Controlled vocabularies are appropriate for collection-alignment of video-content by providing fine-grained collections of terms. In fact, there already exist classifications and thesauri dedicated for indexing audiovisual material, but they are hardly available in interoperable formats (as e.g. RDF/SKOS), are hidden in private or public media archives or ain't use german language. Though, there is an increasing demand for audiovisual related vocabularies. We have encouraged major film archives in Germany, as e.g., German National Archive (BA), National Broadcasting Archive (DRA)
and German Broadcasting Compound to make their controlled vocabularies available for public use, but encountered a bottleneck in human- and technical resources. Therefore we plan to provide a skosification and hosting service for small and mid-sized archives. This contributions to the scientific- and film-industry community, was motivated by:
* Reuse of controlled vocabulary on films and film related material for indexing, facetted browsing, and retrieval issues.
* Interlinking and alignment of heterogeneous collections on the content-layer by using thesauri and classifications with semantic web technology such as RDF, SKOS and LOD.
* Promotion of open standards for knowledge exchange and adding value for small and middle-size archives by providing a conversion and hosting service. We plan to support the public funded media archives with manpower to make their vocabularies available in SKOS-format.
