Jon W. Dunn et al. have self-archived Audiovisual Metadata Platform (AMP) Planning Project: Progress Report and Next Steps.
Here's an excerpt:
This report documents the outcomes of a workshop funded by the Andrew W. Mellon Foundation and hosted by Indiana University as part of a planning project for design and development of an audiovisual metadata platform (AMP). The platform will perform mass description of audiovisual content utilizing automated mechanisms linked together with human labor in a recursive and reflexive workflow to generate and manage metadata at scale for libraries and archives. The partners leading this planning project were the Indiana University (IU) Libraries, University of Texas at Austin (UT) School of Information, and AVP.
