Media asset management is the process of managing the inputs and outputs of content production and delivery which impact on process efficiency and on the effective creation of multi-purpose and re-usable media assets. Support for -metadata- - structure information about -stuff- - is recognised increasingly as critical in media systems design to support lifecycle asset management. Up to now the information has existed separately as data in business systems. From now on we expect to use electronic metadata, embedded in the media, to associate that media with its related information - thus enabling dynamic connection across infrastructure from media devices to data stored in databases. Media will be experience with its metadata - by professional and consumer alike. This paper defines -media asset management- and explores the enabling technologies required to support it, particularly process and data modelling, and the linking of metadata in media and data systems. It then takes a worked example, the lifecycle of metadata in an audio processing workflow, and concludes with a selective review of standards making.
