This paper describes an application which enables the computerassisted generation of Dublin Core-based metadata descriptions and online digital visual summaries for videos. It is a Java application which integrates a video replay window with vcr-type controls and metadata input forms generated from an hierarchical RDF schema. The schema definition is also used to validate the descriptions input by the user and control the format of the output. The generated metadata descriptions can be saved as RDF, HTML or to a database. They can be used to enable metadata interchange, searching across the Internet or dynamic generation of detailed visual summaries for video browsing. This prototype system has been developed for the State Library of Queensland’s (SLQ) Audiovisual unit to enable quick, easy, cost-effective generation of standardized metadata which can be used to create online detailed visual summaries of the latest video acquisitions.
