Metadata systems architecture

Abstract
During 2002 the remaining documentation of the SMPTE Metadata Registry has been moving into place within SMPTE W25. Although the individual documents are complex and closely interrelated, the full suite of standards provides a comprehensive and simple encyclopaedia of Metadata. It has long been clear that a Metadata Registry is not an end in itself. Practical applications of the Registry in emerging standards such as the Material Exchange Format (MXF) have been progressing in parallel with the Registry documentation. SMPTE is now able to examine broader issues in a Metadata Systems Architecture, including: live operation of the Registry, the end to end flow of Metadata through a production system, and the reconciliation of different Metadata schemes (such as EBU P/Meta, MPEG-7 and TV-Anytime) with the SMPTE infrastructure. This paper begins with a brief review of the structure of the SMPTE Registry, seen from the perspective of a user query of the Registry via the web. The paper then presents a generic system diagram to show metadata flow, which is illustrated with a worked example of multiple stages of the production workflow. In conclusion, the paper describes the ongoing study of mixing SMPTE and non-SMPTE metadata and a potential reconciliation of the corresponding schemas, and presents some preliminary results.
