Since at least some your institutions work with sound materials I thought this might be of interest. I'm happy to answer questions about the tool should you have any. 

Apologies for cross-posting:

The Federal Agencies Digitization Guidelines Initiative Announces the Release of BWF MetaEdit
BWF MetaEdit is a free, open source tool that supports embedding, validating, and exporting of metadata in Broadcast WAVE Format (BWF) files. BWF MetaEdit is available for download at SourceForge: http://sourceforge.net/projects/bwfmetaedit/. BWF MetaEdit was developed by the Federal Agencies Digitization Guidelines Initiative to support its guideline for embedded metadata in the bext and INFO chunks (http://www.digitizationguidelines.gov/audio-visual/documents/wave_metadata.html).  The application was developed by AudioVisual Preservation Solutions (http://www.avpreserve.com/).
Users of BWF MetaEdit can: 
•	Import, edit, embed, and export specified metadata elements in WAVE audio files
•	Export technical metadata from Format Chunks and minimal metadata from bext and INFO chunks as comma-separated values and/or XML, across a set of files or from individual files
•	Evaluate, verify and embed MD5 checksums, as applied to the WAVE file's data chunk (audio bitstream only)
•	Enforce the guideline (above) developed by the Federal Agencies Audio-Visual Working Group, as well as specifications from the European Broadcasting Union (EBU), Microsoft, and IBM
•	Generate reports that show errors in the construction of WAVE files
•	Choose from command line and GUI, for Windows/PC, Macintosh OS, Linux. See the list of options at SourceForge: http://sourceforge.net/projects/bwfmetaedit/files/
