The large amount of information in audiovisual archives makes it quite difficult to efficiently locate a resource for re-use or re-purposing. In response to the needs of industries and users to solve this problem, different organisations have recently initiated active work in the definition of interoperable frameworks and representation for metadata. This paper presents recommendations given by user and standardisation organisations and addresses some of the main metadata initiatives that are relevant to broadcasting. It also presents some proposals to enable the interoperability between the different solutions.
