Abstract
This paper describes the requirements of a programme metadata capture system for use by broadcasters in the digital age and presents solutions for implementing some of those requirements. The requirements fall into two categories, system requirements and user requirements. System requirements include expandability, data flexibility, fault tolerance, scalability and upgradeability. User requirements include access control, simultaneous visibility of data changes (referred to as active refresh), and distributed working. The proposed solutions include use of a component standard such as CORBA, with asynchronous communications and loose coupling of components; data self-description in terms of semantic types, format types and structure; and a novel hierarchical schedule representation based on schedule instructions.
