The Deutsche
Digitale Bibliothek

Culture and knowledge online.


The German Digital Library’s aim is to make cultural and scientific heritage available to everyone.

Everyone has free access to Germany’s cultural and scientific heritage via the internet, i.e., to millions of books, archival records, paintings, sculptures, musical works and other audio documents, films and sheet music. As the central national portal, the DDB intends to interlink the digital entries from all German cultural and scientific institutions in the future. The DDB will ensure Germany’s connectivity and competitive position in science, research and education, but will also make its unique cultural heritage and knowledge conveniently accessible to all – via one central access point. By providing access to all necessary information from any PC with an internet connection, centralised access will fundamentally improve research, education and business opportunities, regardless of time and place.

As a companion of digitalisation, we create tailored solutions for every environment.

Product Details

The German Digital Library’s main challenge was to aggregate and prepare data from a multitude of data providers and to make the data available in a uniform and consistent way in the DDB portal and any other applications used by creatives. To this end, a data hub was set up which enables metadata harmonisation and data mapping to an overarching graph-based data model.

Content is made available centrally via a cross-media search engine with semantic features. For high-performance management and processing of data volumes, the DDB relies on data storage in a NoSQL database (Cassandra) and uses Spark for core processes such as loading, transforming and analysing data.
