OVERVIEW
Certain elements are commonly used in media-related metadata definitions. This section defines these common elements in the form of the "md" namespace.
Full documentation is a combination of the written document and the XML Schema itself.
CURRENT VERSION
This annual release of Common Metadata expands people and character descriptions, expands inclusive language to people’s titles/honorifics, and provides the means to capture trivia and other interesting facts. For technical data, Common Metadata eliminates ambiguities around timecodes, and masks.
