[WEB4LIB] Metadata for digital video: soliciting input

[Avi Rappoport]

Howard Besser once did a great presentation on this, and he's an 
expert on exactly these topics.  I don't remember the details because 
it's not my topic, but I highly recommend checking his publications 
and pages at <http://www.gseis.ucla.edu/~howard/>
