Metadata-Driven Workflows with MXF: A Proposal for Tagging Languages

摘要

The industry has seweral solutions for tagging files and streams with metadata intended to signal the language of a component. This paper discusses the business requirements of language tagging and proposes a scheme that is Material exchange Format (MXF)-compliant, and extensible Markup Language (XML)-compliant that builds on the most widely implemented MXF metadata standard, DMS-1. The paper illustrates examples of use of the annotation scheme and shows how accurate metadata can lead to improved identification and retrieval of material. It also shows that selecting the correct language for playout or processing requires not just the language name, but often the region, dialect, and business rules such as presence of profanity. In addition, example files, applications, and deployment are illustrated and integration with automation and asset management via XM-based interfaces are also highlighted.
