Abstract

The Structural Metadata of the MXF file format, which has been standardised by SMPTE, contains the technical parameters of the stored material, defines how the material is played out, and provides a plug-in mechanism for Descriptive Metadata.

At the SMPTE meetings in December 2003, the specification for the MXF Descriptive Metadata Scheme - 1 (DMS-1) has advanced to Final Committee Draft (FCD) status. This means that the specification of this Descriptive Metadata plug-in is technically stable, and that publication as final standard can be expected by the middle of 2004.

In combination with the MXF Structural Metadata, the 3 Frameworks of the DMS-1 plug-in allow to encode and to interchange Descriptive Metadata, and to express the relationship of the descriptions to particular tracks and temporal segments of the material. Each of the Frameworks addresses a particular aspect of the description, namely, production related Metadata, Metadata related to the capture and creation of the material, and Metadata which describes the contents of individual scenes of the material.

In cooperation with the German section of SMPTE, the IRT organized a 2-day workshop combining users and technical experts. The workshop took place on February 3rd - 4th 2004 at IRT in Munich.

The goals of this workshop were

  • To explain the concepts of the SMPTE Metadata dictionaries, MXF Structural Metadata and the DMS-1 plug-in
  • To investigate and to present how Metadata currently used in production, news exchange and archive applications can be encoded and exchanged using DMS-1 and MXF
  • To develop guidelines how DMS-1 can be applied to satisfy the user requirements for specific applications in production interchange, news interchange and archive.

A further objective of the workshop was to guide manufacturers with respect to the implementation of MXF and DMS-1 and to formulate requirements for SMPTE with respect to further development of MXF and DMS-1.
