OVERVIEW

This page details the release history of Media Entertainment Core (MEC).

Versioning: Number changes (e.g., 1.2 and 2.4) constitute schema changes. Letter changes (2.3c) 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.


Current Release

MEC has been extended to support signing metadata objects allowing the authentication of metadata provenance.
