e-Content Platforms

e-Content platforms are designed for storing, sharing, and presenting digital information.  

In addition to offering a front end for users, the operation of an e-Content platform involves:


  • data processing and normalization,
  • indexing, and
  • timely content updates.


e-Content platforms can be used to host a wide range of data, from cultural archives and journal articles to bibliometric data.


FIZ Karlsruhe operates the following e-Content platforms:

Startseite DDB

The German Digital Library (DDB)

The German Digital Library (DDB) offers everyone free access to Germany’s cultural and scientific heritage, including, millions of books, materials from archives, paintings, sculptures, monuments, films, music, and other audio-materials. The DDB is a cooperative project and exists due to the commitment of cultural and scientific institutions in Germany: Museums, libraries, archives, media libraries and other research institutions digitalize their collections, provide their data to the general public and thus make information and knowledge concerning cultural heritage available.


FIZ Karlsruhe is the technical operator of the DDB and a member of its competence network. We provide an adequate, reliable operating environment hosted at our own data processing center. We normalize data and are responsible for loading processes, and further develop the portal’s software.
