scope:

This amendment extends text and classification descriptors for descriptive metadata for audiovisual content making use of existing datatypes and adding some elements and attributes, and adds support for quality metadata. A first extension improves internationalization for text-based metadata by identifying the script(s) used and enables carrying encoded strings represented in multiple character sets in the same XML document. A second improvement extends classification metadata in order to: (a) improve interoperability with existing metadata formats used in professional media production, (b) increase cardinality of some elements and (c) add attributes and a version element. Finally a third extension improves the tools for describing profiles for quality control of audiovisual media, as well as the results of quality analysis on wrapper, bitstream and baseband level.
