RELEASE HISTORY

This page details the release history of Media Manifest.

Versioning: Number changes (e.g., 1.2) constitute schema changes. Letter changes (1.1c) are documentation-only changes.

Backwards Compatible means that elements were added, but old elements still exist. Therefore, an old XML document with the new namespace will validate. All updates are backwards compatible except 1.4 to 1.5

Version 1.13

This annual release of Media Manifest incorporates digital asset metadata improvements from Common Metadata. One major improvement is the inclusion of timed metadata (timed events) in Presentation to allow rich metadata extensions tied to a timeline. There were additions to support special use cases (e.g., dub cards), and other minor improvements.
