Guidelines: MXF Application Specification
Audio-Visual Working Group
Draft under development.
The Working Group is drafting an MXF Application Specification for Archiving and Preservation (AS-AP), a detailed specification for a file "wrapper," one key part of a digital file format for audio-visual preservation. The specification includes a list of permitted encoded essences (the underlying content bitstreams) and outlines aspects of the metadata to be embedded to support long term content management. More information is provided in the background document.
AS-AP is intended to serve reformatting programs that produce digital-file copies of videotapes, motion picture films, or other audio-visual items for long-term management. The specification is also intended to define a container for born-digital content when the native encoded essence (the underlying bitstream, as acquired by an archive) is judged to be suitable for retention for at least the medium term.
During 2010 and 2011, the Working Group has been working informally with the Advanced Media Workflow Associationexternal link (AMWA), an organization dedicated to the incubation of MXF Application Specifications and related guidelines. We anticipate that AMWA will guide the drafting process in a more formal way during 2012.
We encourage participation by other interested audio-visual archives. Please send us your comments.
