This paper discusses the need for the preservation of audiovisual content in the OSGeo communities beyond the established software repositories. Audiovisual content related to OSGeo projects such as training videos can be preserved by multimedia archiving and retrieval services which are currently developed by the library community. This is demonstrated by the reference case of a newly discovered version of the GRASS GIS 1987 promotional video which is being included into the AV-portal of the German National Library of Science and Technology (TIB). Access to the video will be provided upon the release of the web-based portal, allowing for extended search capabilities based on enhanced metadata derived by automated video analysis. This is a reference case for future preservation activities regarding semanticenhanced Web2.0 content from OSGeo projects

This paper gives a work in progress report on the application of the TIB|AV Portal for audiovisual OSGeo content. The portal is a web-based platform for audiovisual media combining state-of-the art multimedia analysis with semantic based analysis, and retrieval. It meets the requirements by special libraries for reliable long term preservation, scientific citation via persistent identifiers, and applies metadata enhancement to enable innovative services for search and retrieval.
