Abstract: The remaining documentation of the SMPTE Metadata Registry has moved into place within SMPTE W25. Although the individual documents are complex and closely interrelated, the full suite of standards provides a comprehensive and simple encyclopedia 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 progressed 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 reconciliation of different metadata schemes (such as EBU P/Meta, MPEG-7, and TV-Anytime) within the SMPTE infrastructure. This paper briefly reviews the structure of the SMPTE registry, seen from the perspective of a user query via the web. It presents a generic system diagram to show metadata flow, which is illustrated with an example of multiple stages of the production workflow. Finally, 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.
