The third edition of the OFF standard consolidates all previously issued corrigendum and amendments and extends the existing technology providing support for a larger set of world's languages, adding new text layout features and introducing support for colour fonts and MATH expression layout
This amendment extends text and classification descriptors for descriptive metadata for audiovisual content. These extensions address existing data types and add some elements and attributes. The first one improve internationalisation for text-based metadata by identifying the script(s) used and enables carrying strings represented in multiple character sets in the same XML document, using encoding. The other 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.
