VRT has a large audiovisual archive that is used daily. However, the contents of videos cannot be automatically interpreted by machines. Textual metadata is needed to help systems find the correct videos. By linking metadata tags to external open data sources like DBpedia, GeoNames, and MusicBrainz using semantic triples, a network of linked knowledge can be created. This allows machines to deduce extra information and provides context about resources mentioned in the metadata. Enhancing metadata with Linked Open Data technology renders the media collection more transparent by enabling innovative exploration features.
