AV-Portal Gottfried-Leibnitz-Universität Hannover, a project with Technische Informationsbibliothek Hannover (TIB).

SEMEX - Semantic Media Explorer is a demonstrator that combines the latest media analysis processes to provides optimal access to video content.

MEDIAGLOBE - the digital archive is part of the THESEUS research program initiated by the German Federal Ministry of Economy and Technology (BMWi). MEDIAGLOBE deals with digitization, analysis, and semantic retrieval of historical, documentary audiovisual content.

THESEUS - Use Case CONTENTUS is a project within basic technologies are being developed to access, archive and search for multi-media cultural assets and works of art.

Semantic Games WhoKnows? and RISQ! are games with a purpose that are dedicated to create and curate semantic content.
