The AS-07 Application Specification specifies a vendor-neutral subset of the MXF file format for the long-term archiving and preservation of moving image and other audiovisual content, including all forms of Ancillary Data and other relevant materials. AS-07 defines a means for the carriage and labeling of multiple timecodes; the handling of captions, subtitles, and Timed Text; a minimal core metadata set; program segmentation metadata; and embedded content integrity data.

The AS-07 project is led by the Library of Congress and other members of the Federal Agencies Digitization Guidelines Initiative (FADGI). The main users for AS-07 are archives that maintain audiovisual content for the long term.

The specification includes a secondary version (referred to by the former AMWA term shim), intended to serve the most critical current needs of many archives: the reformatting of older analog and digital videotapes and, for some organizations, the encoding and packaging of "live" video streams sent to an archive via a serial interface.
