within the digitized books (e.g. chapter, cover). This list also contains a mapping to the vocabulary used by the ZVDD, which is similar to the one from the DFG Viewer, but not so detailed.
